We'd like to invite you to join us for the Payara Platform October 2020 Roadmap Update on Thursday, Oct 22, 2020 03:00 PM BST / 10:00 AM EST.

If you're running your applications using Eclipse GlassFish, or one of its older iterations, you may have encountered one of the following common issues that hamper the productivity of your application development and overall server management in some capacity:

Microservices architecture allows developers to apply best practices for larger systems learned over time with containerized Jakarta EE (Java EE) application deployments in any environment: on premise, in the cloud, or hybrid.  Using Payara Micro in the cloud offers benefits ranging from reduced expenses, seamless integration with cloud platforms and tools for management and automation, to automatic and elastic clustering. 

We're happy to announce that Payara Platform Enterprise 5.21.2 (request here) Edition is out today!

All companies are software companies, and businesses will always experience the challenge of keeping integrations between users and applications scalable, productive, fast, and of high quality. To combat this, cloud, microservices, and other modern solutions come up more and more in architectural decisions.

Here is the question: Is Java prepared to deal with these diverse concepts in a corporate environment?

Yes, and to demonstrate how Jakarta EE and Eclipse MicroProfile work very well and in the cloud, the Payara and Platform.sh will work together on this webinar. Watch and make your conclusions.

Payara Server was created in 2014 as a fully-supported drop-in replacement for GlassFish. As Payara Server developed, its popularity has grown quickly among the community due to an open and responsive development team, a regular release cycle, and the introduction of crucial production enhancements that were never available in GlassFish. Migrating from GlassFish to Payara Server can be simple and straightforward - and we make it even easier with migration guides and a growing library of migration resources.

I hope you enjoy this month's catch. You may notice I made an effort to try and search for content by authors we had not featured before (and are a little less known), as well as including a few of our prolific favourites. There was also a slight lean towards Kubernetes themed content this month as well.

In this blog you will find a curated list of some of the most interesting news, articles and videos from the last month. Can't wait until the end of the month? Visitour Twitter page where we post all these articles as we find them! 

Payara Platform Enterprise Edition is designed to run mission-critical Jakarta EE applications in production environments with increased stability and security. Payara Enterprise is fully supported and offers access to production-oriented features and developer tools - including a wide range of supported IDE extensions, build tool plugins, test containers and connectors available under the Payara Enterprises repository.

Payara Enterprise now supports ARM architecture, along with OpenJ9 and Amazon Corretto JVMs!

We have been busy bringing new functionality to the monitoring console. The newest Domain RAG Status feature coming in the August 2020 release offers better integration of the Eclipse MicroProfile Health checks. This article will go into the details of the integration and showcase how it can be utilised in the monitoring console.

New in the Payara Server 5.2020.4 release (August 2020), RMI calls to an EJB hosted on Payara Server from a Java SE client will now have the active Span Context automatically propagated to the server, with a counterpart server-side span being created as a child of this client call. This fills in a gap in our existing Request Tracing service, and comes with the added benefit of allowing a user to propagate key:value pairs from a Java SE client to Payara Server (or simply from server to server) in a request as OpenTracing baggage items - of particular interest to those who utilise Context Propagation or similar features in other application servers.

We're happy to announce that Payara Platform Community 5.2020.4 (direct download here) and Payara Platform Enterprise 5.21.1 (request here) Editions are out today!

With this patch release of Payara Platform Enterprise, we focus on stability and consolidation of the software components delivering value around your Enterprise subscription. Meanwhile, the Payara Community Edition introduces some security, stability, and monitoring improvements of features for testing, such as Remote EJB Tracing and Monitoring Console Domain RAG Status & Developer Metrics. Read more below to find out the details!

The focus of the recent improvements for Payara Monitoring Console in the 5.2020.4 release has been on configuration sharing and ease of usage. Here's a brief overview of a couple of new features available in the Monitoring Console.

Both Payara Server and Oracle WebLogic servers can be considered classic application servers, but in addition to running classic Enterprise applications on Payara Server, it also complies with more recent trends in the industry. In this blog, we'll cover 6 technical reasons why you should choose Payara Server over WebLogic:

Payara Server Enterprise 5 is a cloud-native middleware application platform supporting mission critical production systems with reliable and secure deployments of Jakarta EE (Java EE) applications on premise, in the cloud, or hybrid environments. If you’ve been running GlassFish in production but are struggling with a lack of support and infrequent application server releases, bug fixes, and patches - or you want to run on JDK 11, you’ll benefit from migrating from GlassFish to Payara Server. 

In this new video you can watch Payara CEO and Founder Steve Millidge talk about the plans we have for the Payara Platform, in the near future and beyond; and how this ties in with Jakarta EE 9/10/+ and Eclipse MicroProfile. 

I hope you enjoy the article and news round up this month, as usual their was a lot to talk about in the Jakarta EE & MicroProfile space, as well as Java as a whole. You may notice a slight shift in emphasis towards Security themed articles this month which I hope you find useful.

In this blog you will find a curated list of some of the most interesting news, articles and videos from the last 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 tutorial, I will explain how to create, run and debug a Payara Micro application in Visual Studio Code. (If you're interested in learning more about using Payara Server in VSCode, please checkout ourprevious blogs.)

With an estimated third of the global population under “lockdown” during the peak of COVID-19, organizations were forced to rapidly shift to remote working environments - prepared or not. The unplanned change in operations put significant pressures on existing systems and tested business continuity plans.Check out this whitepaper with the results of a recent survey of the community to learn about COVID-19 business challenges and how open source technology has helped. 

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.

If you just want a quick answer to which Payara versions support HTTP/2 on which JDK version, jump ahead to Does Payara Server Support HTTP/2?

We're happy to announce that Payara Platform Community (5.2020.3) and Payara Platform Enterprise (5.21.0) Editions are out today!

The Enterprise Release (request here) features 13 improvements, 11 bug fixes & 1 component upgrade, while the Community Release (direct download here) includes 11 bug fixes, 9 improvements and 1 component upgrade. 

Here's some detail of what's new in the Community & Enterprise Editions:

The Payara Platform 5.2020.3 release (coming soon!) introduces major refactoring and architectural changes to the underlying implementation of MicroProfile OpenAPI 1.1.2.

The goal of the OpenAPI specification is to provide a standard format for documenting REST API services which is extremely useful, as it follows a standard and it can be used in a range of tools such as those provided by the Swagger suite. These let you do all sorts of things such as design, edit, and test a REST API documented by an OpenAPI document.

本日、Payara Platform Community (5.2020.3) および Payara Platform Enterprise (5.21.0) Editionsのリリースをお知らせできることを嬉しく思います。

Enterpriseリリース (こちらからお問い合わせください) は13の改善、11のバグ修正、1コンポーネントのアップグレードを含みます。また、Communityリリース (こちらから直接ダウンロードできます) は11のバグ修正、9の改善、1コンポーネントのアップグレードを含みます。

では、Community & Enterprise Editionsの最新情報について、いくつか詳しくお伝えします。

Recently we rebranded the Community and Enterprise Editions of the Payara Platform to clarify and strengthen the differences between our Community software and our Enterprise subscriptions for customers.

Securing your application is a very important aspect of the development of your application. You not only need to make sure that the application has the intended functionality but also that this functionality can only be executed by the appropriate people. You not only need to make sure that updates to data are restricted to the correct people, but it is also important that end users only see data they are allowed to see. And in case of sensitive data, this is even more important.

As usual, it was a busy month. With some big announcements from Microsoft and Oracle (see News section), the Jakarta EE 9 release, as well as Developer Survey results published by JetBrains, Eclipse and Snyk. We also had a major release ourselves. Sifting through the content I had a sense of renewed optimism and progress in the Java community. 

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

The runtime image of Payara Server consists of over 400 modules. Half of these do not come directly from the Payara codebase, but are various third-party APIs, their implementations and helper libraries. How do you choose the correct versions of your application's libraries so they are not in conflict with the ones in the server runtime?

As a leading contributor to Jakarta EE, we're happy to announce the Eclipse Foundation Jakarta EE 9 Milestone Release and the results of their 2020 Jakarta EE Developer Survey. 

The Jakarta EE 9 Milestone Release demonstrates the significant progress made toward the final release later this year, and offers an opportunity for the industry to try the new namespace and start migrating their frameworks. 

The 2020 Jakarta EE Developer Survey features responses from thousands of enterprise Java developers around the world, with results showing significant growth of Jakarta EE 8 use and interest in cloud-native Java.  The 2020 Jakarta EE Developer Survey results can be downloaded in their entirety here.

We'd like to invite you to join us for the Payara Platform Release Overview Webinar on Wednesday the 24th of June at 4pm BST / 11am EST.

As the recent June release (download here!) marks the first official release since splitting our product into two separate software editions, Payara Platform Enterprise and Payara Platform Community, you may notice the versioning has been updated.

We're happy to announce that Payara Platform Community (5.2020.2) and Payara Platform Enterprise (5.20.0) Editions are out today! The Community Release includes 28 bug fixes, 13 improvements, 3 new features, and 5 component upgrades. You can download it here! 

Here's some detail of what's included in the 5.2020.2 Community release:

With the June Payara Platform releases, Payara Platform will support version 3.3 of the MicroProfile (MP) standard. This blog summarises what changed since 3.2 and how this affects the Payara Platform.

Starting with our June 2020 release (coming soon!), we’re rolling out separate editions of Payara Server and Payara Micro - collectively known as the Payara Platform.

本日、Payara Platform CommunityおよびEnterprise Editionの出荷をアナウンスできることをうれしく思います。Communityリリース (5.2020.2) には26個のバグ修正、13個の改善、2個の新機能、そして5コンポーネントのアップグレードが含まれます。こちらからダウンロード可能です。

5.2020.2リリースに含まれる機能の詳細をいくつかご紹介します。

来たる2020年6月のリリースから、Payara ServerおよびPayara Micro (以下Payara Platform) を2つのエディションに分けて展開いたします。

Alot went down in May! notably Java's 25th anniversary and a whole swathe of articles, webinars and podcasts that went with it! It felt like there was a webinar everyday!

Below you will find a curated list of some of the most interesting news, articles and videos from the last 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 short video Rudy de Busscher demonstrates how to use MicroProfile OpenTracing with Jaeger in combination with Payara Micro.

In this short video Rudy de Busscher shows how to connect MicroProfile Metrics with Prometheus and Grafana to produce useful graphics and to help investigate your microservice architecture.

In this short video, Rudy de Busscher demonstrates how to use MicroProfile Config with etcd.

For some time now there has been an undeniable growth of interest for Microservices. The core concept itself, however, is not that new.

We are continuing to change and improve the way we build and report our future platform releases through the introduction of the Open Roadmap.

Migrating from GlassFish to Payara Server can be a simple and straightforward process, made even simpler with the help of our 'GlassFish to Payara Server Migration Guide'.

Payara Micro is a lightweight middleware platform for containerized Jakarta EE application deployments, but it still provides a lot of APIs and functionality for developers. On top of all Jakarta EE Web Profile APIs, Payara Micro also supports a additional Jakarta EE APIs, and it also provides the same MicroProfile, Payara, and JCache APIs as our complete application platform, Payara Server. In this article, we’ll show you how to make use of Jakarta Messaging (JMS) in Payara Micro to send and receive messages to and from a JMS broker.

Migrating applications from WildFly to Payara Server can be a simple and straightforward process because both servers rely on the Jakarta EE (Java EE) specifications. However, there are differences in many areas because many Java EE APIs in WildFly and Payara Server are implemented by different components. Moreover, the configuration of certain aspects like external resources, high-availability and deployment is not covered by any specification and is, in fact, very different in both servers. Although Payara Server offers similar features as WildFly, they are often based on different technologies and concepts, and often also use different terminology. Therefore, before going into migration from WildFly to Payara Server, we’ll provide you with an overview of similar features and concepts that exist in both WildFly and Payara Server.

With the lock downs raging on, more events are being cancelled and postponed. The upside is many have also pivoted to being virtual and many advocates are now pumping out interesting webinars and videos. The quality of content has also certainly not diminished, so read on dear reader!

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! 

We wanted to let you know that we've decided to self-host our documentation due to the shutdown of legacy Gitbook. There are a few minor changes you'll want to know regarding how you access and read the Payara Platform Documentation.

After you've got familiar with administering Payara Server, having configured your domain and deployed your applications, you might find it useful to get some more information on features supporting maintenance of your domain in the longer term.  If you are not quite there yet, have a look at our resources page or our getting started page.

All companies are software companies, and businesses will always experience the challenge of keeping integrations between users and applications scalable, productive, fast, and of high quality. To combat this, cloud, microservices, and other modern solutions come up more and more in architectural decisions. Here is the question: Is Java prepared to deal with these diverse concepts in a corporate environment?

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. This article will explain more about introducing Docker. 

Using Payara Server for the first time?

We’ve put together this step-by-step “Getting Started Guide” to help you with everything you need to successfully install and put Payara Server to work for you, including:

Watch this video to learn how to create a secure web application using multiple Java EE/Jakarta EE APIs and connect it to a MySQL 8 database in this comprehensive tutorial.

MicroProfile Health is an API designed specifically for use in cloud and containerized environments, where you want to quickly determine if an instance of an application is unhealthy and restart it. How exactly do you use it though? In this session, I’ll run through how to add some health checks to your application, and how to configure a number of cloud providers and containers to effectively use them to restart your application instances.

In this tutorial, I will explain how to add the Payara Server in the Visual Studio Code and deploy the maven web application to the Payara Server.

I was very determined this month to try and get this blog out on time! A lot has happened this month! Java 14 was released. Some virus thingy means everyone is working from home. Conferences and events are almost all cancelled all delayed, globally. Some have transitioned to virtual events.

In this day and age, securing enterprise platforms is a challenge that developers and consultants tackle in an uninformed manner, producing subpar solutions in most cases. To combat this pattern, third-party security services such as Auth0 have been devised to externalize the security of services, and they focus on stable implementations of common enterprise use cases (identity management, OAuth compatibility, and so on), and platforms such as Eclipse MicroProfile allow for their easy integration with enterprise Java microservices. Moreover, in combination with Kubernetes, MicroProfile is a very powerful tool to simplify securing microservices, monitoring them and creating reproducible deployments.

We've published a number of blogs about the updates and new features with the Payara Platform 5.201 release, but here are the highlights in case you've missed it:

Being productive gives developers a sense of satisfaction and fulfillment. That's why increasing developer productivity is always our priority and we are consistently working towards improving the Payara Platform developer tools and the developer experience.

In this blog, we will show you how to configure a Project in the Apache NetBeans IDE to enable Auto Deploy and Hot Deploy mode.

The Auto Deploy and Hot Deploy mode are helpful for developers to run and test an application immediately after making changes to its sources without restarting the Server or manual redeployment to maximize your productivity where Auto Deploy is the feature of Apache NetBeans IDE and Hot Deploy is the feature of Payara Server. Hot Deploy mode is currently only supported in Apache NetBeans IDE as an experimental feature.

Transport Layer Security (TLS) was introduced as a replacement for Secure Sockets Layer (SSL). TLS is a cryptographic protocol which provides secure communication between a client and a server. It also provides a mechanism by which information is not tampered with, falsified or read by anyone other than the intended receiver. TLS 1.3 was released in August 2018 to replace the widely used TLS 1.2. TLS 1.3 comes with stronger cryptographic algorithms and brings in major improvements in performance, security and privacy, which will be discussed in this blog.

Starting with the latest Payara Platform 201 release, we've made changes to how we build and report our future platform roadmap. We recently introduced the Payara Reef initiative to enhance our communication with the Payara community, and as part of the Reef initiative, we are also introducing the Open Roadmap for the Payara Platform.

It's been a little while since the last update. Your humble author has been on the road, most recently DevNexus in Atlanta where we met many awesome people and had a great time. We also just published our latest release Payara Platform 5.201.  We wont lament further, as usual we have kept our eyes open and have been squirrelling away some great content.

I talked in JakartaOne Livestream Japan held at 26th of February 2020 as behalf of Payara Services Team!

このイベントは、昨年9月に開催されたJakartaOne Livestreamに感銘を受けた日本のJavaコミュニティ有志が企画したバーチャル・カンファレンスです。私もこのカンファレンスのプログラム委員の一員として、カンファレンスの事前準備や当日の運営に携わりました。このようなイベントは日本ではまだ例がなく私たちも（当日のカンファレンス進行中でさえ）試行錯誤しましたが、日本のJavaコミュニティに広くJakarta EEとMicroProfileをご紹介しようと最善を尽くしました。

Payara Micro 5.201 adds two command line options that make preparation of container images easier, as well as enable class data sharing on HotSpot Java Virtual Machine.

The first Payara Platform release in 2020 is out. Highlighted updates include new End-to-End data encryption and the extension of the Monitoring Console. The release includes 31 bug fixes, 5 new features, 12 improvements and 21 component upgrades!

Check out the release notes here.

How do you feel about being a Java Champion?

I have to admit I was genuinely surprised because I didn't see it coming. I knew there was no Java champion in Czech Republic, but I never thought that I would become the first one. It's an honour for me. Especially because I'd already met many Java champions and became very good friends with some of them. And now I'm part of the gang of all those people that are making so much for the Java community.

The first release of the Payara Platform in 2020 syncs the Stability and Community streams.  For those not in the know, the Community stream is what we call our quarterly public releases, and the Stability stream is what we call our monthly bug fix-only releases for those with the supported version of Payara Platform Enterprise, (see here for more info on the release streams).

Encryption of the data stored within the data grid of Hazelcast (the technology underpinning our deployment groups and clustering in Payara Platform 5) has until now required a Hazelcast Enterprise subscription (see Payara Scales). While this remains an option for those who would like the additional features it provides (such as WAN replication), we’ve begun introducing this particular feature into Payara Server itself to provide it to you without needing an additional subscription.

This is Part 2 of our Payara Server - Back to Basics series, see Part 1 - Installing Payara Server on Ubuntu here.

In order for a web application to run, it must be first deployed on an application server such as Payara Server. Deployment in the context of web applications is the act of installing the application on a server. It allows requests to be handled and so on. This guide will provide you with a few different ways to get your application running.

In Payara Platform 5.194 we introduced the monitoring console. The upcoming 5.201 release now offers numerous improvements and additions. We continued to followed our vision of a monitoring tool that users can configure to their needs, ranging from new tools such as watches and alerts, to new colour themes and settings users can tweak to match their individual preferences.

Dockerとは? DockerとPayara Server/Payara Microを一緒に使うには?

The transition of Java EE to the Eclipse Foundation is now complete with the release of the Jakarta EE 8 Platform Specification and the compatible implementations, including Payara Server. The release plan for Jakarta EE 9 is also approved, and will move all the Java EE APIs to the jakarta namespace - providing a future platform for Jakarta EE 10 and beyond.

One of the performance metrics that are frequently compared  by developers are startup times. Payara Server is designed to be manageable at runtime, with a central management server (DAS - domain administration server) and multiple instances, and as such is not optimized for extremely fast startup time. Payara Micro on the other hand, is optimized to run predefined workloads with a stable configuration at runtime, and is therefore a better fit for for comparing start up time metrics.

In this blog, let's take a look at how you can configure Payara Micro for fast startup time by utilizing the class data sharing feature of Eclipse OpenJ9.

With Spring Boot you can create an executable JAR file or a WAR file that can be run on a server. The latter option can also be used with Payara Micro. This blog shows you the different steps in creating and running such an application.

The approval of the Jakarta EE 9 Release Plan is a great milestone for the Jakarta EE project and a stepping stone towards the evolution of Jakarta EE into a project that meets the community's needs and wants. View the approved Jakarta EE 9 Release Plan here.

This is Part 1 of our 'Payara Server- Back to Basics' series, where we will show you a step-by-step overview of how to install Payara Server 5 on Ubuntu. 

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.

嬉しいお知らせです。Payara Platform 5.194から、Payara Serverにはサーバーの状態を可視化できる組み込みの監視コンソールが搭載されます。

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.

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!

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 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 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.

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! 

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.

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.

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.

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.
