Why Jakarta EE is Better than the Competition

Jakarta EE is the most popular Java server-side framework, way ahead its alleged competitors such as Spring, Quarkus, Micronaut or Dropwizard. With the industry-wide adoption of microservices based architectures, its popularity is skyrocketing and, during these last years, it has become the preferred framework for professional software enterprise applications and services development in Java.

In this blog, I'll explain more about Jakarta EE from my perspective as a Senior Java software architect/developer and why Jakarta EE and its runtimes beat the competition, in my opinion!

Using Jakarta EE Identity Store With Payara

These days the world-wide open-source community celebrates the advent of Jakarta EE 10. It is then a good time to look at one of its most relevant and, at the same time, unknown parts: security!

In this blog, I'll give an introduction to Jakarta EE Security, and then explain how Payara Platform builds on Jakarta EE Security with built-in identity stores for RDBMS (Relational Database Management System) and LDAP (Lightweight Directory Access Protocol).

What's New in Jakarta EE 10?

Jakarta EE 10 will be released on September 22! It's almost here...

While the previous releases of Jakarta EE have been focussed on the much-feared namespace change and updating everything with support for Java 11, this is the first major release of Jakarta EE to start introducing new features for developers to use. I’ll cover some of them here.

Deploying to Payara Cloud from a GitHub Action Workflow

Payara Cloud provides an easy-to-use user interface to allow your application to run in a managed cloud environment. While this is very convenient for configuration and troubleshooting work, integration in continuous deployment pipelines calls for something else.

 Our answer is deploying to Payara Cloud using a GitHub Action Workflow and Payara Cloud Command Line (PCL). 

The Payara Monthly Catch: August 2022

August is typically a quiet month, and whilst this is the case in terms of industry announcements, there have been incredible learning resources and general Java articles created. Here, we have rounded up some of the best of them, covering DevOps, cloud computing, Java, Jakarta EE, MicroProfile and open source.

August Payara Enterprise Release

Payara Platform Enterprise 5.42.0 brings 5 bug fixes, 1 improvement, 1 component upgrade and 1 key security fix - of a 0-day vulnerability in all distributions of the Payara Platform that affects web applications that are deployed in the default context root(/).  

A release of Payara 6 Community (Alpha 4) and Payara Community Version 5.2022.3 will follow next week. This will bring the fix to Community users, providing they update to these versions.

Payara Enterprise = A More Bespoke Solution

Payara Enterprise is an alternative to WildFly, JBoss EAP, WebSphere and more. 

With Payara Enterprise, you have everything offered by Payara Community - regular releases, a global community of 80,000 active users, cutting edge Jakarta EE technology - with the added benefits of support from our engineers, special features like a tool for upgrading and a 10-year software lifecycle. 

Ignore Infrastructure and Concentrate on Code with Jakarta EE and Payara Cloud

Java EE, now Jakarta EE, makes it possible for developers to focus purely on the development of a Java enterprise application, solving the business logic without needing to think about infrastructure and operations when writing code. Payara Cloud extends this philosophy by also eliminating the need to worry about infrastructure and operations when preparing your application to run in the cloud. Together, Jakarta EE and Payara Cloud let you focus on writing code and delivering solutions to business challenges from the moment you write your first piece of code to the day people are using your application successfully on the cloud.

We are currently offering limited free previews of Payara Cloud to businesses - follow the link below:


What is MicroProfile?

Java programming language can be enhanced with specifications. An specification is a baseline platform definition - a framework - to guide concrete implementations. 

One of these specifications is called MicroProfile. But what is MicroProfile specification, what is it used for and why might you need it? 

This blog explains all. 

What's New in the July 2022 Payara Platform Release?

The Enterprise-only 2022 July Payara Platform release is here!

Payara Platform Enterprise 5.41.0 brings 2 bug fixes, 2 component upgrades, and 2 improvements.

This month, this includes improving the functionality of the Upgrade Tool, which is available to Payara Enterprise customers only. Also only for Enterprise users is Azul's supported OpenJDK build for enterprises, Azul Platform Core. In this release, we've updated our Docker images to support new versions of Azul Platform Core. We've also updated our Docker images of previous releases with these new versions of Azul Platform Core.

An Enterprise subscription means you can access special benefits like the Upgrade Tool and bundled Azul Platform Core support, as well as being able to continue using earlier Jakarta EE versions after Jakarta EE 10 is released this month (see below).  All these benefits mean an Enterprise subscription can be more cost-effective in the long-run! 

What is a Java Uber-JAR and Why Is It Useful?

An uber-JAR, also known as a fat JAR or JAR with dependencies, is a JAR file that contains not only a Java program but embeds its dependencies as well, and might also contain the web application that needs to be executed.

In this blog, we'll describe the different variants of the artifact, and the advantages and drawbacks it has.

What's New in the June 2022 Payara Platform Release?

The June 2022 Payara Platform release is here! This is an Enterprise-only release, with Payara Platform Enterprise 5.40.0 bringing 3 bug fixes, 1 component upgrade, and 2 improvements.

 We have also made significant improvements to our product documentation on GitHub, for both Enterprise and Community, aiming to create the best developer experience possible for those using the Payara Platform! Read more below.

Use Hibernate as a JPA Provider within Payara

The Payara Platform promises aggressive compatibility. Because we focus on providing an excellent application server, we do not seek to lock you in to a product suite or any particular tools. As you see in this blog, this is also true in the case of which implementation of the Jakarta Persistence API specification you choose to use. We explain why we run automatically with EclipseLink, but also why and how you may switch to Hibernate. 

Choose the tool that is right for your specific use case. 

The Payara Monthly Catch: May 2022

We provide our selection of the best Java and Jakarta EE tutorials, videos, podcasts, blogs and news from the month of May! We also pick the best content we've found from the worlds of DevOps, cloud computing and open source. This is a carefully curated reading list, specially selected for our specific Enterprise Java niche. 

What's New in the May 2022 Payara Platform Release?

The May 2022 Payara Platform release is here! This is an Enterprise-only release, with 5.39.0 bringing 4 bug fixes, 2 component upgrades, and 5 improvements. 

JDK 17 is now supported in Enterprise! It has been tested in Community and can be relied on for mission-critical systems. Enterprise users also enjoy an improved Upgrade Tool, with more troubleshooting available when moving between Payara versions.

The Payara Monthly Catch: April 2022

Every month, we collate the very best content for our specific enterprise Java - Java EE, Jakarta EE and MicroProfile - community. We also look further afield, and where it applies, include interesting blogs, videos and articles on subjects such as DevOps, cloud computing, microservices, software architecture and more. 

TL;DR: We know our audience and if we think you will find something very useful when developing enterprise Java applications - it makes the cut! 

How Does Payara 6 Affect Your Application’s Future?

The release of Payara 6 Community in a few weeks will be a turning point for many of our users. It's important you review all possibilities in advance. Consider migration to be supported, secure and maintain peace of mind!   

We recommend moving to Payara Enterprise,  which we consider the most cost-effective and business-savvy choice. In this blog we explain 5 different scenarios.

Google Remote Procedure Call (gRPC) Example in Payara Server

Google Remote Procedure Call, or gRPC, is an open source Remote Procedure Call (RPC) framework focused on high performance and portable to any environment. It is an alternative to REST, deemed by many as more efficient.

After one of our customers requested it, the extension became available in our April 2022 Payara Community and Enterprise releases: 5.2022.2 and 5.38.0. 

What's New in the April 2022 Payara Platform Release?

The April 2022 Payara Platform release is here! Payara Platform Community 5.2022.2 brings 13 bug fixes, 2 component upgrades, 3 improvements and 3 security fixes, whilst Payara Platform Enterprise 5.38.0 includes 2 bug fixes, 1 improvement and 4 security fixes. 

It includes the fix for "Spring4Shell", and improved support for Jakarta EE 9, as you can now run Jakarta EE 9 applications using PrimeFaces.

This release also gives Payara users the ability to use gRPC, the Google Remote Procedure Call Framework.

Please note: This is the penultimate Payara 5 Community release. Payara 6 Community will soon take its place, to be used with Jakarta EE 10. If you want to keep using earlier Java EE/Jakarta EE versions - we encourage you to move to Payara 5 Enterprise.

Easy Jakarta EE Integration Testing with the Payara Platform and Testcontainers

One major issue when developing modern enterprise applications is the "works on my machine" problem: when an application works well on your machine but is not functional in production or even on a colleague's machine. An even more prevalent problem is to maintain the quality of ever-changing applications during development and maintenance. 

This is especially prevalent when Jakarta EE applications are developed and not properly tested in an isolated and cohesive manner. Proper integration testing helps to avoid both the "works on my machine" problem, and ensures developers can change the application effectively without breaking it. However often teams struggle with it, due to a lack of standardized testing solutions and the unpredictability of real-world conditions. 

Here, I present an effective method for Jakarta EE integration testing, using Payara Platform and Testcontainers in my example.

What is Jakarta EE?

Java is the world’s third most used programming language, and the basis of some of the world’s biggest software projects.

If you are running a large, enterprise application - supporting commercial projects - Java alone may not be enough. You need to use it with Jakarta EE, formerly called Java EE.

What's New in the February 2022 Payara Platform Release?

The February 2022 Payara Platform release is here!  Payara Platform Community 5.2022.1 includes 3 improvements and 10 bug fixes. Payara Platform Enterprise 5.36 brings 3 improvements and 4 bug fixes. 

We also released a second alpha version of Payara 6, with the headline news being that it now includes support for MicroProfile 5.0!

Read more below to learn about the highlights.

New Guide: Migrating WebSphere Application Server to Payara

We recently created a new guide to help you move from WebSphere Application Server to Payara Server 5.

Payara is better than WebSphere, for reasons including Payara's more regular releases, greater variety of supported IDEs, a compatible microservices edition (Payara Micro) and varied monitoring options.

Hermes, the logistics provider, is just one company which made the change from WebSphere to Payara Server! 

Payara Platform in 2022!

As 2022 moves into its second month, we provide a short and sweet update on what you can expect from the Payara product suite this year.

You can watch the full interactive question and answer session with our Founder and CEO Steve Millidge below, or catch up in this quick summary. 

New eBook: Dismiss the Java Myths!

Our new bumper eBook tells you all you need to know about Jakarta EE and busts common misconceptions. 

Spoiler: Jakarta EE is NOT heavy; it IS cloud-native; it easily delivers microservices. The Jakarta EE (previously Java EE) standards offer a choice of runtime, vendor neutrality and longevity - what are you waiting for?

Should you use OpenShift to Run Payara in the Cloud?

The world is moving to containerized workflows. As a result, tools to handle containerization become more and more important.

Kubernetes is the most widely used platform for managing and orchestrating containers. But since it contains only the basic building blocks, you need additional tools if you want to set up your environment for running applications on it.

In this blog, we take a closer look at Red Hat OpenShift and the comparison with Kubernetes.

When Is It Time To Move From Payara Community to Payara Enterprise?

Which version is right for me?” … we get asked this question all the time, so we wanted to provide you with a more in-depth discussion that outlines similarities and differences to help explain why you would want to choose one or the other.  

We thought it might be helpful to enumerate some of the differences between two editions: 

Payara at the JakartaOne Livestream

The JakartaOne Livestream is a huge event in the Jakarta EE and MicroProfile calendar. Organised by the Eclipse Foundation, it is a one-day virtual conference for developers and technical business leaders.

It brings insight into the current state and future of Jakarta EE and related technologies focused on developing cloud-native Java applications. 

Comprehensive Getting Started Guide – Payara Server

Payara Platform is an open source middleware platform that supports Jakarta EE (formerly Java EE) applications in ANY environment: on premise, in the cloud, or hybrid. 

It is a solution to GlassFish problems such as lack of supported Docker images and automation assistance, no internal monitoring system and an absence of modern security standards and critical server event alerts and notfiers. It is also an alternative to Oracle Weblogic, Wildfly, JBoss EAP, WebSphere, OpenLiberty and more. 

Our previous Getting Started guide had not been updated with improvements to Payara Platform, such as our hide password with password aliases feature - and did not contain comprehensive guides to integration with other technologies.

Hype-Driven Development: Don't Be a Victim!

We are launching a new video series: Quick Fire Java with Payara! The first episode sees Payara Product Manager, Rudy De Busscher, discuss "Hype-Driven Development"; software investments based on "buzz" around a trend or product, rather than whether it actually works for your specific use case. 

What's New in the December 2021 Payara Platform Release?

The December 2021 Payara Platform release is here!  Payara Platform Enterprise 5.34.0 includes 7 improvements, 1 security fix, 8 bug fixes, and 1 component upgrade. The Payara Platform Community 5.2021.10 release offers 6 improvements, 1 security fix, 7 bug fixes, and 2 component upgrades. 

You can download Payara Platform Community 5.2021.10 here and request Payara Platform Enterprise 5.34.0 here.

Payara Platform November Roadmap Webinar

In regular webinars, our CEO and Founder Steve Millidge provides an update on the progress of Payara Platform: what we've achieved in relation to our yearly roadmaps, and what we have left to do! 

In this webinar, Steve looked at what we've achieved so far in 2021, and ahead to the final quarter of this year and plans for early 2022.

Getting Started with Jakarta EE 9: Jakarta Validation

In this last blog of the Getting Started with Jakarta EE 9 blog and video series, we have a look at the Bean Validation specification. Using this specification, you can define some validation rules, from some simple ones on a single field to very complex ones on a business entity, that are reusable depending on the input frameworks you are using within your application.

JDK17 Support in Payara Community

JDK 17 is the latest Long Term Supported (LTS) version of the Java platform, released in September 2021. LTS versions will have regular releases for the coming years and you don't need to switch to a newer version after 6 months as you do with those 'interim' JDK versions.

The features in an LTS version are kept stable so it is ideal for running  your enterprise applications. Once you switch to an LTS, you can safely update to any minor release to accommodate for security issues and bug fixes of the JDK platform, but without needing to perform a migration.

With the release of the November 2021 version of the Payara Platform Community Edition, Payara Server, Payara Micro, and the Web Profile run on JDK 17 platform.

Payara Platform October 2021 Survey Results

We’re pleased to announce that our October 2021 Payara Platform Survey results are now available! 

This survey was promoted to our audience in October 2021. We shared with Payara Platform Enterprise customers and Community users via social media, emails and blogs. Thank you so much to everyone who took the time to contribute!

Running Payara Server as a Service - Added Support for systemD on Linux

Before your application can respond to any request from the user, Payara Server needs to be started as a process on a machine. The Payara Server Domain instance or a Payara instance can be started using the Asadmin CLI tool.

But in many cases when you run Payara Server on an on-premise machine or in a virtual machine, you want to start the Payara process automatically when the machine is booted. You can do this by defining Payara as a Service on the machine.

VIDEO: Adam Bien - The Future is Now (Payara Cloud)

Adam Bien explored the possibilities of Payara Cloud in his recent talk for the 2021 J4K conference! 

He used the Payara Cloud demonstration environment - with the caveat that the user interface is not completed yet - to demonstrate how our next generation application server creates a "serverless" environment; moving the "plumbing behind the scenes" so you only have to worry about selecting your WAR, clicking deploy, and running it on the cloud! 

VIDEO: 7 Reasons to Switch to OpenJDK 17 as a Jakarta EE Developer

JDK 17, the next Long-Term Release of Java SE, launched in September. You may have seen many of the great blogs, articles, and videos about what this means for Java developers. For just a few places to start, we like: theJetBrainsteam'sdiscussion on migrating to JDK 17; Todd Ginsberg onhis ten favourite features; andGunter Rotsaert mapping out thedifferences between Java 11 and Java 17. 

But what does the new release mean forJakarta EEdevelopers specifically? If you are using these enterprise-orientated specifications, stewarded by theEclipse Foundation, should you make the switch?

Payara's Rudy De Busscherthinks you should, and explained why in his talk toIstanbul JUG, powered byHazelcast.

The Payara Monthly Catch: October 2021

In October, ourJavaandJakarta EEcommunity has still been digesting the new long-term support release, JDK 17, out last month. Below, find useful articles such as theJava Champions demystifying the new licensing,Per Liden on the inclusion of Z Garbage Collection, andGunter Rotsaert on differences between Java 11 and Java 17- some of our favourite experts are helping the community get to grips with improvements and changes!  

The innovative Payara team are always looking forward though, and work is in full swing for Jakarta EE 10. Particularly popular this month was a blog by our CEO Steve Millidge, who is project lead for the Jakarta Concurrency project, a specification within theEclipse FoundationJakarta EE that works on transferability between Java SE Concurrency and its enterprise-orientated counterpart. Make sure you check it out if you are interested in honing your open source skillls by contributing to a project (Steve is actively looking for volunteers to test, write documentation and develop) but also if you want to know more about what you can do with Jakarta Concurrency in its current form.

Big news also is the new and improvedPayara Forum. We've moved from Google Groups to a new location that makes it easier to discuss use of Payara Platform with like-minded developers - and our engineers! Make sure you have investigated it. 

In addition to JDK 17 tips and tricks, and Jakarta Concurrency content, please find below our pick of the best blogs, articles, videos and podcasts from the world of Java, Jakarta EE, MicroProfile, open source and DevOps over the last month. We also include industry news and where you can find Payarans across the web!

Client Certificate Realm Configuration in Payara Server

A realm is the security policy domain within an application server. It defines how the authentication and authorization for your application is performed. Most of the time, your application is used by a person that can provide username and passwords as credentials (directly or indirectly through providers like an OpenId Connect provider) but some use cases exist where another process needs to use your endpoints.

Jakarta Concurrency: Present and Future

Jakarta EE, previously Java EE, is a set of specifications that enables the world wide community of Java developers to work on cloud native Java enterprise applications. It is an open source project maintained by theEclipse Foundation.

Jakarta Concurrency is a small, but fundamental, specification under the Jakarta EE umbrella. As project lead, I provide more information on what it is, its future and how to be involved.

Configure the Details of the GZIP Compression in Payara Platform October 2021 Release

Data is sent to and received from the endpoints within Payara Platform. When large chunks of data are sent to the client in response to a request, it might be an option to compress the data when the bandwidth is limited.  This speeds up the transfer, but requires more CPU on the server and the client to perform the compression and handle the response.

With the October 2021 release, the Payara Platform allows configuring the compression level and the compression algorithm so you can better tune your environment for your requirements.

Client Certificate Validation in Payara Platform October 2021 Release

The Client Certificates security extensions continue to receive improvements in this release. In previous releases (July and September 2021) we added Client Certificate Authentication improvements, giving the ability to define multiple TrustStores and implement a SPI to allow developers to perform additional checks on the Client Certificate.

Previously, any Client Certificate that is used and matched within the KeyStore was accepted, even when the certificate was expired. Starting in the October 2021 releases (Payara Community 5.2021.8 and Payara Enterprise 5.32.0), using the newly developed SPI, we have implemented an additional check when using the Client Certificate authentication option to ensure the certificate is valid.

What's New in the October 2021 Payara Platform Release?

The October 2021 Payara Platform release is here!  Payara Platform Enterprise 5.32.0 includes 8 improvements, 9 bug fixes, 1 security fix, and 5 component upgrades. The Payara Platform Community 5.2021.8 release offers 7 improvements, 7 bug fixes, 1 security fix, and 5 component upgrades. 

You can download Payara Platform Community 5.2021.8here and request Payara Platform Enterprise 5.32.0 here.

Official Microsoft Azure Sample for Payara Micro

Payara Server has a strong relationship withMicrosoft Azureand theJava at Microsoft team - and now, there's an official best practice Azure Sample for running Payara MicroonAzure Kubernetes Service(AKS)! 

This is a reaction to more and more Azure customers wanting to run Payara on Azure, with many moving from GlassFishto Payara Micro on AKS. It also precedes the next step for Azure and Payara:  releasingPayara Cloud as a PaaS running on Azure.

How to Search Log Entries in Payara Cloud

Payara Cloud (launching soon!) delivers an easier way to run your Jakarta EE applications on the cloud. You can upload any web application that follows the Jakarta Web profile specification and click deploy - Payara Cloud will configure and run it in a containerized Payara Micro instance.

Unlike building an application server deployment on a Cloud Infrastructure as a Service or on raw Kubernetes, Payara Cloud takes on a Platform as a Service (PaaS) role and handles provisioning of the infrastructure, installation, configuration, deployment, and scaling your application to eliminate costs and reduce the risks of managing Jakarta EE application servers on Cloud.

You can search the log entries easily within Payara Cloud if you suspect errors or expect a message within the log file. 

The Payara Monthly Catch: September 2021

We hope you enjoy our September Payara Monthly Catch - a collection of articles, videos & podcasts around Java, Jakarta EE, MicroProfile, open source and cloud computing! 

This month the major news for the Enteprise Java community community was the release ofJDK 17, the next Long-Term Support (LTS) OpenJDK release. Find our pick of the best resources relating to this below, including Payaran Rudy De Busscherexplaining how Payara Platform will soon support JDK 17 and why. 

TheEclipse FoundationJakarta EE Developer Surveyresults also came out, revealing that Java EE 8, Jakarta EE 8 and Jakarta EE 9 are now hitting the mainstream, with 75% adoption among respondents. 

It's also been a great month for resources and compatabilities for our related technologies: Jelastic has introduced an auto-clustering option for use with Payara, andAzure produced an official best practice sample.  More related technologies are realising how many of their users want to use Payara Platform, and creating tools to make this easier! 

Using Hazelcast SQL with Payara Micro

Co Authored with Nicolas Frankel (Hazelcast Developer Advocate), this article is also available as a PDF.

The Hazelcast In-Memory Data Grid (IMDG) is an efficient method of storing data in a distributed way within the memory of the different processes of the cluster. Because it is distributed, searching the data locally requires 'moving' the data to your instance so it can be accessed, which is not overly efficient.  Hazelcast SQL allows distributed queries which perform the search where the data is, and then transfers only the results to your process. Since the Payara products already use Hazelcast IMDG, using the Hazelcast SQL capabilities is straightforward: just add the additional JAR library to start using it.

Getting Started with Jakarta EE 9: Jakarta Faces (JSF)

With Jakarta Faces, you can build user interfaces for web applications, including UI components, state management, event handing, input validation, page navigation, and support for internationalization and accessibility. It is a server-side framework that allows for rapid development of web applications, mainly administrative applications which are data entry and business logic heavy. The web pages are created by defining the components that are required and the events that are triggered by the user, and the rendering happens in a separate phase that can be customised to your needs.

In this blog, we mention a few features of Jakarta Faces 3.0 as it is one of the largest specifications of Jakarta EE 9.

Getting Started with Jakarta EE 9: Jakarta Persistence API (JPA)

With the Jakarta Persistence API, the system can perform the serialization of Java Objects into the Database or read data into objects. You can use Jakarta JPA to read and write Java instances easily from and to the database.

With the help of annotations on Java classes and instance variables, the mapping is defined between the Java world and the database world. 

In this blog, we cover some of the basic aspects of the JPA specification and how you can use it.  The specification is rather large so make sure you also consult some documentation and other resources to find out all the capabilities of the specification.

Client Certificate Authentication Improvements in Payara Server July and September 2021 Releases

SSL certificates are used for several features within Payara Server. You can configure your custom certificate for the TLS based connections the Payara Server is serving when using a custom domain name. And those certificates can be used for authentication purposes to identify the caller, mainly in a machine to machine communication.

With the July and September 2021 Payara Server releases, we have implemented two new features to improve the usage of these custom SSL certificates.

What's New in the September 2021 Payara Platform Release?

The September 2021 Payara Platform release is here!  Both Payara Platform Enterprise and Payara Platform Community Editions include a security fix that requires you to take action to ensure the security of your environment. (Explained below).

Read All About It: Interviews With Our CEO Steve Millidge

Did you know? Payara Services is the proud recipient of a 2021 Queen's Award for Enterprise - International Trade. Often called the "Knighthood for Business", theQueen's Award is the UK's premier business accolade. 

On the back of this achievement, our CEO and Founder Steve Millidge was in high demand as an interviewee. In two recent interviews, you can find out more about what winning this award meant, Payara as a business, more about our open source business model and even Steve's motto! 

Real-World Use Case: Robust and Flexible Batch Processing with Payara Platform

One of the Payara Platform features people like most is flexibility for how it can run applications and services and connect them to each other. You can run applications on Payara Server, Payara Micro, and cluster them all together in the same Domain Data Grid, while using the same technology for building the applications and the samefeatures in both Payara Platform runtimes. A lot of our customers take advantage of this flexibility and some even take to the extreme, as described below.

Is the Java EE Deployment Model Out of Date? Watch The Video.

We are now sharing the FINAL video in our'Dismiss the Myths: Get to Know Jakarta EE (Java EE)'. 

This one asks the question: 'Is the Java EE Deployment Model Out of Date?'. We definitely don't think so! 

Steve Millidgeshows you why the Java EE (Jakarta EE) deployment model is not old fashioned or out of date - and goes into battle with Spring!

How and When to Disable Domain Data Grid in Payara Server

Payara Server comes with the Domain Data Grid, a very powerful feature related to the clustering capabilities of the product. If you're deploying the application on the domain server itself and are not using any clustering options, it's possible to disable the Domain Data Grid to slightly reduce Payara Server's start up time - but should you?

The Domain Data Grid can be disabled but be aware that a few other features in Payara Server also depend on the Domain Data Grid.

How to Set Custom Domains for your Applications in Payara Cloud

Payara Cloud is an all-in-one serverless platform and PaaS solution for Jakarta EE (Java EE) and MicroProfile applications that simplifies cloud infrastructure management. With Payara Cloud, you don’t need to worry about application servers or deal with Kubernetes. Standard and Premium Payara Cloud subscribers can set custom domains for their applications.

Monitoring JMX Using the Notification Service

Within Payara Server, the JMX system is used to store all the data that the monitoring service captures of the modules within the runtime.

You can use any tool that can connect to the JMX system to collect these data and monitor the environment. Besides this direct access, the notifier service can send this information to various channels so that the data can be integrated with external systems.  

The Notifier service is modular since October 2020 with version 5.2020.5 so that you can include only those notifiers that you are interested in and use within your environment. These notifiers cover a wide range of channels, from typical destinations like email, JMS Queues, over APM tools like DataDog and NewRelic to communication platforms like Teams, Slack, and Discord.

In this blog, we take a look at enabling JMX Monitoring for the JVM Heap Size, monitoring the process Heap Size, and then sending that information to a Discord channel.

Steve Millidge discusses Jakarta EE, the Eclipse Foundation & GlassFish's future on the WaterWorks Podcast

Our CEO and FounderSteve Millidge is a guest on the WaterWorks podcast, the technology discussion podcast run by journalist and authorJohn K. Waters

Waters is the editor in chief of theConverge360 news and information sites Application Development Trends(ADT Mag), Pure AI, and Futuretech360 - with his career also including writing books, including "The Everything Guide to Social Media," one of the first deep dives into this world-changing phenomenon, and "Blobitecture," an exploration of an architectural and industrial design trend enabled by computer software. He also co-scripted the documentary film "Silicon Valley: A 100 Year Renaissance," which aired on PBS.

Steve had a conversation over Zoom with John. Steve - in Malvern, England, after work - spoke to John - in his Silicon Valley office just before 9am. Their discussion was wide-ranging and insightful, covering everything from the future of Jakarta EE and how it will fare under Eclipse Foundation stewardship, to the specifics of Payara's journey and how we got our marine logo! It's a must listen for those interested in open source and Enterprise Java. 

Why Use Alibaba Cloud with Payara Platform?

We are all familiar with Microsoft Azure, Google's GCP, or Amazon's AWS platform for running applications in a public cloud. But there are also other, lesser-known platforms like Alibaba Cloud.  And while many don't know this platform, it is by far the largest one in the Asia Pacific region and even the third largest cloud provider worldwide. Alibaba Cloud has some interesting features.

In this blog, we explore some aspects of the platform and how it can be used with the Payara Platform.

Adam Bien: Overview of Next Generation Cloud Java Runtimes (Video)

As part of Closed Beta testing, we offeredJakarta EEexpert, Java Champion,bloggerand podcaster,Adam Biena trial of our next-generation cloud-native application runtime,  Payara Cloud. 

He went on to discuss Payara Cloud as an alternative to HelidonandQuarkus; a 'serverless server'. He included it in hisMid-Year 2021 Observations and Reflectionsand created a video with hisinitial thoughts. Read our previous blog, rounding up his comments so far,here.

At theJ4Kconference this year, he went into further detail. He told viewers:“I really like the idea [of Payara Cloud]. Why? Because it is the opposite of where everyone is going with smaller and smaller runtimes, you can go that route or another route.” You can now view the video of this talk to watch him demonstrate Payara Cloud live and see how he reached this conclusion.  

Are Java EE Application Servers Heavy? Watch The Video.

Our summer webinar series continued with 'Are Java EE Application Servers Heavy?'

In thismyth-busting webinar, Steve Millidge (founder of Payara), showed viewers that Java EE application servers are NOT resource-heavy or slow.  His live demonstrations showed it’s possible to have a small footprint and low resource usage in Jakarta EE runtimes.

If you missed the webinar earlier this month, you can now watch the video!

The Payara Monthly Catch: June 2021

June has been another busy month here at Payara Services, both internally - with our biggest yearly company event, Payara Week, taking place - and externally - with our 'Dismiss the Myths' Webinar series kicking off and proving to be one of our most popular community events yet. 

We're halfway through 'Dismiss the Myths: Get to Know Jakarta EE (Java EE)' , a series of 6 webinars where our CEO and Founder Steve Millidgedismantles common misconceptions one by one. Check out thisblog for links to watch webinars that have already taken place, and sign up to the next three! 

As for Payara Week, you may have seen the social media content around our team-building, future-planning, fun-having annual company summit - this time virtual, but no less engaging! We'll be following up with a full blog with pictures and details, but peek at one of the reimagined Payara Fishes from the week's photo competitions below. 

We also got a Twitter blue-tick this month - proving once and for all that we are 'authentic, notable and active' - in our case, when it comes to providing top Jakarta EE and Java EE, MicroProfileand cloud content!

Momentum also continued to grow for our next-generation cloud native application runtimePayara Cloud, with key influencer Adam Bien presenting on it as an alternative toHelidon and Quarkus at the j4k conference. You can find out what he already had to say in his initial trial of the product here. 

But it hasn't all been 'the Payara Show'. We've also searched for and shared the best tutorials, updates, news, articles and videos from our wider community - find them below! 

Is Java EE Outdated and Dead? Watch The Video.

We are almost halfway through our summer webinar series! Across 6 online events, our CEO and FounderSteve Millidgeis discussing common misconceptions aroundJava. He's broken down false views of the programming language, and its enterprise-orientated iteration Jakarta EE, into 6 topics - tackling them one by one and showing that Java is still relevant. 

Each session is concise - around 30 minutes - and you don't need any previous knowledge of Java or Jakarta EE. 

Watch Adam Bien Trial Payara Cloud! (Video)

Adam Bien is a well-known expert in the world ofJakarta EE. He is a freelancer, author, Java Champion andblogger, providing resources and training materials, and is host of theAirHacks.FM podcast - where he regularly talks to the leading experts in the Java and Jakarta EE community, with recent guests including PayaransLenny PrimakandRudy De Busscher

As a long time user of the Payara Platform - regularlyrecommending it as a solution to GlassFish problems - we were keen to offer him a trial ofPayara Cloud, our next generation of cloud-native application runtime. Payara Cloud offers an easier way to run Jakarta EE apps on the cloud, allowing you to simply select your war, click deploy, and watch your apps run - automatically, like magic!

As part of our Payara Cloud Closed Beta testing, we offered him a trial of the software. He created a concise video showing his experience using serverless MicroProfile and Jakarta EE on Payara Cloud. Watch it now to find out what his first thoughts were in his own words.  

How to Update An Application Using JAXB from JDK 8 to JDK 11

The Java Architecture for XML Binding (JAXB) framework is used to easily convert between XML and Java class instances.  You just have to define some annotations on the Java classes and properties and the framework uses those definitions to convert between them. But is also heavily used within the Java EE specification Java API for XML Web Services (JAX-WS) that implements the support for SOAP messages within Java Enterprise.

Are GlassFish and Payara Server the Same?

When commercial support for GlassFish ended in 2014, Payara Server was created from the open source code as a fully supported drop-in replacement for GlassFish.  

Payara Services was born in 2016 to offer support solutions for Payara Server. By 2017, Payara Services had joined The Eclipse Foundation and the Payara Platform expanded to include Payara Micro and comprehensive commercial support options for development projects, in-production support, and consultancy solutions.  New product features and the development of the Payara Platform evolves and is improved upon with each monthly release, and while the application server was originally derived from GlassFish and shares many similarities - the two products are not the same. 

New Webinar Series! Dismiss the Myths: Get to Know Jakarta EE

Last week, we announced our exciting new webinar series, 'Dismiss the Myths: Get to Know Jakarta EE (Java EE). This is a series of 6 webinars, every Wednesday at 3.00pm BST for the next 6 weeks - with the first one taking place this Wednesday! 

Our CEO and FounderSteve Millidge is leading this series, taking one common misconception about Jakarta EE ( previously Java EE ) at a time. Turns out, you might be wrong in thinking Java is behind the times...

This is also the perfect webinar series if you have heard Jakarta EE or Java EE mentioned but aren't sure what it is, what the namespace change means or where its future lies. Steve will be catering to users who are new to the technology as well as long-time Jakarta EE developers. 

Introducing the Payara Kubernetes Operator

When using Kubernetes, for more complex scenarios it is not enough to start the deployment or service. You also need to execute some commands within the containers to perform some configuration or initialization of the environment.

To automate configuration or the process of initializing an environment, you can write a Kubernetes operator.The Payara Kubernetes Operator, released as a Proof of Concept or Minimum Viable Product (MVP) in our June Payara Platform release, helps you to set up a Payara cluster using the Deployment Group feature of the Payara Server.

Do You Really Need Kubernetes?

These days, it seems Kubernetes is a topic that is never too far from people's lips.  The tool, and the associated tools built around it, are talked about so often it seems it's the only subject important to developers these days - especially as the IT world becomes increasingly orientated towards cloud and microservices.

But in spite of all the conversation around Kubernetes... do you really need Kubernetes for your environment? Or is it just another case of the next 'new and shiny' object,  with people distracted by the novelty and possibility, rather than the facts? In this blog, I'll take a closer look at why Kubernetes might be a case of the hype outweighing the helpfulness in most cases. 

Shape The Future of Payara Platform Through GitHub

Payara Platform is an open source middleware platform. This means that we are proud to nurture and grow an open and collaborative community, building on the needs of all to advance our software. 

Part of this ethos is inviting contributions to our software via our GitHub. Users can issue a pull request with suggested bug fixes and enhancements, and if successful, these will incorporated in our next release. We send t-shirts and stickers to contributors to say thank you! 

Since our last contributor shout out in February, we've implemented many useful pull requests, from valued long time contributors Alexander Pinchuk and Oliver Bertuch, as well as new contributorAngelTG2.

We also wanted to take the opportunity to point out that contributions aren't the only way to shape the future of Payara Platform. You can also up or down vote the open issues - new features, enhancements and bug fixes - that would make the most positive difference to YOUR development and applications. Find out more below. 

Introduction to New AutoScale Feature Available in Payara Server


Running your application sometimes requires multiple instances to handle the requests of the users. Within the Payara Platform, the Domain Data Grid helps you configure your environment to run your application in a cluster. Besides the setup of a cluster itself, many applications can benefit from an environment that scales dynamically.

The number of instances must increase when the application usage peaks and should decrease when activity is low to reduce the resource usage and the corresponding costs associated with it. The introduction of the AutoScale feature in Payara Server Community 5.2021.4  helps us achieve this dynamic scalability.

What's New in the June Payara Platform Release?

The June 2021 Payara Platform release is here!  Payara Enterprise 5.28.1 includes 5 bug fixes and 2 component upgrades along with a community contribution from AngelTG2 for improving loading time for REST applications when there are many password aliases.

In addition to the bug fixes, component upgrades, and community contribution improvement, the Payara Community 5.2021.4  release also introduces a new AutoScale feature in Payara Server to achieve dynamic scalability of instances based on application usage.

You can download Payara Platform Community 5.2021.4 here and request Payara Platform Enterprise 5.28.1here.

The Payara Monthly Catch for May 2021

The big community news of this month was the release of Jakarta EE 9.1! The Eclipse Foundation brought out Jakarta EE 9.1 Platform and Web Profile specifications and related TCKs - the first release since the breaking namespace change to jakarta. We've rounded up our articles & announcements on this subject below - and watch this space, as Payara Platform is very close to launching our own Compatible Implementation. 

We also released the results of our Payara Platform Survery 2021 . Read in fullhere, including what we've learnt about the infrastructure you are using with the Payara Platform, what features you want to see, and our findings on how our users are adopting MicroProfileAPIs and new Jakarta EE versions. 

We're already using the results of the survey to shape content that responds to recurring issues users are encountering. See Rudy'sblog on why you might be finding Payara Server slow and an easy fix you may not have tried, as issues with deployment speed was a common theme in our survey results. 

As well as Payara's own content, the 'Monthly Catch' also includes our pick of the best from Java EE/Jakarta EE, MicroProfile, Java SE and DevOps influencers and authors this month, and wider industry news. We hope you enjoy, and make sure you are following us onLinkedIn and Twitter, and signed up to our blog, to get this content as it comes! 

GlassFish 6.1 Should Not Be Used In Production: Here’s Why

Earlier this week, Jakarta EE 9.1 was released. This is an update to Jakarta EE 9, adding support for JDK 11 - you can read more about it in our bloghere.

Alongside the Jakarta EE 9.1 release, GlassFish 6.1 has been released as a Compatible Implementation

However, although GlassFish is still used by many - a legacy of the time it was supported by Oracle - we would argue it is NOT a good choice for running your enterprise applications in production.

If you are considering updating to more recent GlassFish versions, it might be better to consider more reliable, supported, and up-to-date alternatives. In this blog, I explain why GlassFish 6.x is not the best choice for your mission critical deployments.

Jakarta EE 9.1 Launches!

Payara Services are celebrating the release of Jakarta EE 9.1 Platform and Web Profile specifications and related TCKs.

With Jakarta EE 9.1, global source community Eclipse Foundation brings to Java developers the first incremental Jakarta EE release since the new namespace was introduced last year. Read the Eclipse Foundation announcement here - featuring a quote from our Founder and CEO Steve Millidge.

Payara's team have not only worked hard to ensure Jakarta EE 9.1 applications can be run in Payara Platform 5, but Payara Platform 6 alpha one is very close to being ready as a Compatible Implementation. Watch this space! 

Did You Know? If Payara Server Seems Slow, Try This

The 2021 Payara Platform Survey was completed in April. Our surveys help us shape the future of Payara Server and Payara Micro as they give us an idea what features and enhancements the community would like to see in future releases. Surveys also provide an opportunity for you to tell us what needs to improve and after finding 14% of respondents indicated the speed of deployment is not as fast as they would like, we wanted to share a tip.

Payara Micro 5によるUber JARの作成

Payara Microでは、Webアプリケーションを自己完結型で簡単に実行することができます。20165月のPayara Serverリリースからは、WARファイルの内容とPayara Microを構成するクラスやリソースを束ねる “Uber JAR” を作成する簡単な方法があります。

この “Uber” Jarは、Dockerコンテナ内でアプリケーションを実行するための最良の方法ではないことに注意してください。アプリケーションに小さなコード変更を加えるたびに、バイナリ全体のアップデートが必要になるためです。より良い方法は、Payara Microインスタンスを起動して、インストールが必要なアプリケーションを指定することです。詳細については Payara Micro Docker Image documentation をご覧ください。

Getting Started with Jakarta EE 9: Context And Dependency Injection (CDI)

In this series about getting started with Jakarta EE 9, we look at various specifications and how you can use them for your next application. In the previous blogs of this series, we set up our development environment and had a closer look at implementing REST endpoints.

This time, I will explain a few features of Context and Dependency Injection (CDI). The CDI specification is an important backbone of Jakarta EE as it brings several specifications together. Over the years, it became more and more important as an increasing number of specifications started using CDI as the basis for it.

In this blog, I will tell a bit about the different scopes, the interceptor mechanism, and the Event system.

6 Vital Steps to Enhancing IoT Security

You may have heard the term ‘Internet of Things’ or IoT, referred to with increasing frequency in technology and business circles. It is cited more and more frequently as key in the future of computing, the workplace, consumer technology, travel and more.

But what do we mean when we say Internet of Things – and what implications does it have when it comes to security?

How to Configure the HSTS Header on Payara

The HTTP Strict-Transport-Security response header (often abbreviated as HSTS) tells the browser that it should access the website only using HTTPS, instead of using HTTP.

The May 2021 releases of the Payara Platform, Community version 5.2021.3 and Enterprise version 5.28.0, allow you to configure the HSTS header.

カスタム SSL証明書を用いた Payara Serverのセキュア化

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。皆様は自己署名証明書または信頼できる認証局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。

The Payara Monthly Catch: April 2021

It's been an incredibly exciting month for Team Payara! We were honoured with a Queen's Award for Enterprise. This is the UK's most prestigious business award, often called the 'Knighthood for Businesses' and our award particularly recognises our international sucess. CEO and Founder Steve Millidge thanked the entire team in his blog, which also went more into detail about what this means for the wider Jakarta EE and MicroProfile community. 

In other Payara Services news, we're also 'buzzing' about our new Charity of the Year, the Bumblebee Conservation Trust - and see Payaran Lenny Primak below on Adam Bien's podcast, and Rudy De Busscher joining forces with IntelliJ IDEA! 

Community highlights included the release of the latest version of IntelliJ IDEA, with our engineersworking hard to update our Payara Platform pugins accordingly due to high demand from the community. We were also excited by news of the newMicrosoft Build of OpenJDK.

How to Use OpenIdConnect with Payara Platform to Achieve Single Sign-on

When a user needs to access multiple applications in your environment, you should not require authentication for each application. If the user has already been authenticated for one of the applications, he or she should  should not be asked for credentials when he accesses one of the other applications during the same browser session. This concept is called Single Sign-on where the authentication credentials are 'shared' in the environment and can be used by any application in that environment.

Getting Started with Jakarta EE 9: How to Create a REST API with Jakarta EE 9

In this second blog of the "Getting Started with Jakarta EE 9" series, we show you some basic scenarios using the REST specification. Although most people are using the term REST or RESTful API just to indicate they do data transfer over HTTP, and  ignore the "Hypermedia as the engine of application State (HATEOS)" part of REST. The technology is used a lot lately to connect the front-end with the back-end.

For those who are not familiar with Jakarta EE, this blog should give you an indication how to create such a REST API with Jakarta EE 9.

What's New in the Payara Platform April Release?

This month we release Payara Platform Enterprise 5.27.0 (request here) with 18 improvements and 3 new features, including an update to the previously released Upgrade Tool, an automated JBatch Job execution data cleanup feature, and the addition of a pluggable Notifier API with the ability to create your own notifiers.

The Payara Monthly Catch: March 2021

It's that time again, our March monthly catch! The "fishes" in our "net" are Java, Jakarta EE, Open Source and Microprofile articles, news stories, videos and podcasts we've found useful and interesting, as well as a few Payara Services updates.

Big news this month is the General Availability release of Java 16. Articles under the 'Java EE' subheading in our Community news section below provide expert opinions on what's new in this release.

Creating a Kubernetes Operator in Java: Foojay JUG Tour

Foojay's Virtual JUG tour is in full swing, with the Java community platform organising a succession of online events at JUGs all across the world. 

As contributors to the Foojay platform, supporters from the start and members of itsinaugural advisory board, Payara Services was happy to participate. Rudy de Busscher presented his talk, 'Creating a Kubernetes Operator in Java', for the St. Louis Java User Group as part of the tour.

You can now watch this, and also hear Geertjan Wielenga introduce the concept of Foojay to start the talk.

How to Connect Payara to External Hazelcast Grid

The Domain Data Grid feature of the Payara products is powered by the Hazelcast library. It provides the necessary functionality for the Deployment Group (clustering functionality), Cache functionality, CDI cluster singleton, and monitoring data storage within Payara to name just a few features.

Since Hazelcast can cluster multiple instances into a data grid, it is possible to create a Hazelcast grid that comprises the Payara instances and some other instances included in other applications running outside of Payara.

Debunking 6 Popular Myths About Edge Computing

‘Edge computing’ is a buzzword that has gained popularity over the years. The problem is the term  is applied quite broadly, and people use ‘edge computing’ to discuss a variety of topics. Sometimes, it’s spoken of in conjunction with the cloud; other times, with the Internet of Things or fog computing.

In 2018, Gartner suggested that less than 10% of enterprise-generated data was created using edge computing. However, this number is expected to reach 75% by 2025. 

This means businesses will soon put more emphasis on edge computing to process data as close to the source generating it as possible. With the increased importance of edge computing, it’s crucial we address a few misconceptions surrounding it.

We’ll start with six, but first…   

Getting Started with Jakarta EE 9: Hello World

Introduction

The release of Jakarta EE 9, at the end of 2020, was in many ways a historic event. The Java Enterprise framework is already 20 years old, having its first release in 1999. It has changed names a few times but the main concepts of the first release can still be found in this new release. During all those years, it has adapted itself to keep it up to date but has always adhered to its main principle of stability and backward compatibility.

Deploying to Payara Deployment Group Using the Maven Cargo Plugin

Introduction

The Apache Maven Cargo Plugin allows you to deploy your application to a Payara Server, running locally or remotely. Using Maven as a build tool is an easy way to immediately deploy the application during the build to a test or production server.

We have created a custom version of the Cargo Plugin which also supports the Deployment Group feature of the Payara Server.

Additional MicroProfile Config Sources Added in Payara Platform Enterprise 5.26.0

The March Payara Platform Enterprise Edition release (request here) includes 3 bug fixes, 4 improvements, and 7 additional MicroProfile Config Sources. You can see a more detailed overview of the fixes, improvements, and new features included in Payara Platform Enterprise Edition 5.26.0 in the Release Notes here.

Configuration of applications should not be done within the application itself, but externally. We’ve expanded the sources from where the configuration values could be read to support third-party configuration services and cloud providers in the March Payara Enterprise release:

The Payara Monthly Catch: February 2021

In our February Monthly Catch,  we’ve rounded up a wide range of the most useful learning materials, community news pieces, videos and podcasts from the world of Java, Jakarta EE and MicroProfile - and of course provided updates from Team Payara!

As we progress into the year, the new releases of Jakarta EE - including the breaking namespace change - and MicroProfile are becoming more embedded and discussed. For example, it was great to see Dalia Shea from JetBrains discuss using the new “jakarta” namespace, and Michael Redlich at InfoQ summarizing the JakartaOne conference where Jakarta EE 9 was officially announced.

We’re also seeing a lot of looking round the corner to what’s next for our community: to JDK 17, as well as the innovations coming through Project Loom and Project Panama.

It also seems to be unofficial survey season! We’ve launched our own, Omnifaces have published its survey’s fascinating results looking into JakartaEE and MicroProfile, and you still have time to answer questions forthe Snyk and Azul survey that came out this month. It’s exciting to see so many opportunities for people to feedback, drive and shape the future of Enterprise Java and its associated technologies.

Payara Community GitHub Policy

We’ve recently formalized our GitHub Policy for how we handle user requests for bug fixes and enhancements to ensure defects and bugs in the Payara Platform are discovered and addressed as soon as possible, and to give the community an opportunity to help decide which new features and product enhancements go into development.   

Below is a summary of the policy and how to get your questions answered, submit a bug report, or request an enhancement. You can read the complete Payara GitHub Policy here. 

Payara Cloud – So Easy Even the Marketing Team Could Use It

Payara Cloud Experiment Lab Report 

Introduction 

Before the Payara Cloud Closed Beta testing began we tried an experiment to see if Payara Cloud is as easy to use as we say it is by having a member of the marketing team (me!) test the product. I’ve been a copywriter/content writer specializing in technology topics for over 18 years, so while I can’t claim to be a stranger to the tech industry, my knowledge is more focused around the benefits of using certain types of technology rather than the inner details of how it works.  The idea of our little "science experiment" was if I could successfully deploy an application without any previous knowledge, then surely more experienced tech teams would find it even easier to use.

Payara Platform 2021 Survey

The Payara Platform 2021 Survey is underway and we're inviting everyone to answer a few questions about your use of the Payara Platform and ecosystem components. We want to know what you like, what you want to see improved, and we're giving you the opportunity to vote on new features you'd like to see added to the Payara Platform.

Cleanup JBatch Job Execution Data with New Asadmin Tool Command

The JBatch Jakarta EE specification describes the process of how background jobs can be executed on a Jakarta EE compatible runtime. Using the Batch Specification, the runtime can execute some jobs that don't require any user input. Most of the time they are scheduled to execute at a certain moment of the day, but they can be triggered on-demand.

Thank You Community Contributors - February 2021 Release

In what’s been a strange start to the year, a silver lining is the growth of innovative communities, with people pushing themselves to build something valuable together - making use of a time when the majority of us are in lockdown. At Payara Services, this has taken the form of an uptake in contributors to the Payara Platform open source project - and it’s time to say a huge thank you! 

The Payara Platform Community versions are open source runtimes for development projects and containerized Jakarta EE and MicroProfile. This means we welcome contributions through GitHub from developers looking to shape the future of Enterprise Java - whether to Payara Server Community, supporting Jakarta EE in any environment; or Payara Micro Community, which is lightweight to suit containerized Jakarta EE deployments.

Since our end of year Contributor shout-out, we’ve seen some fantastic pull requests on our GitHub, that have since been incorporated into this latest February release. 

Payara Services team members have worked with Payara Platform users to create the very best innovations, leading to mutual learning and development - and most importantly, ensuring that Payara Platform remains innovative, creative and agile. 

Use MicroProfile 4.0 Specs in Payara Platform Community 5.2021.1

In the December Payara Platform Community release, we added two MicroProfile specification release candidates for you to try out: the MP Health 3.0 and MP JWT Auth 1.2 specifications. (Read more about that in this blog: Test MicroProfile Specs in Payara Platform Community 5.2020.7 Release). In our February Payara Platform Community release, support for MicroProfile 4.0 is complete with the final versions of the MicroProfile specifications, and we are now pending compatibility recognition from the Eclipse Foundation.

 

What's New in the Payara Platform February Release?

This month we release Payara Platform Enterprise 5.25.0 (request here) with 4 improvements and 3 new features, including an update to the Upgrade Tool released last month that gives the ability to restore the domain configuration from the backup with the rollback-server command.

Meanwhile, the Payara Platform Community 5.2021.1 (download here) introduces support for the complete MicroProfile 4.0 specifications, a Hazelcast upgrade providing better support for Amazon AWS, improved stability of HTTP2, and a large number of community contributions. 

Don't miss our release overview virtual event next week, which is now open for registrations on Meetup here.

The Payara Monthly Catch: January 2021

It's time for the first Monthly Catch of the Year! We round up January's best content covering Java, Jakarta EE and MicroProfile - including tutorials, news stories, videos and podcasts. 

In the first month of 2021, many trusted experts made their predictions about what the year will look like for Enterprise Java. We’ve listed some of our favourites below, including the Payara team's own predictions. 

Make sure you watch our2021 Roadmap Webinar to find out how the big topics like OpenJDK 17 and the adoption of MicroProfile 4.0 will play out for the Payara Platform specifically, and shape our plans as a company over the next year. 

One hot-button that kept recurring in 2021 outlooks and in blogs was Project Loom. This incubation project is predicted to transform the way that multithreading works in Java, and has really generated a buzz this month, with several articles explaining and speculating on what the innovation, still in an experimental phase, will look like.  Will virtual threads make concurrency easier on the JVM?

Hide Passwords with Password Aliases in Payara Server

Introduction

When performing the configuration of the Payara Server for your application, you often need to supply a password. The password to connect to the database is a classic example, but there are many situations where you need to enter this kind of sensitive data.

With Payara Server, you have the option to hide this kind of sensitive data from the user, so that this information is much better secured.

How to Improve Domain Data Grid Performance (Japanese Language)

現在のPayara Platformアーキテクチャの基礎となるのは、ドメイン・データ・グリッドの採用です。ドメイン・データ・グリッドは複数のPayara ServerまたはPayara Microインスタンスを結合して、互いにデータを共有する交換可能なノードの堅牢なクラスタを形成し、クラスタにデプロイされたあらゆるアプリケーションに対して高可用性とフェールオーバー機能を提供します。

How to Improve Domain Data Grid Performance

One of the cornerstones of any modern Payara Platform architecture is the use of the Domain Data Grid. The Domain Data Grid allows multiple Payara Server or Payara Micro instances to join and form a robust cluster of interchangeable nodes that can share data between each other and grant High Availability and Failover capabilities to any applications deployed in the cluster. 

Payara Services Joins MicroProfile Working Group

Payara is pleased to announce that we have joined the MicroProfile Working Group. This builds on our commitment to shaping and improving Enterprise Java for both microservices and monolithic architectures. 

The MicroProfile project was born as a community initiative to optimise Enterprise Java with a microservices standard platform. It joined theEclipse Foundation in 2017, an independent open source software association, with the goal of driving innovation with a vendor-neutral "incubation" environment.

The Eclipse Foundation's MicroProfile Working Group encourages collaboration between participants, working in short cycles to propose and gain approval for new common APIs and functionality - and in turn drawing on the knowledge of a wide variety of different vendors. As one of the contributors, Payara engineers will shape and drive the future of the MicroProfile specifications.

We talked to our Founder and CEO Steve Millidge to find out more about what this means. 

Creating a Kubernetes Operator in Java

Kubernetes is much more than a runtime platform for Docker containers. Through its API you can not only create custom clients, but you can also extend Kubernetes. Those custom Controllers are called Operators and work with application-specific custom resource definitions.

How to Use Eclipse Transformer to Convert a 3rd Party Library to the New Jakarta Namespace (Japanese Language)

はじめに

Jakarta EE 9のリリースは、Java Enterpriseの伝統を破るものとなります。OracleからEclipse FoundationへのJava EEコード寄贈の法的な要件は、javax名前空間をjakarta名前空間に変更することです。

しかし、Jakarta EE 9でのパッケージとXMLの名前空間の変更はまだ始まりに過ぎません。名前空間の変更により、新たな開発や機能追加が可能となりましたが、Java Enterprise仕様の一部を使用しているフレームワークやライブラリもすべて新バージョンに合わせて調整する必要があります。

How to Use Eclipse Transformer to Convert a 3rd Party Library to the New Jakarta Namespace

Introduction

The release of Jakarta EE 9 breaks a tradition of Java Enterprise. A legal requirement of the Java EE code donation from Oracle to the Eclipse Foundation is the change of the namespace of javax to jakarta.


But the change of the package and XML namespace in Jakarta EE 9 is only the beginning. The change of the namespace allows for new development and functionality, but all frameworks and libraries using one of the Java Enterprise specifications also need to be adjusted to the new version.

The Payara Monthly Catch: December 2020

In December, the biggest news was Jakarta EE 9’s official release, completing the move to the jakarta namespace. This officially took place at the Eclipse Foundation Jakarta One Livestream, where our CEO Steve Millidge took part in the keynote speech (watch here) and presented as lead on the GlassFish project (video here). 

In other major release news, MicroProfile 4.0 was made available towards the end of the month, with the delayed release set to bring in new features including alignment with Jakarta EE 8. 

Payara has also enjoyed kick-starting healthy debate this month, with our CEO Steve Millidge proposing that Ahead of Time Compilation with GraalVM isn’t always all it’s cracked up to - and watching the comments roll in!  

We are hoping to continue to make bold statements and drive forward discussion in the Java and Jakarta EE community in 2021.

Improvements to Payara InSight in Payara Enterprise 5.21.1 Release

The Payara Enterprise Release 5.22.0 in October 2020 was the first Payara Enterprise release to include our fully integrated and greatly improved real-time monitoring and alerting solution called Payara InSight (formerly known as Payara Monitoring Console in Payara Community).

Then in the November 2020,release, we made improvements in how alerts are represented in the user interface, the display of widget content, and configuration options.

For December’s Payara Enterprise 5.21.1 (patch release), we’ve continued to make improvements that make Payara InSight easier to use. Updates include slight changes to the GUI for consistency and warning awareness, improvements in the flow of creating new pages, and improvements to the process of updating or changing a previously created Watch.

How to Develop Applications with Minimal Security Risks

When we develop software we don't expect to be hacked or compromised. We build great new software for the needs of our clients. The people that use our software expect that our systems are safe and data will not be compromised. To ensure that safety we need to take responsibility and develop our applications in such a way that we can meet these expectations. Since the situation is real that our application is hacked or compromised. In the guide below, we discuss 7 pointers that can help you develop applications with a minimal security risk.

Cloud Myth: Ahead of Time Compilation Will Save You Money

There is a lot of interest in the server-side Java community around using ahead of time (AOT) native compilation provided by Graal Substrate VM to drive down memory usage and cold start times of Java microservices. While these frameworks are technically interesting, the claim is if you spend time rewriting your Jakarta EE applications to utilise these new frameworks, then you will substantially reduce your cloud operational costs. First, by enabling the adoption of a serverless deployment model and second by reducing your containers' memory usage. 

Test MicroProfile Specs in Payara Platform Community 5.2020.7 Release

As MicroProfile moves toward the 4.0 final release, the Payara team has simultaneously been working to ready the Payara Platform for MicroProfile 4.0 compatibility. One of the goals of the Payara Platform Community Edition is to evolve rapidly and provide a place for developers to test new features and capabilities as soon as they are available. In the Payara Platform Community 5.2020.7 Release, you can give two of the MicroProfile specification release candidates a try: MP Health 3.0 and MP JWT Auth 1.2.

What's New in the Payara Platform December Release?

The last Payara Platform release of 2020 is here!  With this patch release of Payara Platform Enterprise 5.23.1, we're introducing more improvements and component upgrades to Payara InSight as well as a couple useful bug fixes. Meanwhile, the Payara Platform Community 5.2020.7 introduces some improvements and additions to the MicroProfile specs in preparation for the upcoming MicroProfile 4.0 release. We are also happy to confirm that Payara Platform Web Profile is now Jakarta EE 8 compatible!

You can download Payara Platform Community 5.2020.7 here and request Payara Platform Enterprise 5.23.1 here.

Payara Services Celebrates the Release of Jakarta EE 9

As leading contributors to the Jakarta EE project, Payara excitedly welcomes Jakarta EE 9 - now officially released! 

Announced at today’s Jakarta One Livestream, the headline breaking change is the move from the package namespace javax to jakarta across the Jakarta EE 9 Platform, Web Profile specifications, and related TCKS. 

Through our involvement in the Eclipse Foundation Jakarta EE Working Group, we are proud to play a major role in shaping, improving and championing Jakarta EE 9. The specifications will be key to the evolution of cloud native technologies for Java, also central to Payara's mission. 

MicroProfile, Your Cloud-Native Companion for Enterprise Java

Writing microservices within Jakarta EE is technically possible, but you miss a few goodies for the distributed environment you are running in.

MicroProfile wants to optimize your Enterprise Java application by creating Java standards which link to some well known CloudNative standards like etcd for Configuration, OpenTracing and Jaeger for Distributed Tracing and Prometheus for Metrics.

In this talk, delivered by Payara's Rudy De Busscher at EclipseCon, he goes over some basic concepts of the MicroProfile specifications and show you through various demos how the integration with those tools can be done easily.

The Payara Monthly Catch from November 2020

The big news from this month was the General Availability release of Jakarta EE 9 on November 20th, moving to the jarkarta namespace once and for all. This will be followed by an official release at the Eclipse Foundation's JakartaOne Livestream on December 8th - at which our Founder Steve Millidge is a key speaker. You can register to attend here
 
It's also been a month of exciting news for Payara as a business, as we've extended our partnership with Azul Systems and taken key steps towards beta testing of our exciting Payara Cloud project, all alongside our regular monthly platform release. We've also been excited to see Payara used as examples in Community materials such as Otávio Santana , Geovanny Mendoza, and Aristides Bravo's new Jakarta EE guide, in various learning materials and blogs, and in a Microsoft tutorial!

10 Strategies for Developing Reliable Jakarta EE Applications for the Cloud

What happens when an application designed for a small user base needs to be scaled up and moved to the cloud?

It needs to live in a distributed environment: responding to an appropriate number of concurrent user requests per second and ensuring users find the application reliable. 

Though Jakarta EE and Eclipse MicroProfile can help with reliable clustering, there is no standard API in Jakarta EE that defines how clustering should work currently. This might change in the future, but in the meantime, this gap must be filled by DevOps engineers.

In this blog, we will cover 10 technical strategies to deal with clustering challenges when developing Jakarta EE and MicroProfile for cloud environments.

Behind the Scenes: Payara Cloud Development

If you haven't heard yet, the Payara Team has been hard at work developing Payara Cloud, The Next Generation of Cloud-Native Application Server. Payara Cloud makes it easier to run your applications on the cloud - and eliminates the need to learn how to use Kubernetes. With Payara Cloud, you simply select your war, click deploy, and watch your apps run on the cloud, automagically!  (Have you seen the Payara Cloud teaser video yet? Take a look here.) 

OpenAPI Refactor Added to Payara Platform Enterprise 5.23.0 Release

Payara Platform Enterprise users will be pleased to hear that we released a refactor of the MicroProfile OpenAPI implementation we provide in Payara Platform Community 5.2020.3 with the aim of addressing a number of issues and requests that had been raised over time. The original blog, detailing some of these features, can be found here

OpenAPI Refactor has now been included in the Payara Platform Enterprise 5.23.0 release.

Payara InSight Improvements in Payara Server Enterprise 5.23

In Payara Server Enterprise 5.23 we continued improving our monitoring solution released in Payara Server Enterprise 5.22.0 (read about it here) called Payara InSight. The main focus of improvements for this release is the representation of alerts in the user interface. We also had a closer look at how widget content is arranged and coloured which also lead us to add further configuration options.

Eclipse MicroProfile Enhancements in Payara Server Community 5.2020.6

The Payara Server Community 5.2020.6 release introduces a host of new enhancements to Eclipse MicroProfile, with MicroProfile Config containing most of these improvements. MicroProfile Config now comes with five new config sources for cloud key vaults and databases. The Payara Health Check Service has also been updated to monitor any Metrics exposed in the MicroProfile Metric, and it can now expose any HealthCheck checkers to the MicroProfile Health REST endpoints.
