We're proud to announce that our 2019 Community Survey results are now available! We conducted a survey between September and November 2019 to determine how organizations are using the Payara Platform and what ecosystem components are most commonly used with the platform. Thank you for contributing and helping us gain insight into which features and enhancements the community would most like to see in future releases of the Payara Platform.

Payara Micro instances can join a cluster automatically. They could also join the Domain Data Grid as well as standalone Payara Server instances. In this blog, I explain how to join Payara Micro instances to the Data Grid in the Admin Console.

Payara Microインスタンスは自動的にクラスタを構成することができます。また、Payara Serverのスタンドアロン・インスタンスと同様にドメイン・データ・グリッドに参加させることもできます。このブログでは、管理コンソールを使用してPayara Microインスタンスをデータ・グリッドへ参加させる方法についてご説明します。

Integration testing is perceived as difficult, time-consuming and requiring complex setup of 3rd party systems. There are different types of integration testing, such as system, acceptance and release testing, but all types of testing share the need to integrate several units of your application or other systems in your test.

For the festive season we decided to change it up abit and create a mega bumper edition of the month catch by combining November and December and serve it to you before many head off for their Christmas holidays. 

Below you will find a curated list of some of the most interesting news, articles and videos from this month. Cant wait until the end of the month? then visit our twitter page where we post all these articles as we find them! 

Amazon Corretto is a distribution of the Open Java Development Kit (OpenJDK) provided by Amazon. It's free to use, comes with long-term support, is production-ready and supported in multiple platforms, which means that it can run in the cloud, on-premise, and on your local machine. With Corretto, you can run Payara on popular operating systems, including Linux, Windows and macOS. It is certified using Java Technical Compatibility Kit (TCK) to meet Java SE standard and can be used as a drop-in replacement for most JDK distributions. 

Payara Platform 5.194 was released recently, and just like the previous release, it is a certified Jakarta EE implementation. The request for certification can be seen on Jakarta EE platform project issue tracker.

As you may have heard, Payara Platform 5.194 is now released! And with a boatload of new features, improvements and bug fixes, it also marks JDK 11 support coming out of tech preview! With much excitement from users, JDK 11 support has been in technical preview since 5.192.

皆様に大きなお知らせです。Payara Serverの新しいバージョンが、多数のバグ修正と安定した新機能とともにリリースされました。それらについて以下をご覧ください。

Great news for everyone! Today we released a new version of the Payara Platform (5.194) with many exciting new features including production-ready JDK 11 support, Monitoring Console and MicroProfile 3.2 support. This release introduces 50 bug fixes, 13 new features, 20 improvements and 4 component upgrades.

The Java Virtual Machine comes in different flavors. On one hand, you have the OpenJDK based JVMs. Many vendors, including Oracle, RedHat, Amazon, and Azul to name just a few, create builds from the OpenJDK source to bring the JVM to your development machine or server.

Payara Platform has implemented MicroProfile OpenTracing with its own tracer that can be sent to other sources via the notification service. But maybe you don't want to use Payara's Tracer, and instead want to use a different one - now you can, starting from Payara Platform 5.194 onwards.

We are happy to announce that from the Payara Platform 5.194 release onwards Payara Server ships with a built-in monitoring console that allows a visual peek under the hood of the server.

With the release of Payara Platform 5.194 (coming in December), Payara will officially be MicroProfile (MP) 3.2 compatible. But what's the big deal about this? In this blog, we'll be taking a look at the benefits and features of the upgrade and why you'll want to make use of it.

At Payara Services, we have long been advocates of the benefits of using DevOps practices not only in the development of our products (like Payara Server & Payara Micro), but also in the core of our expert advice to our user base with our blog containing arguments for using DevOps practices, details of DevOps tools and new developments that benefit it.

Apologies for the late edition this month! Your humble author has been on the road with recent conferences in Europe. But I hope I can make it up to you!

In a recent article we showed you how to configure pools and resources in Payara Server. One question from the comments on that blog was:

Payara Platform 5.193 includes full support for MicroProfile Metrics 2.0. While MP Metrics has been covered in previous blogs, some important changes have been introduced that we will cover here.

Each year, there's one special Java conference for me. It's GeeCon in Prague because Prague is my home city where I work and live and where I know so many great people in the Java community. This year, I had the opportunity to be a part of GeeCon again as a speaker. As is true every year, GeeCon was well organized, with a lot of interesting international and local speakers and a huge crowd of passionate attendees. All of this made the conference exceptional and worth attending.

このたび、Jakarta EE 8 TCKの約50,000のテストにすべて合格し、Payara Server 5.191.1がJakarta EE 8 Full Profile互換であるとご報告できることを、私たちはとても嬉しく思います。

This is an updated blog of the original which was published in May 2016

Payara Server provides the Health Check Service for automatic self-monitoring in order to detect future problems as soon as possible. When enabled, the Health Check Service periodically checks some low level metrics. Whenever it detects that a threshold is not met, it triggers alert notifications that allow to detect undesired behavior and predict possible failures. All of these automatic checks are very lightweight and run with a negligible impact on performance.

Maybe you've already heard about Eclipse MicroProfile, or maybe you don't know what benefits it offers you in your current project. Perhaps you don't see the relationship with Java EE/Jakarta EE - or how you can use it with Payara Server or Payara Micro.

In this blog, I'll give you a short overview of all of the above questions so that you can start using MicroProfile in your next project on the Payara Platform.

Arshal Ameen, the application architect atRakuten Card - the number one credit card issuer in Japan- recently spoke at the 2019 Kafka Summit. His talk focused on how Rakuten Card is driving innovation in a traditionally conservative Japanese tech culture and how Payara Enterprise Support is helping out on this journey. He also shares further information about the company’s future plans for its Payara environment.

We are very happy to report that we've successfully passed all of nearly 50,000 test suites of Jakarta EE 8 TCK, and Payara Server 5.193.1 is Jakarta EE 8 Full Profile compatible!

Payara Server 5.193.1 is Fully Certified as an Open Source Jakarta EE 8 Compatible Implementation

This month we had Oracle Code One dominate the lions share of everyone's attention with talks and announcements. So you will notice I have included more than my usual amount of videos, that feature some of the talks and panels from the event. Shortly afterwards was the first Jakarta One Virtual conference that finally announced Jakarta EE 8! Which explains the a large rise in Jakarta EE and MicroProfile content. 

Below you will find a curated list of some of the most interesting news, articles and videos from this month. Cant wait until the end of the month? then visit our twitter page where we post all these articles as we find them! 

This was my first time attending Oracle Code One, and by extension traveling to San Francisco.

This year marked the second edition of the Oracle Code One conference, which was formerly known as Java One. The conference is one of the most important Java conferences in the world and rightly so for many reasons! Which means that we at Payara couldn't miss being there. We were extraordinary busy at the conference, so we want to share with you a short summary of what happened, what it meant for Payara and for the whole Java community in general.

Introduction

With Container orchestration tools like Kubernetes and Docker Swarm, you can add instances quite easily. Depending on the type of clustering you need or use for your application, some scenarios are easier to implement than others.

On September 16, 2019, the Eclipse Foundation received the 2019 Duke's Choice Award for Jakarta EE in recognition for open source contributions to the Java ecosystem and the community-driven achievement of moving Java EE from Oracle to Jakarta EE.

When creating instances, it can sometimes be a chore remembering what names are already in use or even coming up with a name to use in the first place!  The Dynamic Instance Naming feature, sometimes called auto-naming, introduces a new option to the create-instance & create-local-instance commands that, when enabled, will resolve any name conflicts or generate a name for you.

If you want to run and debug your application from within an IDE using Payara Micro, you need to take different steps and use a different configuration then when you run the application with Payara Server. With Payara Micro, you can start the runtime from a jar file with no previous installation step. In this blog, I'll show you the steps to use IntelliJ IDEA with Payara Micro and how you can perform a hot reload of the application.

モニタリングとは？ロギングとの違いは？

モニタリングとは、サーバーのコンポーネントやサービスの実行時の状態をチェックすることをいいます。

サーバーの状態をチェックする方法としては他にロギングも存在しますが、ロギングはサーバーが自身の状態を記録し外部へ伝えるのに対して、モニタリングは外部からサーバー内部の状態を計測する点が異なります。

As part of the Payara Enterprise Support services that we deliver to customers on a daily basis, giving expert advice and clarifying how the internals of the products of the Payara Platform work is one of the most common scenarios we encounter. Here's' a story about the advice we gave to one of our customers regarding the behavior of JDBC Connection Pools in Payara Server.

The Jakarta EE 8 Full Platform, Web Profile specifications and related TCKs have been officially released today (September 10th, 2019). This release completes the transition of Java EE to an open and vendor-neutral process and provides a foundation for migrating mission-critical Java EE applications to a standard enterprise Java stack for a cloud native world. 

If your business processes branded credit card data (such as Visa, MasterCard, American Express, and Discover), you must comply with the Payment Card Industry Data Security Standard (PCI DSS). The requirements were developed and are maintained by the Payment Card Industry Security Standards to reduce credit card fraud and implement increased controls around cardholder information. For companies using the Payara Platform, having a Payara Enterprise support subscription helps you maintain compliance.

August felt a little bit quieter than previous months, with many people gearing up for the busy conference season. However there were still plenty of juicy pieces of content to be found.

With the summer season coming to a close, the time has come for a new release of the Payara Platform! Here's a quick list of the new features you'll have to look forward to with the Payara Platform 5.193 release:

Introduction

Application updates are required as part of the normal maintenance process of your application lifecycle management. These updates should be as smooth as possible, and especially for a micro-services environment, performed with zero-downtime of your Payara Micro application. The Kubernetes Rolling Upgrades feature can help you with this.

In this blog, I'll discuss the basics around Kubernetes ConfigMaps and Secrets and give two examples of how you can use them in combination with Payara Micro.

Request tracing has been a feature in Payara Platform for a number of years now, and over time it has evolved and changed in a number of ways. The crux of what the feature is remains the same, however: tracing requests through various parts of your applications and the Payara Platform to provide details about their travels.

This blog aims to give you a short overview of Hybrid Cloud, its benefits and limitations, how to tackle these limitations and finally - why the Payara Platform is the right choice if you are thinking about migrating your business to Hybrid Cloud.

What is a Security Realm?

A security realm in Payara Server is a component used to authenticate users. Despite all the complicated terminology used in Java EE security, which is not helped by different application servers having their own terminology to describe the same thing, that's fundamentally all it is. The 'certificate' realm is a Payara Platform-specific component used to authenticate users using a certificate store. This will be used, for example, in client certificate authentication.

It's 6 months since I posted our last roadmap update and the team have been working hard to deliver what we promised at the beginning of the year and have released both our 191 and 192 releases since then. I therefore thought it was a good time to reflect on what we've delivered so far and what we've still got to do.

Another great month in the bag. There were awards, conferences, out of incubation releases, competitions, surveys and lots more going on.  Below you will find a curated list of some of the most interesting news, articles and videos from this month. Cant wait until the end of the month? then visit our twitter page where we post all these articles as we find them! 

In this blog, I will explain how to deploy applications using the Payara Server Admin Console. You can also watch this super short video (under 2 minutes) to see how to deploy applications using NetBeans, the Payara Server Admin Console, or using admin commands.

Since Payara Server 5.191, the Admin Console has embedded online help. It was imported from Eclipse GlassFish and offers assistance for you when using the Admin Console.

Last week, the Colombian chapter of the Latin American JConf Conferences was held in the beautiful city of Medellin, Antioquia. There were multiple Java related talks across the 5th and 6th of July in two tracks:

Java EE Security API is one of the new APIs in Java EE 8. With Java EE currently being transferred and rebranded to Jakarta EE, this API will soon be rebranded to Jakarta Security, which is the term we'll use in this article. Jakarta Security is part of the Jakarta APIs, included and active in the Payara Platform by default with no configuration required in order to use it. With some effort, Jakarta Security can be used with Tomcat, as well.  

Payara Tools 1.0 Eclipse Plugin just got a small, but important update for JDK 11 users.

ロギングはアプリケーションを上手く動作させる鍵となるコンセプトのひとつです。ログはアプリケーションとサーバーが何をしているのかを示してくれます。そして当然のことながら、ログは何かおかしなことが起こったとき、最初に見るべきところとなります。

このブログでは、管理コンソールからアプリケーションをデプロイする方法についてご説明します。

管理コンソールからJDBC接続プールを作成する手順について説明します。この例では、H2インメモリ・データベースを使用して “test” という名前の接続プールを作成します。

The term “Kubernetes” comes from the Greek “kubernan,” which means to steer or guide. You can think of Kubernetes like a pilot for apps that are stored and run together in containers and other forms of workload distribution software. The Greek “kubernan” was transformed over the years to relate to the term “Govern”, which is another helpful comparison when trying to understand the full capacity of Kubernetes.

Another very busy month for the Payara team! We had our annual "Payara Week" where we fly everyone in the company to our UK HQ for a week of close collaboration, celebration, review and fun! We also announced our new partner program "Payara Radiate".

This week we were happy to host  William and Imogen who joined us in the Malvern Office for a work experience placement. As an organisation we have been dedicated to involving ourselves and providing educational opportunities for young students. Including our apprenticeship program, work experience placements, speaking at schools and events. Below is a summary from William and Imogen on how they felt about the experience.

Payara Server 5.191 から、管理コンソールに埋め込みのオンライン・ヘルプが備わっています。これは Eclipse GlassFish から移植されたもので、管理コンソールを操作する上で役に立つものです。

Voxxed Days Luxembourg were organized for the fourth time in the south of the country in the village Mondorf-les-Bains, near the borders of France and Germany. If you want to visit the region, you can enjoy the nice views and vineyards. The Moselle wine is produced here.

On the surface, the changes between Fault Tolerance 1.1 and 2.0 are straightforward. The main new feature is allowing use of the @Asynchronous annotation on methods returning CompletionStage which allows for more elegant composition of asynchronous computation.

An increasing number of organisations have moved, or are planning to move, to cloud-based hosting and are developing their applications to run in the cloud. However, once it's decided that your next application is going to run in the cloud, there are still a lot of architectural choices ahead of you. Besides obvious benefits like cost reduction, scalability and easier administration, cloud environments bring their own disadvantages and potential risks. In this blog, I'll share with you some tips on how to take care of the most important disadvantages and risks when you decide to build your applications for the cloud.

We will look at the various options for running your application:

Whilst cost is an important consideration when choosing a cloud provider, there are other things that you need to take into consideration before making your decision. To help, here are the top 5 tips for choosing the right cloud provider for projects based on Payara Server or Payara Micro and your business needs.

Several Cloud Providers have the possibility to run your Payara Platform Docker Images on their infrastructure. In this blog, I will describe to you how you can run your application on Microsoft Azure using a Docker Container. All the steps required to perform this are described using the Azure Portal (web-based application) and the Azure Command line.

Kubernetes is most commonly used with Docker managed containers, although it doesn't strictly depend on it. Kubernetes defines a Container Runtime Interface (CRI) that container platforms must implement in order to be compatible. These implementations are colloquially known as "shims". This makes Kubernetes platform agnostic so that instead of Docker you're free to use other platforms with corresponding shims, such as CRI-O or KataContainers.

Eclipse MicroProfile has just announced the release of MicroProfile 3.0. This version builds on MicroProfile 2.2, including major updates to the Rest Client, and introducing breaking API changes to Metrics and Health Check APIs.

HK2 is a rather old dependency injection (DI) framework and is used as the core of Payara Server. Created in 2007 by Kohsuke Kawaguchi (who is also the creator of the Hudson project, now Jenkins) at Sun Microsystems, it followed JSR 330 closely, which was the JSR that introduced the @Inject, @Named and @Qualifier annotations, the very annotations which are also heavily used in CDI.

The concept of a Docker node and instance are introduced in Payara Server 5.192 as a tech preview. The aim of these is to provide better native integration of Payara Server with Docker.

2019年5月、Payara Teamは初めてとなる日本全国ツアーを行いました。過去、東京と大阪ではJUGと共催でイベントを行ったことはあるのですが、今回は2週間で日本全国5都市をまわるという大きなものでした。

This was a big month for the Payara Team. We just released Payara Platform 5.192, we toured all across Japan and there has been plenty going on in the Java world with the announcement by the Eclipse Foundation regarding the continued use of the javax namespace. 

The Payara Platform 5.192 release comes with an update to MicroProfile. Compared to  MicroProfile 2.1, four components were updated in MicroProfile 2.2:

When a leading telecoms company in Switzerland, Swisscom, transitioned to Payara Server from GlassFish for their mission critical applications, they found the migration easy and without problems. In fact, having Payara Enterprise Support meant Swisscom had access to a customer-only build which shortened the time to getting a fix to test by two months and 24x7 access to Payara engineers.

One of the biggest challenges when developing applications for the web is to understand how they need to be fine-tuned when releasing them into a production environment. This is no exception for Java Enterprise applications deployed on a Payara Server installation. 

Running a Payara Server setup is simple: download the current distribution suited for your needs (full, web); head to the /bin folder and start the default domain (domain1)! However, keep in mind that this default domain is tailored for development purposes (a trait inherited from GlassFish Server Open Source). When developing a web application, it’s better to quickly code features, deploy them quickly, test it, un-deploy (or redeploy) it and continue with the next set of features until a stable state is reached. 

When using Docker images as the way to deploy your application, many organizations use Kubernetes to manage the containerized version of their application. This blog gives you a short overview of Kubernetes and how to run your Payara Micro application in a scaled fashion by either defining the scaling manually, or automatically by the Horizontal Pod scaler.

The 2019 Jakarta EE developer survey results are in - and they show cloud deployments have increased since last year with 62% of Java developers currently building or planning cloud native architectures within the year.

Today the Eclipse Foundation have announced an Update on Jakarta EE Rights to Java Trademarks which has dramatic implications for the future of Java EE and Jakarta EE. The Payara team have only recently learned about this - so we thought we would blog about how we feel this impacts customers and users of the Payara Platform. We'll also give our thoughts on how Jakarta EE should evolve given the constraints outlined in Mike Milinkovich's blog from the Eclipse Foundation.

This is the first article of “Basics of Payara Server Admin Console” blog series. I’ll explain how to use Admin Console of Payara Server in this blog series. In this article, I’ll explain the concept of Admin Console and its role in Payara Server, which is important before you start using the Admin Console.

We are thrilled to be again sponsoring the JConf Colombia conference this year.

Hello and welcome to the second issue of our monthly round up where we feature a curated list of interesting articles and videos created by the community that we have enjoyed and found interesting.

Nowadays, the concept of microservices is more than a simple novelty. With the advent of DevOps and the boom of container technologies and deployment automation tools, microservices are changing the way developers structure their applications. With this article, our intention is to illustrate that microservices are a valid option for Java/Jakarta EE developers and how Payara Micro is a robust platform to reach that goal. 

Java EE 8 introduced a new API called the Java EE Security API (see JSR 375) or "EE Security" in short.

This new API, perhaps unsurprisingly given its name, deals with security in Java EE.  Security in Java EE is obviously not a new thing though, and in various ways it has been part of the platform since its inception.

So what is exactly the difference between EE Security and the existing security facilities in Java EE? In this article we'll take a look at that exact question.

We are extremely excited to announce that we will be touring Japan in just a few short weeks. We have teamed up with some of the most prominent Java User Groups in the country and will be delivering a range of talks.

これから数回にわたって、Payara Serverの管理コンソールの基本的な使い方について解説してゆきたいと思います。第1回目は、Payara Serverの管理コンソールの概要と、管理コンソールを使用する上で理解しておきたいPayara Serverのコンセプトについてご説明します。

There are many acronyms in the Java world. Here's a list of some commonly used acronyms and what they mean.

JCP - Java Community Process

The Java Community Process is simply the process by which Java EE was developed. It's an open process that anyone can apply to become a part of. To find out more about the JCP, visit their website: https://www.jcp.org

It is now common knowledge that there are considerable advantages to moving your applications to the cloud. From improving resource usage and agility to lowering operational costs, the cloud can provide your organisation with a competitive edge. 

You might already know that Payara Server originated out of a Glassfish fork. Glassfish being the reference implementation server of Java EE. Let's take a closer look at the components and modules that make up Payara Server.

Payara Platform 5 brought with it an implementation of Servlet 4.0, which itself contains support for the HTTP/2 standard. HTTP/2 support in Java has been fairly obscure for JDK 8 users, causing issues for many depending on their JDK minor version. This blog hopes to clarify the state of HTTP/2 in Payara Platform 5.

Hello and welcome to the first issue of our monthly round up where we feature a curated list of interesting articles and videos created by the community in the last month that we have enjoyed taking in.

A variety of solutions are now being delivered to our growing global customer base through the efforts of Payara’s local partners. In addition to removing any language barriers that may exist, our partners help reinforce the numerous benefits for choosing the Payara Platform.  

We are proud to announce that Rakuten Card has recently received the IT encouragement award for delivering "Highly available financial services using open source application server and global collaboration with Payara". 

Goals of the Payara Platform

Four years ago when I made the first pull request into the Payara repository the team had a number of goals in creating Payara Server. The first was to build a robust, reliable and supported open source application server that could be deployed into production environments and the second was to evolve the Payara Platform to enable Java EE developers to embrace new architectural models and new deployment infrastructure like cloud, IOT and containers. We have achieved many of these goals and driven forward others, and they are still our primary focus as we look towards Payara Platform 6.

So, I recently dove into the world of esolang and weirdlang programming languages, where the creators try to take the idea of a programming language to the limit with over the top minimalism or weirdness. Here are 6 programming languages I thought were interesting – and some of the weirdest or most obscure!

Payara and GlassFish have supported classic remote EJB since its inception. Classic remote EJB uses RMI-IIOP (Remote Method Invocation over Internet Inter-ORB Protocol ) for transport and CSIv2 (Common Secure Interoperability Protocol Version 2) for security.

The 5.191 Payara Platform release brought with it support for MicroProfile 2.1. For those who don't know, the only specification updated in this version of MicroProfile was OpenTracing, going from 1.1 to 1.2.

The world is moving in fast forward and the Java ecosystem is no exception. In 2017, the release of Java 9 disrupted the Java ecosystem with the introduction of Java modules. Soon after, the new six months Java release cycle caused another disruption, with three new Java major versions released since then. The Payara team have been working hard to keep up with this new, faster velocity. Although the latest Payara Server version 5.191 doesn’t run on Java 11 yet, we’re very close and can confidently say the next version of Payara Server will run on Java 11.

Recently two of our engineers sat down to have a chat with Adam Bien on his podcast airhacks.fm . The podcast discussion covered everything from their very first time programming to their current day issues and projects.

In many films that feature computer technology, the film makers often find it necessary to apply some artistic license to its portrayal or force the audience to suspend belief for the sake of the plot. However, sometimes they simply ask too much from an educated audience! Here is a list of some of the worst offenders!

There's a lot of noise revolving around Docker at the moment, and with the current industry focus on the cloud, there's a good reason for that.

I hope you would already know why you might want to use Payara Platform in your business, so in this blog I'm going to focus more on why you'd specifically want to use it with Docker in a "business" context. For a start, if you're unfamiliar with Docker, please refer back to our introductory blog: What is Docker and How is it Used with the Payara Platform for a primer.

Introduction

At the end of February 2019, we started with the phase-out of the Payara Platform 4. It does not mean the end of it, but a first waypoint in the lifecycle of it. You can see all phases of a Payara Platform on our Support Lifecycle page on the website (https://www.payara.fish/support/support-lifecycle/)

Did You Know?

One of our key goals for the Payara Platform is to enable developers to use the Java EE skills they have honed over many years to take advantage of new infrastructure, architectures and programming models. We fundamentally believe that a managed runtime platform combined with industry standard APIs like Java EE and in the future Jakarta EE is a perfect fit for cloud and containerized infrastructure. Java EE has always separated the development of applications from the construction and management of the infrastructure to run those applications using the concept of deployment artifacts. This has a natural fit to cloud and container platforms including in the future serverless models.

A change in the year means a change in our version number! Slightly later than our usual release month of February, we've tried to include some more changes in the release than a simple number change to make the wait worthwhile: read on to find out more!

Did You Know?

Migrating from Oracle WebLogic Server to Payara Server can be a simple and straightforward process because both servers rely on the Java EE specifications. Check out our guide for some useful advice on how to migrate!

What is Docker?

Docker is a platform which makes it easier to create, deploy and run your applications using containers. A container bundles all the software needed to run it. By packaging the required dependencies, it makes it easy to run it on any machine, regardless of small configuration differences.

MicroProfile

For those who did not come across Eclipse MicroProfile yet, let me give you a quick introduction. In 2016, a group of vendors and individuals started an initiative to optimize Enterprise Java for a microservices architecture.

I have written and talked a lot about why reactive programming matters. It’s always been a topic of personal interest for me. I’m not only an engineer but also a perfectionist and I’ve always wanted my applications to be perfect, easy-to-use and pleasant to work with. Building reactive applications is one way to achieve this perfection.

As 2019 is in full swing, let's reflect on the highlights of improvements for the Payara Platform in 2018 and review the plans for enhancements and changes coming in 2019.

Have you ever been in a situation where something not-so-good happened, and you looked back and said “man, I wish I had….” Most of us can think of a time in our lives when we had the opportunity to prevent an undesirable outcome by acting – and didn’t. For example, have you ever planned a trip and declined the purchase of travel insurance, only to find out you have to cancel the trip? You wished you had paid the extra expense to get the insurance, right? Many businesses find themselves in a similar situation when they take a reactive approach to their IT support needs, waiting until a problem presents itself before finding the resources to solve it. Unfortunately, this reactive response to support ends up costing you more in downtime, resources, efficiency and money in the long run.

This short video introduces two of our apprentices who are currently also studying for a degree in Technology.  They talk about what they are learning, the challenges they face, their future plans, what they enjoy and what they are currently working on. If you are currently considering a Degree Apprenticeship we hope this may prove helpful. 

Eclipse GlassFish 5.1 がついに正式リリースされました。

Today Eclipse GlassFish 5.1 has been released, and unlike the modest increase in version number might suggest, this truly marks a major milestone. Not just for the GlassFish project itself, but for Java EE and moving Jakarta EE forward even more.

Logging is one of the key concepts for successfully running your applications. It tells you what your application and server is doing. And of course, logging is the first place you should look when things go wrong.

In this getting started blog around logging, I will explain you the basic concepts of the Payara Server logging module. This should help you get started in the logging journey. (Click here to read the rest of our Getting Started blog posts).

As of this month, there will no longer be any public JDK 8 releases. This means that security fixes won't be publicly accessible. A Payara support contract lets you take advantage of Payara's partnership with Azul, providing you with access to Zulu Enterprise. This means that you will have access to all future JDK 8 security fixes. Below are some common questions we receive regarding Zulu Enterprise and how it works with a Payara support contract.

As presumably well known by now, Java EE is in progress of being transferred to the Eclipse Foundation. A lot of work, partially behind the scenes, has been done to make his happen. This work included discussions between vendors and other interested individuals, the vetting of the code in the Java EE repo at GitHub, actually transferring the code from the Java EE repo to the Eclipse repo, and most recently the preparation of the transferred code to be buildable on Eclipse Foundation infrastructure and changing the Maven coordinates over from javax.* to jakarta.*

The goal of MicroProfile.IO is to optimise Java EE for a micro-service architecture. It is based on some of the Java EE specifications and standardise a few technologies from the micro-services space.

Maintenance mode is the stage of the product lifecycle where we're no longer releasing new features for Payara Server 4 or Payara Micro 4, releases will only contain bug fixes.

In November, my friend Milen Dyankov started it all by inviting me to come to Warsaw to give a talk at a local developer meetup (sponsored by Liferay, Milen's employer). After attending several big conferences during the year, coming to talk at a much smaller event sounded quite relaxing! Visiting Warsaw for the first time was also tempting so I agreed to attend.

Java EE 8 fully supports asynchronous handling of REST requests and responses, on both client and server side. This is useful to optimize throughput of an application or even when adopting reactive principles. MicroProfile type-safe REST client API also supports this concept to allow you to call REST services asynchronously with a much more straightforward way with plain Java interfaces.

Payara Server provides many metrics within JMX beans. The most interesting metrics are the statistics around pools for HTTP threads and JDBC Connection pooling.

On the other hand, Payara Server also implements the MicroProfile Metrics specification. The retrieval of useful metrics from the running instance in the areas of CPU, memory, Class loading, and other MicroProfile specifications (like Fault Tolerance), are possible through the implementation of the MicroProfile Metrics in Payara Server.

In the previous blog of this series, we learned different ways to troubleshoot Java EE application. This blog will continue to focus on different ways and techniques to catch potential issues in the early stages and how to find the root cause of application performance issues.

To run your application or server over HTTPS you're going to need a certificate. Commonly referred to as an SSL or TLS certificate, this is a guide on how to register one using Let's Encrypt's Certbot and then how to configure Payara Server to use it.

As you probably already know, Oracle decided to stop providing public updates for Oracle Java Development Kit 8 (JDK 8) in January 2019. Public updates and security fixes will be provided by Oracle only for the latest version of Oracle JDK, for 6 months until the next new version. While personal users will still continue to get updates for Oracle JDK 8 until December 2020, commercial companies that plan to use it after January 2019 will either need to become Oracle customers or switch to a JDK 8 distribution supported by someone else to receive regular updates with critical and security fixes.

In a distributed micro-services architecture, it is important to have an overview of your systems in terms of CPU, memory management and other important metrics.

The Payara Support Lifecycle policy ensures longevity of your Payara Server or Payara Micro (The Payara Platform) investment. We provide 10 years of support and a well-defined lifecycle model to maintain the stability of your production environment.

Starting in February 2019, Payara Server 4 and Payara Micro 4 are moving from Full Support to the "Maintenance" stage of the lifecycle. No new features, enhancements, or APIs will be released for the Payara Platform 4 after February. What does this mean for you? Should you upgrade to Payara Platform 5?

This is an update of the article "How to Upgrade Payara Server."

Since Payara Server is on a regular and frequent release cycle, we get a lot of questions on how to upgrade to the latest version while maintaining existing domain configurations.

Hazelcast in the Payara Platform offers several ways to configure how instances cluster. One new way is by using DNS records.

Watch the recorded webinar with Senior Service Engineer, Fabio Turizo to learn more about:

I've been to Sofia, Bulgaria, a couple of times already. It all started with the Java2Days organizers inviting the Payara team to give a talk 2 years ago. But this time it was something special. The organizers joined forces with other IT conferences and prepared a special edition for its 10th anniversary in what is probably the largest building in Bulgaria - the National Palace of Culture.

Java SE comes with many security primitives upon which Java EE builds. JAAS for instance is a well known API in this context, from which Java EE uses the Principal, Subject and to some degree the LoginModule types. The Java EE security APIs JACC and JASPIC make direct use of these types.

If you don’t already have a JDK installed, you’ll need to download and install one before you can deploy Payara Server. We recommend Zulu®, an OpenJDK that is fully compliant with the Java SE standard, 100% open source, and can be downloaded and used for free. Also, should you ever purchase support for the Payara Platform, support for Zulu OpenJDK is included.

Download Zulu OpenJDK from their website: https://www.azul.com/downloads/zulu/

Wondering what the January 2019 changes to Oracle JDK mean for your business? Join Senior Payara Services Engineer, Fabio Turizo, for a short, informative webinar and get your questions answered!

You probably know that a DAS, or Domain Administration Server is an instance of Payara Server, but you probably don't know that from the console of Payara Server you can now manage an instance of Payara Micro directly from the DAS. This means from within the admin console you can send your asadmin commands directly to any Payara Micro instance within your cluster.

The JVM Conference is a smaller conference with two tracks. But smaller doesn’t mean it is not worth attending. There is a very broad variety in topics from plain Java SE, backend development, to micro-services and containers in cloud environments with sessions aimed at Java programmers, operators, QA staff and IT architects. You can get up to speed in the latest trends in many areas.

There has been a lot of noise around MicroProfile for quite a while now, and one of the specs provided by MicroProfile are Health Checks. The aim of this spec is to allow you to write a number of health checks that will run when you hit a specific endpoint, the intention being that this endpoint can be periodically poked by a container orchestrator to determine if an instance is responsive and healthy.

We recently held a webinar hosted by myself, Arjan Tijms and Ondrej Mihalyi based on exploring and demonstrating the latest features and updates in the 184 release. This included:

Starting this year, customers that come on board with our support services also have access to commercial OpenJDK support included, thanks to the partnership between Payara Services and Azul Systems' Enterprise Support! If you are interested in Payara Enterprise or our Migration & Project Support but are hesitating and have some doubts about what value this service brings to your organization and environment, this article may help dispel them and give you much needed decision-making clarity.

(This is an update of this blog written in 2016: Making Use of Payara Server's Monitoring Service)

Payara Server has for a while now included a JMX Monitoring Service which can be used to log information from MBeans to the server log. Using the JMX Monitoring Service, you can monitor information about the JVM runtime such as heap memory usage and threading, as well as more detailed information about the running Payara Server instance. The information is logged as a series of key-value pairs prefixed with the string PAYARA-MONITORING:, making it easy to filter the output using tools such as Logstash or fluentd.

For some time now there has been an undeniable growth of interest for Microservices, as somewhat evidenced by the following graph from Google Trends:

With the new release cadence of a major release of Java every 6 months, which was introduced a year ago with Java 9, a lot of uncertainty about an update strategy arose.

Having previously blogged about setting up data sources in Payara Server, we thought we should mention that you can also set up data sources in Payara Micro. In this blog, we'll take you through the process of setting up a data source using Payara Micro, including code snippets and where to find full code examples. Let's get started!

Recently we shared a blog about Ondrej's talk prepared for Code One and Devoxx conferences: Be Reactive and Micro with a MicroProfile Stack. Now, we have his video so you can watch the talk as if you were there! We also enjoyed several other MicroProfile related talks at Devoxx and wanted to share some of those as well. See below for a talk about Jakarta EE MicroProfile WebStandards by Adam Bien, a Java EE/Jakarta EE and MicroProfile discussion with Sebastian Daschner, and a talk about Securing Microservices from Emily Jiang.

JConsole is a useful tool for monitoring Java processes. You can collect data from a Java process such as: heap memory usage, thread count, CPU usage, classes loaded and MBean data. This allows you to gauge whether any Java process is using too much system resources. This guide will show you how to monitor Payara as a local process (on the same machine), or a remote process. This blog will assume that you've got a valid JDK and Payara install.

In this video demo we show you how to use the Domain Data Grid which was introduced as a new feature in Payara 5. As well as further demos using Payara Server and Payara Micro on Microsoft Azure.

Our goal within the Payara project is to facilitate innovations in Java web and enterprise applications. There are many areas to innovate but one of my favourite is better and simpler support for reactive programming. I've been exploring this area for a while. I have found some clever ways how to use standard APIs and Payara Platform to write reactive applications. This year in one of my session at Oracle Code One and Devoxx Belgium, I will focus on using MicroProfile API to write reactive microservices with simple code.

In the previous blog of this series, we learned about 5 production features of the Payara Server 5. This blog will continue to introduce 5 more production features of Payara Server 5 that you might not know about - but should.

At Java One last year, Oracle announced that they had made the monumental decision to open source Java EE and move it to the Eclipse Foundation. As Oracle Code One (the successor conference to Java One) comes around I thought it would be good to reflect on where we are and how far we still have to go.

When support for the GlassFish application server ended, Payara Server entered the market as a fully supported, open source, drop-in replacement. Today, Payara Services is home to the growing Payara Platform and Commercial Support Services, including:

The announcement that the Java EE projects would be open-sourced completely came about a year ago now, meaning the Java (EE) community would receive control over it.

Introduction

This blog explains the setup of Payara Server on MacOS systems and how you can define a specific JVM which will be used to run the server.

Microsoft Azure provides fully managed Cloud SQL databases for use by your Azure hosted cloud services. Payara® Micro is built to be the best runtime for Cloud Native Java EE and MicroProfile applications. Here’s how to rapidly create a REST web service that retrieves data from an Azure SQL Database and returns it as JSON.

Did You Know?

It seems like Microservices architecture is almost everywhere these days. For a long time, I used to have a feeling that many people talked about it but very few use it. So I decided to find out how to get the most out of Microservices. I've studied this architecture a lot, experimented with the technology created specifically for Microservices and talked to other people who knew more than me. This how I've met some incredible people. And it's also a reason why I've joined forces with Reza Rahman and Ivar Grimstad to create a Hands-on Lab about our findings, which we'll present at Oracle Code One this year.

Introduction

With the rise of the micro-service architecture, we have seen also a shift from SOAP to REST as the means of exchanging data between parties. REST and JAX-RS are gaining a lot of popularity outside the micro-service world, also.

Azure Container Instances allow you to rapidly deploy containers to the Microsoft Azure cloud without having to manage virtual machines and the corresponding infrastructure. Container Instances can be used to rapidly deploy Java EE and MicroProfile applications using Payara Micro as the underlying platform for your Cloud Native applications.

The Payara Platform is perfect for deploying Jakarta EE and MicroProfile applications on Microsoft Azure. One rapid option for deploying on Azure is to use Azure Application Services, especially Web App for Containers. The WebApp for Containers service allows you to rapidly deploy production Payara Micro applications onto Azure in seconds, allowing both rapid horizontal and vertical scaling on demand.

Payara Serverの管理タスクで最も多いものの1つは、他のWebサーバーと同様に、HTTPプロトコルやPayara Serverへのリモート・アクセスをセキュアにするための電子証明書のセットアップです。自己署名証明書または信頼できる認証機関の署名入り証明書のいずれかをお持ちでしょうが、どちらの場合も証明書をPayara Serverのドメインに追加してセキュアな通信に用いるのはとても簡単です。

In the previous guide, we’ve seen how we can configure the Payara Platform to connect to a database and use the datasource from an application. This guide walks you through the process of building an application to store and retrieve data from the database.

Introduction

OpenID Connect is a security mechanism for an application to contact an identity service, verify the identity of the End-User based, and obtain End-User information using REST API's in a secure way.

Java EEプロジェクトを作成するにあたって、Eclipseにサーバーを定義してアプリケーションをIDE上でテストできるようにしておくことは重要です。生成物をビルドして手動でPayara Serverにデプロイするよりも、作業がずっとスムーズになります。

Watch this quick video to learn how to install the open (Java Development Kit) JDK 8 by Azul Systems called Zulu. A JDK is needed to write Java apps.  We'll take you step by step through the process of checking to make sure you don't already have a JDK installed through to installation of Zulu.

This debugging guide will help you to diagnose and detect the cause of errors in your application by debugging Payara Server or Payara Micro.

Follow the steps in this 2 minute video to install NetBeans IDE on Ubuntu so you can get started developing Java EE applications on Payara Server or Payara Micro. Before you start, make sure you have a JDK installed (not just the JRE).

Eclipse MicroProfile is a framework that brings innovative technology to enterprise applications. Both Payara Server and Payara Micro provide the most recent MicroProfile version as soon as possible. Along with the aim to simplify development of microservices and cloud deployment, MicroProfile is continually adopting other modern approaches and patterns like reactive programming.

A REST Service in Java EE can be created using JAX-RS. The contents of such service can be consumed using ordinary HTTP requests to a URL. URLs are typically kept simple and have a logical pattern, so it's easy to type them manually in e.g. a browser. This is different from SOAP, which essentially uses HTTP as well, but is designed to be rather complex and therefor making it not so easy to quickly test something in a browser.

If you're building a REST service, then that REST service will expose some kind of data or will allow some kind of interactions with a server. For instance, consider a Facebook REST service that allows you to retrieve your chat history. Naturally you don't want just anyone looking at that history, hence the need for security.

We are very pleased to announce that Rudy De Busscher is joining the Payara team!

JSF is a component oriented MVC (Model View Controller) framework that's a part of Java EE. It comes with a small set of basic components (widgets), a templating engine, and facilities for converting and validating input. JSF strongly builds on other APIs in Java EE. Request handling is build on top of the Servlet API, binding UI components to Java code is mostly done via Java EE's Expression Language, with the Java code being (named) CDI beans. Validation is often delegated to Bean Validation.

This article continues our introductory blog series on setting up a simple deployment group with Payara Server, carrying straight on from our last blog where we set up a load balancer for our deployment group.

Note: This blog post is an update to Creating a Simple Cluster, which was written for Payara Server 4.

Introduction

Continuing our introductory blog series, this blog will demonstrate how to set up a simple Hazelcast deployment group containing two instances. Deployment groups were introduced with Payara 5 to replace clusters. They provide a looser way of managing servers, allowing instances to cluster by sharing the same configuration whilst providing a single deployment target for all of them. See here to read more about Deployment Groups.

We are very proud to be nominated as finalists in the "Newcomer Apprenticeship Employer of the Year" category for the annual Worcestershire Apprenticeship Awards 2018.

Introduction

In this blog series, we will aim to give an overview of the basics of using Payara Server in a production scenario using Apache Web Server (sometimes called httpd) and Ubuntu. Many of the concepts described in these blogs do not rely on the tools we are using here and can be applied to other scenarios.

Our aim is to configure the following:

Payara Server 5が既にリリースされていますので、基本的な事柄をブラッシュアップするにはちょうど良い頃でしょう。これから、Payara ServerのCLIでできることをいくつか見てゆきたいと思います。

コマンドライン・インタフェース (CLI) はコマンドライン (またはターミナル) からPayara Serverをコントロールする手段であり、複数の方法でサーバーの起動、停止、編集を行うことができます。管理コンソールでも必要なあらゆる管理操作を実行することはできますが、CLIを用いると、特にヘッドレス・サーバー (GUIを持たないサーバー) を扱う場合において、あらゆる管理タスクをより素早く簡単に実行できる場合があります。

Payara Server上でアプリをテストする時、IDEと連携してアプリをテストできるようにしておくと非常に便利です (そもそも、そのためのIDEですが)。もしNetBeansを使用しているのなら非常に簡単に実現できます。このブログではPayara ServerをNetBeansにセットアップしてWebアプリを実行するための手順をご紹介します。

The 5.182 release of Payara Server & Payara Micro (Payara Platform) brings in MicroProfile 1.3. This introduces a couple of updates to some existing specifications, and three new ones: OpenTracing, OpenAPI, and Type-safe REST Client. In this blog, I’ll be covering our implementation of the Type-safe REST Client. 

Si estás creando un proyecto Java EE, es importante tener un servidor definido en Eclipse para poder probar fácilmente tus aplicaciones desde el IDE, lo que resulta en un flujo de trabajo más practico en lugar de construir el artefacto y desplegarlo manualmente en Payara Server.

W-JAX is the leading conference for Enterprise Technology, Software Architecture, Agile and Java in Europe.  We are proud to be sponsoring the "Java Enterprise Day" and will be speaking at the event as well.

When Appriss tried migrating from GlassFish 3 to Glassfish 4 they encountered problems that prevented a successful migration. Without support from GlassFish, they were simply stuck. Payara engineers assisted Appriss through a Migration & Project Support engagement to resolve all issues and migrate Appriss production GlassFish applications to Payara Server.

*Note: This blog post is an update to Load Balancing Across Payara Server Instances with Apache Web Server, which was written for Payara Server 4.

Introduction

Continuing our introductory blog series (Payara Server 5 Basics), this blog will demonstrate how to add load balancing capability to Apache Web Server and forward to our simple Payara Server cluster.

Open source software is becoming so popular most people likely use it daily without even thinking about it. For example, if you’re using Firefox to browse the internet or WordPress to publish your blog – you’re using open source tools. According to the 2017 Open Source 360 Survey conducted by Black Duck Software, 60% of businesses report an increase in their use of open source in the last year. Despite the growth of organizations taking advantage of open source benefits, there are still many misconceptions surrounding open source software. Here are 5 concerns about open source software and why they should be considered myths:

今日、マイクロサービスのコンセプトは単に新しいだけではなくなっています。DevOpsの登場、コンテナ技術ブーム、デプロイ自動化ツールによって、マイクロサービスは開発者が手掛けるアプリケーションの構造を変えつつあります。マイクロサービスはJava EE開発者にとっていかにして有効な選択肢となり得るのか、そしてPayara Microとそれが提供する完璧なプラットフォームによってどのようなメリットが得られるのかについてみてゆきましょう。

La mayoría de las aplicaciones web modernas necesitan alguna manera de almacenar datos en una base de datos. Generalmente, Oracle proporciona la mejor solución de RDBMS en lo que respecta a seguridad, soporte y escalabilidad. Oracle XE es la versión más adecuada para desarrolladores para proyectos pequeños o personales, y además debería ser compatible con la versión completa de la base de datos Oracle. Esta guía te adyudará a configurar tanto Oracle XE y Payara Server.

Cuando estás probando una aplicación para ejecutarla en Payara Server, continuamente probar la aplicación desde tu IDE es extremadamente util (ese es su proposito, despues de todo). Si estás utilizando NetBeans esto es muy sencillo. Sigue los pasos de este blog para configurar Payara Server en NetBeans para ejecutar tus aplicaciones web.

You probably already know what clustering is, but you might not know that Payara Server 5 automatically clusters. If you use Payara Server 4, you have to manually set up clustering. Payara Server 5 introduces a convenient feature called Deployment Groups. Deployment groups do exactly as the name suggests: it allows you to group a collection of instances that will be the targets of your deployment.

Webアプリケーションを開発する際における最大の挑戦の一つは、商用環境へのリリース時にアプリケーションをどのように調整すべきかを理解することです。これはJavaのエンタープライズ・アプリケーションをPayara Serverへデプロイする場合でも例外ではありません。

In this blog, which follows on from the Cloud Connectors in Payara Micro, we will explain the Microsoft Azure Service Bus connector and how to use it in Payara Server and Payara Micro (the Payara Platform).

The 5.182 release of Payara Server & Payara Micro (Payara Platform) brings in MicroProfile (MP) 1.3. This introduces a couple of updates to some existing MP specifications, and three new ones: OpenTracing, OpenAPI, and Type-safe REST Client. In this blog I’ll be covering our implementation of OpenTracing.

Open source software offers a number of advantages over proprietary software. Many businesses prefer open source options as it reduces the procurement barrier. A survey conducted by Black Duck Software and North Bridge revealed that 78% of today’s businesses already rely on open-source software for increased security and the lack of licensing fees. It is estimated that the use of open source saves businesses $60 billion (USD) annually.

In a clustered environment, it is sometimes necessary to limit to one instance of an EJB or CDI bean for an entire cluster.

 Take a look at the infographic from the Eclipse Jakarta EE Developer Survey:

When it comes to clustering and distributed computing performance, some of the challenges you have to overcome involve cache invalidation and coordination. Fortunately, both Payara Server and Payara Micro come with EclipseLink, which supports cache coordination and invalidation out of the box. This blog will explain how to configure this feature for your Payara Data Grid.  We would also like to thank Sven Diedrichsen who is the community member that created the Hazelcast cache coordination.

Recently Ondrej Mihalyi, Payara Support Engineer, spoke at the JPrime conference.  Below you will find his slides from his presentation.

A workshop given at JPrime conference in May 2018.

Have you wondered how you can improve the design of your applications to improve its performance? You probably heard that reactive design can help achieve better response time and make your applications more flexible. But you’re asking: Do I need to rewrite my applications from scratch? Do I need to learn a new framework for all that? The answer is no, especially if your application is built on top of Java EE and Java 8.

Payara® Support provided BMW Group with a smooth migration path from GlassFish to Payara® Server and Java EE 7. Knowing that Payara Services offer a guarantee of 10 years of support for the Payara Server 4.x branch ensures a stable basis for BMW Group’s applications.

Payara Server and Payara Micro 5.182 are here, the second release of the Payara Platform 5 series.

Recently I was tasked with preparing a presentation on an update to Jakarta EE and Eclipse MicroProfile® and it got me thinking about the organisation and structure involved in this huge effort to transform Java EE into a truly open source standard under the Eclipse Foundation. While organising my thoughts I put together a picture showing the structure and tensions of this undertaking to help people understand what various groups do and perhaps how better to get involved. The structure and governance is evolving as I write this so I may not get everything right. 

Did You Know...?

Payara Server Comes with a Domain Pre-Configured for Production use Out-of-the-Box!

When creating a Java EE application it is important to deploy and test it on a server that is as close to the target production environment as possible. If you use Maven in your project, it is possible to do so using the Cargo plugin, which allows you to deploy an application to an instance of Payara Server either locally or remotely. A complete example is available at https://github.com/payara/Payara-Examples/blob/master/ecosystem/payara-maven/pom.xml.

Avanzando más nuestra serie de blogs de introducción, esta entrada mostrará como puedes escalar de forma dinámica tu cluster, y como Payara Server maneja la conmutación por fallas entre miembros del cluster.

See here for the original version in English language.

La conmutación por fallas es la habilidad de continuar proporcionando acceso a nuestro sitio web o aplicación en el caso de que un servidor falle. Es una parte importante de un servicio que goza de alta disponibilidad, cuyo objetivo es minimizar los tiempos de inactividad a lo largo de tu infraestructura de servicios.

Recently Gaurav Gupta (Principal Developer at Payara) made this presentation at the Great Indian Developer Summit in Bangalore.  

One of the concerns businesses commonly have when considering open source software is whether or not support will be available for questions and problems. iTAC Software AG provides internet-enabled information and communication technologies for the manufacturing industry and had been using Oracle GlassFish 2.1 in 2008 for their customers. Over time, they had some issues with customers requesting fixes and security updates for the application server. Unfortunately, the GlassFish Open Source Edition didn’t provide the fixes, so iTAC decided to look for another open source application server option that would include security fixes and support.

In this short introductory demo we will show you how to start Payara Micro and demonstrate how simple it is to use its dynamic clustering feature.

Back in 2016, we wrote about the importance of automation in taking applications from development to production with Payara Server. Since then, there have been a lot of changes both in Payara Server and Payara Micro and the wider tech landscape.

In this video tutorial, we'll be giving you a visual and narrative guide on how to get started with Payara Server. 

Introduction : 

Java EE Security API (JSR 375) :

The Java EE Security API 1.0 is a new spec for Java EE 8 that aims to bridge some of the gaps that have traditionally been left unspecified and provides the new way to define or configure identity stores and authentication mechanisms.  

The Payara Platform stability stream releases are available only to our support customers to provide consistency, security, and stability for your production environment. The stability stream releases provide bug and security fixes to the current feature set of 5.181 and 4.181 for 12 months, with no component upgrades or new features that could potentially cause problems. If you’re in need of a secure, stable production environment, consider investing in Payara Support to receive the benefits of our stability stream releases.

There are many reasons why companies choose to invest in commercial support for Payara® Server or Payara Micro (the Payara Platform). Here we've listed the most common reasons for buying support to achieve operational and financial benefits:

In a previous blog of this series we set up Apache httpd to forward traffic to Payara Server. However, this only covers forwarding HTTP and not HTTPS. This blog will demonstrate how to secure Payara Server with Apache over HTTPS on Ubuntu.

If you've upgraded to Payara Server 5 or are considering using Payara Server in production, here are 5 production features you might not know about - but should.

It's here! The Eclipse Foundation has announced the future of Java EE with the release of Jakarta EE ; a cloud-native Java and an open source governance model. As enterprises modernize their infrastructure for cloud, microservices and containers, the technological transformation requires a new governance model that provides faster release cycles to keep pace with innovation, along with an open source, community-driven evolution of the platform.

This quick tutorial will show you how to build your next microservice with the latest version of Eclipse MicroProfile APIs.

Now that Payara Server 5 is here, it’s a good time to brush up on the basics - with that in mind, I'm going to go through a few of the things you can do with the Payara Server CLI.

Before putting any application out for public access, it’s always worth testing that it works how you expect it to (and also how you don’t expect it to!). Effective testing of applications is something you can spend a week being taught, but for this blog I’ll just cover the basics of running JUnit and TestNG tests against Payara® Server & Micro using Arquillian.

One of the new features in Payara Server and Payara Micro 4.1.2.181 and 5.181 is full compatibility with MicroProfile 1.2. In this blog, I will introduce Metrics 1.0, a new API of MicroProfile 1.2 to use with Payara Micro (and Payara Server).

There are 2 major changes happening in the Java EE world that Payara is heavily involved in: MicroProfile – an industry collaboration to define microservices APIs on top of a subset of Java EE; and EE4J – the migration of Java EE from the JCP to the Eclipse Foundation.  Also, since Payara 5 has been released, it has brought new and exciting capabilities, and the community versions of Payara Server & Payara Micro have switched from 4 to 5.  

In this webinar presented on the 1st of March 2018, Steve Millidge (Payara Founder) and Mike Croft (Payara Head of Support) give an update on MicroProfile and EE4J, explaining the initiatives’ roadmaps, aims and objectives, and show code samples on how to use MicroProfile with Payara Server. They explained the Payara Server 2018 Roadmap and what the switch from Payara Server 4 to 5 means for Payara users.

For a long time Payara, a derivative of GlassFish, could be used in Eclipse using the Oracle GlassFish Tools. With the release of Payara 5, a few problems prevented the plug-in from recognizing Payara 5, meaning Payara 5 couldn’t really be used in Eclipse. A new set of tools again makes it possible to use Payara 5 with Eclipse, along with other improvements.

We work hard to make Payara Server robust, reliable and innovative so that it's perfect for production deployments. But we never forget about the users and developers. For them, we target flexibility and ease of use in every new feature we add and every tool in the ecosystem we maintain. Our Payara Docker images are an example of it and we're happy for the positive feedback from the user community we're receiving, as well as for the constructive suggestions that help us improve user experience in the future.

It may be hard to believe in 2018, but there was once a time before Amazon Web Services. In 2006, Amazon launched what was to become the most dominant platform in cloud computing - the Elastic Compute Cloud (EC2). While there were a lot of early adopters who could see the benefits of "Infrastructure as a Service" (IaaS) style cloud computing - a notable example being Dropbox - there were many who were sceptical of the hype around the "cloud" and prompted stickers like the one pictured.

In Payara Server 5 we have introduced the concept of a Deployment Group - in this blog post, we'll explore why they are important and what they are used for.

Payara Server 5 and Payara Micro 5 are here! We've already blogged about some improvements in Payara Server & Payara Micro 5, but there are many more. 

We know you'll be excited to find that this release includes several usability improvements making Payara Server & Payara Micro's architecture even more innovative, microservices-ready, cloud-native and optimized for production deployments.

MySQL is an open-source relational database you may wish to use with Payara Server, that excels at fast reads and is commonly used as storage for a CMS. This blog will show you how to set up MySQL on Ubuntu and connect to it from Payara Server.

As part of release 4.1.2.173, new notifier integrations were developed for Payara Server for the New Relic and DataDog application performance monitoring (APM) services. Both services allow the gathering of JVM statistics, HTTP metrics and support the use of notification for critical events in the server lifecycle management. In this era of cloud services, performance monitoring is an integral part of the IT infrastructure for any organization, which is the reason integration with these services has been brought to Payara Server. This article will show how to correctly set up these notifiers to that purpose.

First quarter of 2018 will bring with it our long-awaited Payara 5, fresh out of Beta. Scheduled for a Q1 release (download the Release Candidate here), Payara 5 brings with it a host of improvements to Payara Server and Payara Micro. Bringing long-awaited upgrades to a raft of APIs, as well as a rethinking of the cluster concept, Payara 5 also brings us up to date with Eclipse MicroProfile 1.2 and the core functionality of GlassFish 5.

We are very excited about the upcoming release of Payara Platform 5! With the new Data Grid, MicroProfile 1.2 support and incorporation of the Java EE 8 reference implementations it is shaping up to be a great release. 

With the release imminent, I thought now is a good time to let people know about some of the changes taking place in Payara Release Streams and Development, and how this affects both customers and users of the community version of Payara.

It is highly likely that most people involved in the Java EE community are already aware of the open sourcing of Java EE and the move to the Eclipse Foundation. For those unaware, however, here's a quick primer:

Configuration is an important aspect of programming. However, a standard approach to it has been missing in Java for a long time. A year ago, the MicroProfile project decided to change that. I'm glad I could be part of it and help design the new API. One year later, a common configuration API aiming to set a standard is a reality, with several released versions and multiple projects that provide it. Payara Server and Payara Micro have supported MicroProfile Config API since version 4.1.2.173. We added support for Config 1.1 in version 4.1.2.174 and completed the support for all Eclipse MicroProfile 1.2 features in version 4.1.2.181. So let's summarize what's new since Config 1.0.

There have been a lot of really great updates coming out of the EE4J project recently and as far as I can see, the project is progressing nicely given the size and complexity of the undertaking.

Previously in GlassFish and Payara Server, if you wanted to monitor the status of your application's MBeans, you would have to rely mostly on external programs to capture the data. In Payara Server 174, we integrated the JMX Monitoring service with our existing notification service, meaning that you can now remotely receive monitoring data via any of our notifiers, from email to Slack.

Thanks to Sun Microsystems, Java has an open source history dating back over ten years. 

In 2006, the OpenJDK project was announced.  It took a while to remove some lingering proprietary components but, with build 53 of OpenJDK 7, we finally had a fully open source version of the JDK.  This also became the source code for the reference implementation of the Java SE standard as of Java SE 7.

Our Payara Engineers have been working very hard on lots of new features ready for our final 5.181 release! One of the key features we intend to deliver is compatibility with MicroProfile 1.2, which will include (among other things) a Fault Tolerance API.

Payara Server 5 の (おそらく) 正式リリース前の最後となるベータ・リリースには、いくつかの大きな変更が含まれており、最終的な製品が (バグがなければ) どのようなものになるのか、お分かりいただけるようなものになっています。

In Payara Server 5 we will be introducing some major changes to the way clustering is working by creating the Domain Data Grid (see documentation for more info). The Domain Data Grid will be easier to use, more scalable, more flexible and ideally suited for cloud environments and cloud-native architectures. All Payara Server instances will join a single domain-wide data grid for sharing of in-memory data like web sessions, JCache, SSO and Stateful EJBs. 

PostgreSQL is a fully SQL-Compliant relational database you can use with Payara Server and with no commercial licensing requirements it is well suited for production environments. This blog will show you how to set up a new PostgreSQL installation on Ubuntu and connect to it from Payara Server.

As we are at the start of a New Year and it is traditional to gather your thoughts and put in place New Year resolutions and plans, I thought I would share with our Community and Customers the plans for Payara in 2018.

Have you ever wondered how Micro is Payara Micro?

At first, this was a fun experiment installing a terminal app on my Android phone and playing around with some Linux commands. One thing lead to another and I ended up running a Payara Micro instance on my device! In this article, I'm going to show you exactly how to do that.

お楽しみの、喜びの、奉仕の、そして釣りの (違った、最後のは私が付け加えただけです) 季節がやってきました。そして世界中の皆様、このお休みに (訳注: イギリスはクリスマスと翌日が祝日です) Payara Server 5 の最初のベータ・リリースをお届けします。ダウンロードはこちらからどうぞ。本当は何が欲しかったのか、私は知っているんですよ。

It’s the season of joy, cheer, giving, and fish (no, I haven’t just added the last one) and so as a gift to the world we’ve just released the first Beta release of Payara Server 5 in time for the holidays - download here. I know, it’s exactly what you wanted.

Payara Micro supports Hazelcast out of the box, and can be used for clustering. This allows members in the cluster to distribute data between themselves, amongst other things. By default, Hazelcast comes with multiple ways to discover other members in the same network. A multicast discovery strategy is commonly used for this purpose; a multicast request is sent to all members in a network and the members respond with their IP addresses. Another strategy must be employed if a member cannot or does not wish to provide their IP address.

Admitting When You’re Wrong

Just recently, I have had to admit being wrong. Very wrong. Way back at the start of October, I was feeling the familiar sensation of panic and dread that only happens right before I need to give a presentation that includes a demo! In the end, there were major problems with the AV setup in the room I was allocated, so even arriving as early I could to set up didn’t give the techs enough time to hook up my laptop successfully.

Taking our introductory series onwards, this blog will look at how you set up a simple Payara Server cluster on Windows using the native remote control protocol, DCOM. We will set up two instances on Windows 10, controlled by a third Domain Administration Server (DAS) instance on Windows 7 via DCOM, and cluster them together using Hazelcast. Finally, we will deploy our trusty clusterjsp application to demonstrate how the data is being shared across our instances.

(Guest blog)

Both Payara Server and Payara Micro can cluster together and share data using Hazelcast. Out-of-the-box, there is no configuration needed, since Hazelcast uses multicast to discover and join other cluster members. However, when running in cloud environments like AWS, for example, there are a lot of things which can stop discovery being quite so straightforward. The key thing is that Multicast is not available, meaning another discovery strategy is needed; the most common generic alternative is to use TCP, but this assumes that you know at least the intended subnet that your cluster members will be in ahead of time.

Do you still think that Java EE is heavy-weight, cumbersome and doesn’t keep up with modern trends? I’ll show you that there are already production-ready enterprise and open source solutions to bring more flexibility than the traditional Java EE servers from the past. They strive to provide lightweight and extensible runtimes to power microservices, cloud deployments and reactive architectures already. Their individual efforts are naturally followed by an open collaboration within the MicroProfile project.

Further developing our introductory blog series, this post will look at how you can dynamically scale your cluster, and how Payara Server handles failover between cluster members.

Failover is the ability to continue to provide access to your website or application in the event of a server failing. It is an important part of high availability hosting, which aims to minimise downtime across your server infrastructure.

We’re very excited to announce our new Payara Team member - Kenji Hasunuma - who joined us at the beginning of November! If you've been an active Java EE & Payara community member in Japan I'm sure you recongnize his name :) 

Read along to find out more about Kenji and what he’ll be working on at Payara.

This article continues our introductory blog series on setting up a simple cluster with Payara Server, carrying straight on from our last blog where we set up load balancer on our cluster.

By clustering our Payara Servers together and balancing traffic between them with Apache Web Server we keep the benefits of having our application accessible from a single URL and gain the resilience and expansion prospects from having our application deployed across multiple instances.

Este artículo continúa nuestra serie de blogs de introducción para configurar un cluster con Payara Server, continuando desde nuestro último articulo donde configuramos un balanceador de carga para nuestro cluster.

Didn't get a chance to attend JavaOne 2017 earlier this month? You can now watch some of the conference talks online! See below for our selection of the most interesting and useful presentations about Java EE.

All JavaOne 2017 recorded talks can be found on the Oracle Java YouTube channel.

We're excited to announce that the second Alpha release of Payara Server 5 is now available for download! We highly encourage you to give it a go, test it out and let us know what further improvements are needed. 

As a Java EE developer, I sometimes envy how fast it’s possible to see the result of a code change in a running application with interpreted languages like PHP or JavaScript. With Java, it’s always necessary to rebuild the source code in bytecode, which can be then safely updated only by restarting the whole application. And all developers know that restoring the desired state of the application after a fresh restart takes time and is tedious.

A crucial component in many web applications is the use of a database. The chances of using JDBC directly or indirectly to access a relational database (through JPA or other ORM frameworks) on these applications are quite high. A common problem when dealing with relational databases is dealing with SQL queries or statements that take too much time to resolve, thus causing your application to be considered slow in producing results to the user. It's usually better to detect these issues preemptively, before sub-par performance damages your application, and Payara Server has you covered!

One of the core steps in every continuous integration process is running integration tests for your application. Unlike vanilla unit tests, integration tests allow you to assess the state of your applications or systems by testing all of its components together (modules, databases, messaging, etc.) and verifying that they work correctly as a whole unit. Needless to say, integration tests are more complex that simple unit tests, have a larger footprint, take more time and are usually saved to test full releases or major changes to implementations.

Since being introduced in the 163 release, the Request Tracing Service has allowed you to see which requests are taking a long time. However, this service will only tell you about requests once they have completed. If a thread is stuck and unable to complete you will not know about it. To resolve that problem, we added the Stuck Threads HealthCheck to Payara Server, which checks for requests that have not finished and outputs their stack trace.

As previously reported on this blog, the Request Tracing Service was improved drastically in release 4.1.1.171 and implemented the configuration of a historic trace record storing for increased productivity purposes. In addition to these changes, we also made the configuration on the Request Tracing Service in Payara Micro for the same release. These changes to Payara Micro make it simpler to configure the Request Tracing Service when starting a new instance!

Just a little over a year ago, the MicroProfile initiative was born. The community first heard about it at the DevNation conference in San Francisco on the 27th June last year. During the keynote panel, the five founding members (Red Hat, IBM, Tomitribe, LJC, and Payara) announced their collaboration and their main goal - to make it easier for developers to use familiar Java EE technologies and APIs for building microservice applications.

We're excited to announce that the first Alpha release of Payara Server 5 is now available for download! We highly encourage you to give it a go, test it out and let us know what further improvements are needed. 

The Payara Micro 173 release had a few changes which will make the lives of Docker users easier. This blog will cover the changes which affect Payara Micro in Docker,  demonstrating the following:

• Using the new Payara Micro 5 Docker image, which provides Java EE 8 features.

• Deploying applications without the targetted database being present.

• Adding library JARs from the command line.

Have you ever wondered how you can improve the performance of your applications under high load? You've probably heard that reactive design can help meet better response time and make your applications more flexible. In this presentation, I will show that you don’t need to rewrite your Java EE applications from scratch to achieve that!

The Payara Server 173 release includes a technical preview of an upcoming REST Monitoring Service, which is a new service which exposes JMX monitoring MBeans over HTTP. One big problem with JMX is that JMX monitoring uses RMI (Remote Method Invocation), which can lead to a few nightmares if, for example, you have a firewall which blocks connections over RMI ports. The REST monitoring service in Payara Server now provides a service which will be very familiar to users of Jolokia in that it makes this monitoring data available over HTTP, making the data available in a more standard format (JSON) and accessible over a standard HTTP connection.

In the official announcement published on the Aquarium blog today, Oracle revealed that it seriously considers moving Java EE to an open source foundation.

In order to make a cluster of servers appear as one server, you need to introduce a load balancer. A load balancer will accept a request, and redirect it to one of the members of the cluster depending on a given configuration. A web server such as NGINX or Apache can act as this load balancer as well as a reverse proxy, which allows the web server to load balance requests across the cluster, act as a termination point for SSL connections to reduce strain on the cluster, as well as cache server content for quicker access. In this blog, we will set up NGINX as a reverse proxy and secure it using SSL.

Back in May, we announced the 172 release of Payara Server and mentioned a preview of our Maven plugin for Payara Micro, available on GitHub. Since then, we have released the plugin to Maven Central so, to illustrate it's use, I'll be revisiting my earlier blog on another feature of Payara Micro 172 - the ability to use Payara Micro as a JMS consumer.

Eclipse MicroProfile es una especificación para un conjunto de APIs diseñadas para construir MicroServicios. Este proyecto ha existido desde hace más de un año y es algo con lo que Payara está altamente comprometido. Los lectores a los que les gusta estar al día con las noticias desde a comunidad de Java probablemente serán conscientes de como el proyecto ha progresado a grandes saltos últimamente. Está siendo un camino largo y arduo desde la versión 1.0 a la versión 1.1 de la especificación pero, en este momento, mucho ha sido desarrollado y hay multitud de APIs actualmente en desarrollo.

See here for the original version in English language.  

The Eclipse MicroProfile is a specification for a set of APIs appropriate to building MicroServices. The project has existed for over a year now and is something that Payara is highly committed to. Readers who like to keep up-to-date with news from the Java community will probably already be aware of how the project has progressed in leaps and bounds lately. It's been a long road from version 1.0 to version 1.1 of the specification but, in that time, a lot has developed and there are multiple APIs currently being worked on.

In this blog, which follows on from the  Cloud Connectors in Payara Micro, we will explain the Amazon Simple Queue Service (SQS) connector and how to use it in Payara Server / Micro.

Continuing our introductory blog series, this blog will demonstrate how to add load balancing capability to Apache Web Server and forward to our simple Payara Server cluster. 

A load balancer can redirect requests to multiple instances, primarily for the purpose of distributing incoming requests between cluster members based on pre-determined rules. This could be a simple "round-robin" algorithm, where the workload is distributed to each instance in turn, or a weighted algorithm where requests are delivered based on a pre-determined weight for each cluster member.

Continuando con nuestra serie de blogs de introducción, este blog va a demostrar como añadir la capacidades de balanceo de carga a un Servidor Web Apache y asi re-enviar las peticiones HTTP a nuestro cluster de Payara Server.

Following up from the first part of the Security Auditing  article, where we covered the audit logging,  in this part we will focus on creating a custom audit module.

Many applications, especially complex legacy ones that are packaged with a large number of libraries, may contain libraries that are also shipped with Payara Server (like Google Guava or Jackson for example). These types of conflicts can be very hard to track down and solve. Starting from the  171 release of Payara Server, there is now another solution in the toolbox which can help with resolving these dependency conflicts.

Security is always a concern you must have when implementing applications that will run in production environments. Both the JVM and Payara Server have a strong tool set of security implementations for most use cases in the industry, so you won’t have to worry about implementing your own security measures from scratch.

In this blog, which follows on from the introduction to Cloud Connectors in Payara Micro, we will explain MQTT and how to use it in Payara Micro with Mosquitto.

Hibernate is the object/relational mapping tool that handles mapping of Java classes to relational tables and Java types to SQL data type. It’s a well-known framework in the Enterprise Java eco-system since it’s being actively developed for the last 16 years.

With this article, I’m going to show the ways of using Hibernate inside a sample application – source code available here – and deploy it onto Payara Server. I will be using the latest version of Hibernate, which is 5.2.10.Final at the time of writing.

Since Java EE 6 it's possible to define data sources in a portable way.

This does mean though that the data source is embedded in the application archive. For some use cases, this is exactly what's needed, but for others it may not be ideal.

In this blog, which follows on from the introduction to Cloud Connectors in Payara Micro, we'll guide you through the process of setting up Payara Micro as a Kafka Client, which can produce and consume data from Apache Kafka.

Payara Micro 172 brings with it support for JCA adapters, meaning it can be used as a client for Java Messaging Service (JMS) brokers. JMS is a Java EE API which provides a common interface for standard communication protocols. This means that you can send and receive messages between systems in a platform and language independent way. With Payara Micro now supporting JMS, you can setup your Micro instance as a JMS client with Message Driven Beans (MDBs) to listen and respond to messages from other systems through a message broker.

At the end of April I had a pleasure to speak at the Oracle Code event in Prague. 

In the last few weeks, we have released two builds of Payara Server; our new major version 172 and third patch build of version 171 - 171.3. This is the first time we've ever released two distinct builds in the same month, so why are we doing it?

This spring's silver lining, Payara Server 4.1.2.172, a highly cloud-focused release, is now available!

Focusing on enhancing Payara Server and Payara Micro's ease-of-use in cloud environments, we've brought in new features to make working with Docker more seamless and secure, native support for SaaS monitoring solutions and a huge increase in messaging capabilities for Payara Micro! Inside this quarter's release you will find 54 fewer bugs, a host of ecosystem and cloud improvements, and an update to match GlassFish 4.1.2. Carry on reading for a summary of this quarter's changes, or check out the full release notes for a complete list of changes.

Payara Server 171 was a huge release with lots of new features and improvements on many others. We've already written about improvements to the Request Tracing service and had a guest blog about using the email notifier.

The email notifier is just one of a whole host of notifiers we now have available. A lot were added in the 171 release and more are on their way in the imminent 172 release!

The previous part of this blog showed how to take a thread dump of Payara Server. This part will go through reading these thread dumps, particularly in regard to identifying deadlocks.

Thread dumps are a useful tool for debugging an application that's running slowly, or is otherwise causing problems. A thread dump is a snapshot of what each running thread is doing at a particular moment. It allows you to see if a thread is running, waiting, or stalling. This two-part guide will show you how to take a thread dump of Payara Server, and how to get useful information from it.

In prior releases of Payara Server, it was not possible to control the maximum number of concurrent Stateless EJB instances in Payara Server. It was, however, possible to control the number of pooled Stateless EJB instances, as well as concurrent MDB instances. These features were available in Oracle GlassFish Server 3.1 and earlier but not in the GlassFish Open Source editions (3.1.2.x and 4.x).

In the current release of Payara Server (171), it is now possible to limit concurrent Stateless EJB instances that are dispatched, allowing fine-grained control of resources, limiting surface area for DDOS attacks and making applications run more smoothly and efficiently.

This quick vlog shows off a few of the recent features and changes we added to Payara Micro in the 171 release. In it, we’ll cover sending asadmin commands to Micro instances from the DAS, how config changes in a pre-existing Payara Micro domain now get packaged up when creating an Uber JAR, as well as a couple of quality of life changes we’ve added.

Continuing our introductory blog series, this blog will demonstrate how to set up a simple Hazelcast cluster of two instances.

In contrast to a development environment, where a single server is enough to act as a "proof of concept", in production it is usually necessary to look at reliably hosting your application across multiple redundant hosts to guarantee a reliable service and allow for future scaling. With Payara Server, it is possible to easily create and add instances to clusters using Hazelcast, making configuration of a distributed application a breeze.

Continuando con nuestra serie de introducción, este blog va a demostrar como configurar un cluster sencillo de dos instancias mediante Hazelcast.

Most modern-day web applications need some way to store data in a database. Oracle arguably gives you the best RDBMS solution when it comes to security, support, and scalability. Oracle XE is the version that is most suitable for developers for small or personal projects, and should also be compatible with the full version of Oracle database. This guide will walk through the configuration of Oracle XE, and how to configure Payara Server to use it.

We’re very excited to announce two new Payara Team members - Arjan Tijms and Gaurav Gupta, who joined us last week!

 I'm sure some of you recognise their names - both Arjan and Gaurav are passionate Java EE advocates and community contributors. Arjan is a member of the JCP, Founder of the OmniFaces project and the zeef.com website; while Gaurav is a NetBeans Dream Team member and a creator of Jeddict ( formerly known as JPA Modeler).

Read along to find out more about Arjan and Gaurav and what they’ll be working on at Payara.

If you are creating a Java EE project, it is important to have a server defined in Eclipse so you can easily test your applications from the IDE - a much smoother workflow than building an artefact and manually deploying to Payara Server!

Since being introduced as a technical preview, the Request Tracing Service has been improved and polished to meet production quality requirements. In the latest Payara Server version 171, it was extended to allow tracing of more request types and more events that happen during the requests. It can also remember traces of the slowest 20 requests for viewing them later, though the number stored can be increased or decreased.

When testing an app to be run on Payara Server, it can be extremely useful to be able to test your app continuously in your IDE (after all, that’s what it’s there for). If you're using IntelliJ IDEA, this is made very easy. Follow the steps in this blog to setup the Payara Server in IntelliJ for running your web apps. Note: Java EE support is only included in IntelliJ Ultimate Edition, so this blog will assume you are not using the Community Edition.

In the last part of our series on migrating away from Oracle GlassFish Server, we will look at replacing the functionality of the Performance Tuner.

When developing an application on Payara Server, it is very common to deploy directly to a local Domain Admin Server (DAS) instance, since this is the easiest and most straightforward way to test some code quickly from an IDE. When taking an application further towards production, however, it is highly likely that a domain with several standalone or clustered instances will be used across remote hosts. In this case, it will be very hard to ignore an aspect of Payara Server that may not have been obvious before this point - the concept of nodes.

This blog post will cover both what a node is and the types of nodes available with Payara Server.

Cuando se desarrolla una aplicación en Payara Server, es muy común desplegar directamente en la instancia local del Servidor de Administrador de Dominios (DAS), ya que esta es la forma más sencilla y directa para probar rápidamente las aplicaciones desplegadas en su desarrollo. Al llevar una aplicación a producción, sin embargo, es muy probable que se utilice un dominio con varias instancias independientes o en cluster que residen en múltiples servidores remotos. En este caso, sería muy difícil ignorar un aspecto de Payara Server que puede no haber sido obvio hasta ahora - el concepto de nodos.

The latest version of Payara Server extends the Notification Service with many ways how to process notifications and send them to external services.  Sending notifications as email messages to an SMTP server is now provided out of the box. It is even possible to use an account on a public email server, such as Gmail. In this guest blog, Alessio Gennari - a member of the Payara open source community - explains to you exactly how it can be done.

Lately there has been a lot of talk about microservices - a new way to develop and design enterprise applications. In this document, written by David Heffelfinger - an independent Java EE expert - we aim to cut through the hype, explaining microservices in terms that make sense to Java EE developers. 

This blog uses NetBeans 11.1. If you're using an older version, you may need to perform slightly different steps to get the same result.

When testing an app to be run on Payara Server, it can be extremely useful to be able to test your app continuously from your IDE. If you're using NetBeans this is made very easy. Follow the steps in this blog to setup NetBeans to use Payara Server for running your web apps.

In case you missed the news earlier this week - we are pleased to announce a new release of Payara Micro and Payara MicroProfile 171 to start the new year with a bang! With this new release, we have implemented substantial changes that are meant to improve the stability and usability of both 'regular' and MicroProfile version of Payara Micro. As is usual with our releases, keep special attention to our blog in the following weeks to read detailed articles on these changes and features to take full advantage of them!

For Payara support customers, LTS - Long Term Support - has been introduced for both Payara Micro and Payara MicroProfile so you can expect a full year of patch releases which only include fixes - great news for users who value stability over new features (find out more about the support services here)! 

All new changes and features introduced in this release are also included in Payara MicroProfile unless explicitly stated.

Kick-starting yet another year, we are pleased to announce our largest release yet - Payara Server 4.1.1.171. Building on a year's worth of updates and improvements, in this release, you can find 18 brand new features and over 60 new fixes and enhancements for Payara Server & Payara Micro! Given the size of the additions, look out for detailed blogs in the near future. For now, check out below for a summary of the changes in 171 release, and have a look at the full release notes.

Throughout the last year, the Payara team were tracking all the important activities related to Java and Java EE. We attended many conferences, actively participated in lots of community activities, and we helped to found a completely new MicroProfile initiative, with the aim to facilitate innovation in the enterprise Java space.

With this article I'd like to look back at 2016 to share my impressions from the past year with you and outline what we at Payara expect to happen in the Java world in 2017.

See here for the original version in English language. 

In the first blog of this series, we configured our Apache Web Server. Our next step will be to set up request forwarding to send traffic to Payara Server. If you need guidance on installing Payara Server on Ubuntu, we already have a blog post covering the installation of a JDK and Payara Server which we would recommend you read before continuing with this blog.

In the fifth part of our continuing series on alternatives for commercial Oracle GlassFish features, we are looking  at a replacement for the Oracle's Access Manager integration feature.

Let’s rewind to the first half of the year

2016 - what a year it was for Java EE! As most of you probably remember, around spring time, some worrying rumours started spreading in the Java community about Oracle abandoning Java EE. To make things worse, crucial members of the Oracle Java EE team were leaving, including Cameron Purdy, Reza Rahman, Mark Heckler and John Clingan.

In this blog series, we will aim to give an overview of the basics of using Payara Server in a production scenario using Apache Web Server (sometimes called httpd) and Ubuntu 16.04. Many of the concepts described in these blogs do not rely on the tools we are using here and can be applied to other scenarios.

See here for the original version in English language. 

In the fourth part of our continuing series on alternatives for commercial Oracle GlassFish features we are looking at the JMX Monitoring Service & the Payara HealthCheck Service as possible replacements for Oracle's Monitoring Scripting Client.

In our continuing series on alternatives for commercial Oracle GlassFish features , in this article we are looking at Hazelcast - a replacement for Oracle's Coherence ActiveCache.

As a follow up to our 'Getting Started with Payara Micro Demo', we have another introductory video for you, this time demonstrating the Payara Micro API, using NetBeans and Maven.

Below you will find a selection of the recorded talks ( in English, Spanish & Czech language) from some of the events we've had a pleasure to present at in 2016.

Today, continuing our series on alternatives to commercial Oracle GlassFish features, we will look at backup and restoring domains with Payara Server.

See here for part one of the GlassFish to Payara Server migration series: 'Migrating away from the Load Balancer Configurator Plugin' .

In this short introductory demo we will show you how to start Payara Micro and demonstrate how simple it is to use its dynamic clustering feature.

As a long-term Java EE developer, consultant and lecturer, over the years I've seen Java EE evolving into a solid, carefully thought out, flexible platform, and one of the most lightweight enterprise frameworks. Therefore I was very surprised to read so many negative and incorrect claims about Java EE in the recent Gartner report "Market Guide for Application Platforms", written by analysts Anne Thomas and Aashish Gupta. The report claims that Java EE is not lightweight, has become obsolete and hasn't kept pace with modern architectural trends. These statements are made very confidently, yet are rather surprising, especially coming from such a well-known advisory company!

In his interview for The Server Side ( TechTarget) Ondrej Mihalyi - Payara Support Engineer - discusses the benefits and challenges of transitioning to reactive programming model and how Java EE facilitates reactive development.

In the first of our series on migrating away from Oracle GlassFish Server, we will look at replacing the functionality of the Load Balancer Configurator, and its potential alternatives.

In his second interview for TechTarget, Mike Croft - Payara's Support Engineer - talks about the benefits of having a configuration standard as part of Java and Java EE. Mike is also sharing his views on how container-based technology is changing the way application servers are developed, along with how microservices are being deployed.

One of the biggest challenges when developing applications for the web is understanding how applications need to be fine-tuned when releasing them into a production environment. This is no exception for Java Enterprise applications deployed on Payara Server.

Watch the interview with Mike Croft, Payara's Support Engineer, where he discusses views on implementing and building microservices for Java EE and talks about the challenges that businesses might face when adopting microservices.

The capability to disable implicit CDI scanning was already added to the previous Payara Server releases but the default admin console setting was to enable it at deploy time. We have now made a change so that the value added to the deployment descriptor is the overriding setting and the admin console setting will be ignored.

For even more control, we have added the ability to explicitly include or exclude JARs within an Application Deployment from CDI scanning. You can now, for example, include all JARs by default and exclude some named ones, or do the opposite and exclude all by default and only include some named ones.

2016 has been a bit of a wild ride, to say the least. Lots of major things have happened politically and in popular culture. Considering the world of Java and its related ecosystems, we've seen a lot of activity too, with announcements about the delay of Java 9, the concerns raised by the Java EE Guardians (shared by many), and a largely unprecedented move in the establishment of the MicroProfile initiative.

In this three-parts article series I'm illustrating the implementation of the LDAP integration using a sample scenario: integrate Payara Server with a LDAP user directory and manage the authentication and authorization of a sample web application.

In Part 1, I showed you how to start the LDAP Server, while in Part 2  we configured the LDAP realm. Now you are probably wondering how to get the user’s information (first and last name, email address, etc.) that resides in the LDAP server. Unfortunately, the JAAS API doesn’t offer any standard mechanisms to access this user attributes in the directory tree. But there are other options available:

Another quarter, another release! After an eventful 2016, November brings with it the final release of the year for Payara Server. This year, we've seen new services like Request Tracing and Health Check added, as well as the Slow SQL logger and SQL Trace Listeners. Revisiting the version of the documentation from 1 year ago and comparing the amount we have added since then is, frankly, astonishing!

Despite a bumper year for both new features and bug fixes, work continues apace! Below is a short summary of some of the things to look out for in a release that caps an incredible 12 months.

See 'Part 1 - Configuring the LDAP Server' here.

In this three-parts article series I will illustrate the implementation of the LDAP integration using a sample scenario: integrate Payara Server with a LDAP user directory and manage the authentication and authorization of a sample web application.

If you work in an organization with a robust IT department, it's very likely that you are using a LDAP server to handle your user directory information. You probably have to follow some general guidelines dictating that all web applications deployed within the organization’s infrastructure must access this user directory; and must authenticate and authorize the users that will interact with them. This is a very common scenario nowadays.

JavaOne 2016 might be a thing of the past now but the talks presented there are still very relevant! Luckily for those who couldn't make it to the conference in San Francisco in September, a lot of the presentations were recorded and are now available to watch on-line (see a full list here).

Here's our selection of the most interesting, recorded JavaOne 2016 talks that focus on Java EE. 

It is relatively common for applications to need additional configuration files outside of what is provided in Payara Server or Payara Micro. If you are used to using a custom security realm in Payara Server, for example, it may not be immediately clear how you can use the same file with applications deployed to Payara Micro.

In order to fine tune a HTTP listener, the Payara Server administration console provides the means to configure a wide range of options. Besides the basic configuration available for a HTTP listener in the HTTP service section, it is also possible to set low-level configuration details in the HTTP tab of the same network listener in the Network-Config section.

As you probably know, Payara Server was created as an effort to fill the gaps that Oracle left when they dropped commercial support offerings for Glassfish Open Source Edition 4.x versions. However, our goal at Payara Services is not only to fill these gaps in support, but to strengthen the Community around Payara and GlassFish as well. For this to happen, we encourage all Payara Server & Payara Micro users to contribute to the Community - and there are a couple of ways to do so.

We've recently moved the documentation for Payara Server and Payara Micro from its original home in the GitHub project wiki. In doing so, we've altered the structure of the pages and introduced new ways to contribute through the GitBook platform.

The video tutorial by the Payara Support Engineers Mike Croft and Ondrej Mihalyi, presented at the JavaOne 2016 Conference in San Francisco last week is now available to watch online!

With this article, I'm going to integrate Payara Embedded with Arquillian by having it defined inside a sample Maven based application - source code available here - which employs an integration test implemented by the Arquillian framework.  You can also find our previous post about Arquillian and the Payara Server available here, but this time I’ll take it one step further and move onto the IDE side. In this example, I will execute tests just like any JUnit test; meaning the test will be executed directly through the IDE with help of a right-click. I will also configure Payara Embedded as the Arquillian container inside the IDE.

Back in June we announced MicroProfile with RedHat, IBM, Tomitribe, LJC and SouJava and Microprofile.io was launched as a location for community collaboration on Enterprise Java Microservices. In the announcement each of the vendors promised to have a MicroProfile runtime ready and available in time for JavaOne. Well  after much beavering away here in the Payara Engineering team we have just pushed onto Maven Central our 1.0 release of Payara MicroProfile.

Have you ever wondered whether your application is slow to respond to requests? Which requests take the longest to respond to? And what you can do about it? Payara Server aims to provide the best tooling you would need to identify performance issues, identify their causes and help you solve them. One part of this tooling is the new Request Tracing service, available in Payara Server and Payara Micro from version 163 as a technical preview.

Any project, large or small, would ultimately like to follow industry best practices, such as continuous deployment.  In order to support this, applications must be deployed early and often.  This, in turn, triggers downtime and the users get affected by it because they could be logged out of the website, or worse, their work gets lost because the application's intermediate state is not saved - never mind the actual downtime during the application deployment process.

Rolling upgrades solve this problem in an efficient way!

TIP: Don't deploy any apps to the DAS in production!

Why?

As is the case with all my stories, this one began at a customer site. They had an old app they were migrating from GlassFish 3.1.2 to the latest version of Payara Blue. They'd called me in because they wanted to benchmark performance of the new version of Payara Blue on AIX against their existing GlassFish 3.1.2, also on AIX, as well as against a recent version of JBoss (I'm unsure of the version, though I know it was deployed on Windows).

Payara Micro is packed with a lot of the APIs that come with Payara Server Full Profile, and even more features targeted at clustered deployments. Now, since version 163, it is also possible to use persistent EJB Timers, which are stored across your micro instances inside the distributed Hazelcast cache.

When Payara Server has been logging monitoring data to the server log for a short while, the metrics that Logstash outputs to Elasticsearch can be visualised using Kibana. In this blog post, we will create a date histogram displaying used heap memory as a percentage of the maximum heap memory.

 Following the first part of this series of blog posts, you should now have a Payara Server installation which monitors the HeapMemoryUsage MBean and logs the used, max, init and committed values to the server.log file.  As mentioned in the introduction of the previous post, the Monitoring Service logs metrics in a way which allows for fairly hassle-free integration with tools such as Logstash and fluentd.

Often, you might find it useful to store your monitoring data in a search engine such as Elasticsearch or a time series database such as InfluxDB. One way of getting the monitoring data from your server.log into one of these datastores is to use Logstash.

This blog post covers how to get monitoring data from your server.log file and store it in Elasticsearch using Logstash.

(note: there is an updated version of this blog post available here https://blog.payara.fish/making-use-of-payara-servers-jmx-monitoring-service-part-1-setting-up-the-service)

 With the release of version 4.1.1.163, Payara Server includes a JMX Monitoring Service (technical preview) which can be used to log information from MBeans to the server log. Using the Monitoring Service, you can monitor information about the JVM runtime such as heap memory usage and threading, as well as more detailed information about the running Payara Server instance. The information is logged as a series of key-value pairs prefixed with the string PAYARA-MONITORING:, making it easy to filter the output using tools such as Logstash or fluentd. 

In this blog series we're going to show you exactly how to use the new Payara Server Monitoring Service. First, we'll take a look at setting up the service - let's get started!

As we enter the third quarter of the year, that can only mean one thing: Payara Server 163 is here! With this release, we’ve managed to cram in 44 bug fixes, 34 enhancements, 6 new features and 6 component upgrades. One of these new features is the tech preview of our new Request Tracing service, which I’ll explain in more detail below.

As part of the new features introduced with the release of Payara Server 162, you can now form a cluster of Payara Server instances using the concept of Hazelcast “Lite Nodes”. This can help you create more flexible cluster topologies.

The new Java Magazine is out now, featuring a lot of useful articles about enterprise Java - not so much Java EE as a platform, but individual services that can be useful as part of a larger solution. See below for an introduction to my article on Custom Servlet Authentication Using JASPIC, also featured in the magazine. 

Take a look at this quick demo to see some of Payara Micro's  dynamic clustering capabilities. I'm running the demo without any extra tools, just Payara Micro itself. To show how Payara Micro dynamically rebalances the cluster, I used JCache and Payara Micro's --autoBindHttp feature.

Payara Server 163 is about to be released in a couple of days, as usual with many improvements and bug fixes. Although it cannot match the previous release in the number of new features, the list of improvements and fixes in Payara Server 163 is already longer than in the current release!

Access Configuration

Now that the ForgeRock tools have been installed, we will configure them with some basic access configuration. First, proceed to login to the OpenAM application (context /openam) with the amadmin user, and the application will show you the current realm configuration for your domain:

The recording of the Payara Team Q&A session, broadcasted live on Wednesday the 20th of July, is now available to watch on YouTube!  Payara Engineering and Development Team answered questions from the community (listed below) and discussed Payara Server, Payara Micro, future releases, upcoming features, best practices, use cases and more.

In this short video recap, Ondrej Mihalyi ( @OMihalyi )- Payara Support Engineer – gives you an overview of the Payara Server 162 Release Notes. Tune in to find out more about the most useful developer and operations features in Payara Server and Payara Micro 162, Payara Documentation update, new Docker images, new demos, how to contribute and more.

Introduction

Today, one of the most important concerns for enterprise applications is to implement robust security mechanisms that allow developers and operation staff to easily integrate applications in a stable infrastructure and allow their users to interact with them in a seamless way. While many developers prefer to implement their own security mechanisms or use third-party libraries, a good alternative is to use already established products that handle authentication, authorization, confidentiality, identity, and entitlement on behalf of already developed applications.

Do you want to find out more about Payara Server, Payara Micro, future releases, upcoming features, bug fixes, our view on the latest industry trends, use cases or customer stories? Just post your questions in the comments below - our Payara Engineers' Panel including Mike Croft ( @croft), Ondrej Mihalyi (@Omihalyi), Fabio Turizo, Andrew Pielage ( @Pandrex247 ) and Dominika Tasarz ( @Dominislawa - event host) - will answer them during the 1-hour live Google Hangouts session!

Application server clustering provides a means to make application infrastructure more robust and perform better. However, it is often very inflexible and even a small change in the cluster topology can involve serious maintenance costs. Payara Server supports a new way of clustering based on Hazelcast, which brings much more flexibility, decreases maintenance costs and adds the benefit of JCache support out of the box.

GlassFish has traditionally used Project Shoal to power its clusters. Since Shoal is no longer actively maintained, Payara Server intends to replace Shoal with Hazelcast, which has the added benefit of being JCache compliant.

Today at the DevNation conference in San Francisco, Payara’s Mike Croft appeared onstage during the Keynote, joined by Mark Little from Red Hat, Alasdair Nottingham from IBM, Theresa Nguyen from Tomitribe and Martijn Verburg from the London Java User Group to announce a new community collaboration called MicroProfile. 

The goal of the MicroProfile initiative is to make it easier for developers to use familiar Java EE technologies and APIs for building microservice applications.

Payara Micro allows running web applications in a self-contained and easy way. Since the release of Payara Server 162, there is a simple way to generate an “Uber” JAR that bundles the contents of a WAR file and the classes and resources that compose Payara Micro!

The HealthCheck Service provides automatic self-monitoring in order to detect future problems as soon as possible. The HealthCheck Service was introduced in Payara Server and Payara Micro version 161 and some new metrics have been added in version 162.

All the functionality of the HealthCheck Service that is available in Payara Server is also included in Payara Micro. However, as Payara Micro differs in some concepts from Payara Server, the usage and configuration of the HealthCheck Service is slightly different. In this post, we will focus on how to use it in Payara Micro.

Payara Micro 162   can now deploy your artifacts stored in Maven repositories simply by providing the GAV coordinates. This should provide another option for continuous delivery scripts! 

A year ago, we brought you our first Docker images. Today, we have updated them with a few changes and refinements.

For those already familiar with Docker, here are the key points:

Since Payara Server is on a regular and frequent release cycle, we get a lot of questions on how to upgrade to the latest version while maintaining existing domain configurations.

The answer to the question of “how do I upgrade?” is always “it depends”, because everyone’s situation is going to be slightly different. This blog will cover some of the most straightforward ways which should apply in the majority of cases.

Recently, I was working with a customer on a production deployment of Payara Server and the topic of disaster recovery and backups arose. It seemed like a useful topic to blog about and share my thoughts with the community.

If you've read my interview with JAXenter, you already know  that I very much disagree with labelling Java EE as heavyweight - simply because it is not true! The latest servers from most of the Java EE vendors have been re-architected to be very light-weight on resources including memory, cpu and disc footprint. We recently did some testing of microservices implementations and many of those come in at under 50MB of RAM to run Java EE based microservices. Also, installation and configuration has been streamlined and many of the microservices versions of the products require no installation.

In this interview for JAXenter.com , Steve Millidge, the Founder of Payara and speaker at JAX 2016, talks about how to use CDI annotations in your Java EE applications, when to use which annotations, and what is automagically happening under the covers.

Steve also tells us exactly how heavyweight Java EE really is, explaining the repercussions and solutions.

Starting with JSF 2.3-m05 we can take advantage of a brand new feature - register a WebSocket push connection in client side. Thanks to the JSF team (especially to Bauke Scholtz (aka BalusC)) this feature is available in today milestone via <f:websocket/> tag.

In this post, let's see a minimal usage of <f:websocket/> tag.

One of the most exciting new features in the Payara Server 162 release is the Asadmin Recorder - a tool especially useful for the Operations Teams! 

Asadmin Recorder allows you to create runnable scripts of asadmin commands that mirror configuration done in the administration console.  Have a look at our video walkthrough below for a quick overview of this new Payara Server feature.

Once you have developed applications on Payara Server and moved these applications into a production environment, control will pass over to your Operations Teams. This guide will introduce some features of Payara Server that you may not know about, which are especially useful for the operations teams.

The second release of 2016 is finally here! Payara Server 4.1.1.162 is our biggest release yet in terms of sheer number of bug fixes and new features. One of the biggest things isn't actually a new feature of Payara Server but a newly rehosted documentation, and it's where you'll find the full release notes for this version. 

In the first part of this 'Introduction to Payara Scales' blog, I will give you an overview of the architecture for a Payara Scales cluster and a load balancer upfront, using Amazon CloudFormation and Amazon EC2.

After you've got familiar with administering Payara Server, having configured your domain and deployed your applications, you might find it useful to get information on features supporting maintenance of your domain in the longer term.

In this quick blog I will explain how you can install Zulu JVM and run Payara Server on it. I will be using Ubuntu 14.04 LTS but it shouldn’t require many modifications in case you prefer using other Linux-based platforms.

En este pequeño blog voy a explicar como puedes instalar la JVM (Java Virtual Machine) Zulu y ejecutar Payara Server en ella. Para esta demostración voy a utilizar Ubuntu 14.04 LTS, pero en caso de que prefieras usar otras plataformas basadas en Linux, no se requieren muchas modificaciones.

Taking an environment from development through to production is often an afterthought and can all too often be too far down the list of priorities. Initially, there may not be any obvious problems or issues with manually configuring a new production environment to match an existing one in development or test. As some customers I have visited have found, however, this will only lead to bigger and bigger inconsistency between platforms with ad-hoc changes causing different environments to diverge.

Recently I attended as a speaker at my second jDays, a great conference in a great venue in Gothenburg. jDays is a fantastic conference as it is small enough to easily meet people and network and discuss tech, while at the same time big enough to run multiple tracks so there is always a session on that you’ll be interested in. 

Payara Server makes it possible to deploy multiple versions of the same application at the same time. While only one of the deployed versions can be enabled and running, all the other versions remain on the server and you may enable them at any time to immediately switch the running versions.

One of the most common administration tasks with Payara Server, as well as with any web server, is to set up certificates to secure either HTTP protocol or remote access to Payara Server administration interface. You might have a self-signed certificate or a certificate signed by a trusted authority. In both cases it is pretty easy to add them to a Payara Server domain and use them to secure communication channels. 

Payara Server comes bundled with OpenMQ, which implements the Java Message Service (JMS) standard.

For simple messaging scenarios, it is convenient to use embedded OpenMQ broker, which is available by default. However, this embedded OpenMQ is running inside the JVM instance of Payara Server. This implies that whenever one of them needs to be restarted, the other one gets restarted too.

Of course, as responsible developers, we all thoroughly test our code and therefore our applications never need troubleshooting; it's everyone else's code that goes wrong.

So what do we do when the inevitable happens?

Payara Server y NetBeans son perfectos para crear servicios web RESTFul y aplicaciones web!

See here for the original version in English language. 

En este corto video, voy a mostraros como de fácil es crear un servicio web RESTFul utilizando Payara Server con NetBeans.

Payara Server & NetBeans are perfect for creating RESTful web services and web applications!

In this short video, I show you how easy it is to create a ‘hello world’ RESTful web service using Payara Server with NetBeans.

In this blog post I will provide a brief introduction to JASPIC and then take a walk through setting up a basic demo using JASPIC to secure a simple web application in Payara Server.

Luckily for those who couldn't attend JavaOne 2015  in San Francisco last October, you can now watch most of the conference presentations on-line. Here's our selection of the JavaOne 2015 talks using Payara Server and Payara Micro.

Opening our new Payara Updates video series, Mike Croft (@croft) - Payara Support Engineer – gives an overview of the Payara Server 161 Release Notes, highlighting a couple of great community contributions to this release. Mike also mentions some of our plans for the future update videos, so tune in if you want to find out more!

Siempre es un buen momento para repasar lo básico, con esto en mente, voy a comentar algunas de las cosas que puedes hacer con el interfaz de línea de comandos, Command Line Interface, de Payara Server.

One of the lesser known features and key benefits of Payara Server is that it provides huge flexibility when architecting topologies for High Availability and Scalability. Utilising the embedded Hazelcast Data Grid for web session and JCache clustering brings the potential of many different topologies for scale out.

This hot fix removes an arbitrary file read exploit that allows an attacker to read the content of any file on the server hosting the DAS. This exploit attacks the administration console with a specific string, bypassing secure administration and any required login details. Therefore, if the administration console is not publicly accessible, and Payara Server is running under a restricted user (as per best practice), then the risk is minimised.
