With the recent release of JakartaEE9, the future for Java has never been brighter. In addition to headline projects moving forward into the new jakarta.* namespace, there has been a tremendous amount of work done throughout the community to stay at the forefront of the changing landscape. These efforts are the summation of hundreds of hours by just as many developers and highlight the vibrant ecosystem in the Jakarta workspace.

The Jakarta EE contributors and committers came together to shape the 9 release. They chose to create a reality that benefits the entire Jakarta EE ecosystem. Sometimes, we tend to underestimate our influence and the power of our actions. Now that open source is the path of Jakarta EE, you, me, all of us can control the outcome of this technology. 

Such examples that are worthy of emulation include the following efforts. In their own words:

Eclipse Jetty – The Jetty project recently released Jetty 11, which has worked towards full compatibility with JakartaEE9 (Servlet, JSP, and WebSocket). We are driven by a mission statement of “By Developers, For Developers”, and the Jetty team has worked since the announcement of the so-called “Big Bang” approach to move Jetty entirely into the jakarta.* namespace. Not only did this position Jetty as a platform for other developers to push their products into the future, but also allowed the project to quickly adapt to innovations that are sure to come.

[Michael Redich] The Road to Jakarta EE 9, an InfoQ news piece, was published this past October to highlight the efforts by Kevin Sutter, Jakarta EE 9 Release Lead at IBM, and to describe the progress made this past year in making this new release a reality. The Java community should be proud of their contributions to Jakarta EE 9, especially implementing the “big bang,” and discussions have already started for Jakarta EE 9.1 and Jakarta EE 10. The Q&A with Kevin Sutter in the news piece includes the certification and voting process for all the Jakarta EE specifications, plans for upcoming releases of Jakarta EE, and how Java developers can get involved in contributing to Jakarta EE. Personally, I am happy to have been involved in Jakarta EE having authored 14 Jakarta EE-related InfoQ news items for the three years, and I look forward to taking my Jakarta EE contributions to the next level. I have committed to contributing to the Jakarta NoSQL specification which is currently under development. The Garden State Java User Group (in which I serve as one of its directors) has also adopted Jakarta NoSQL. I challenge anyone who still thinks that the Java programming language is dead because these past few years have been an exciting time to be part of this amazing Java community!

WildFly 22 Beta1 contains a tech preview EE 9 variant called WildFly Preview that you can download from the WildFly download page.  The WildFly team is still working on passing the needed (Jakarta EE 9) TCKs (watch for updates via the wildfly.org site.)  WildFly Preview includes a mix of native EE 9 APIs and implementations (i.e. ones that use the  jakarta.* namespace) along with many APIs and implementations from EE 8 (i.e. ones that use the  java.* namespace). This mix of namespaces is made possible by using the Eclipse community’s excellent Eclipse Transformer project to bytecode transformer legacy EE 8 artifacts to EE 9 when the server is provisioned. Applications that are written for EE 8 can also run on WildFly Preview, as a similar transformation is performed on any deployments managed by the server.

Apache TomEE is a Jakarta EE application server based on Apache Tomcat. The project main focus is the Web Profile up until Jakarta EE 8. However, with Jakarta EE 9 and some parts being optional or pruned, the project is considering the full platform for the future. TomEE is so far a couple of tests down (99% coverage) before it reaches compatibility with Jakarta EE 8 (See Introducing TCK Work and how it helps the community jump into the effort). For Jakarta EE 9, the Community decided to pick a slightly different path than other implementations. We have already produced a couple of Apache TomEE 9 milestones for Jakarta EE 9 based on a customised version of the Eclipse Transformer. It fully supports the new jakarta.* namespace. Not to forget, the project also implements MicroProfile.

Open Liberty is in the process of completing a Compatible Implementation for Jakarta EE 9.  For several months, the Jakarta EE 9 implementation has been rolling out via the “monthly” Betas.  Both of the Platform and Web Profile TCK testing efforts are progressing very well with 99% success rates.  The expectation is to declare one (or more) of the early Open Liberty 2021 Betas as a Jakarta EE 9 Compatible Implementation.  Due to Open Liberty’s flexible architecture and “zero migration” goal, customers can be assured that their current Java EE 7, Java EE 8, and Jakarta EE 8 applications will continue to execute without any changes required to the application code or server configuration.  But, with a simple change to their server configuration, customers can easily start experimenting with the new “jakarta” namespace in Jakarta EE 9.

Jelastic PaaS is the first cloud platform that has already made Jakarta EE 9 release available for the customers across a wide network of distributed hosting service providers. For the last several months Jelastic team has been actively integrating Jakarta EE 9 within the cloud platform and in December made an official release. The certified container images with the following software stacks are already updated and available for customers across over 100 data centers: Tomcat, TomEE, GlassFish, WildFly and Jetty. Jelastic PaaS provides an easy way to create environments with new Jakarta EE 9 application servers for deep testing, compatibility checks and running live production environments. It’s also possible now to redeploy existing containers with old versions to the newest ones in order to reduce the necessary migration efforts, and to expedite adoption of cutting-edge cloud native tools and products.

Amelia Eiras] Pull Request 923- Jakarta EE 9 Contributors Card is a formidable example of eleven-Jakartees coming together to create, innovate and collaborate on an Integration-Feature that makes it so that no contributor, who helped on Jakarta EE 9 release, be forgotten in the new landing page for the EE 9 Release. Who chose those Contributors? None. That is the sole point of the existence of PR923.I chose to lead the work on the PR and worked openly by prompt communications delivered the day that Tomitribe submitted the PR – Jakarta EE Working Group message to the forum to invite other Jakartees to provide input in the creation of the new feature. With Triber Andrii, who wrote the code and the feedback of those involved, the feature is active and used in the EE 9 contributors cards, YOU ROCK WALL

The Integration-Feature will be used in future releases.  We hope that it is also adopted by any project, community, or individual in or outside the Eclipse Foundation to say ThankYOU with actions to those who help power & maintain any community. 

  • PR logistics: 11 Jakartees came together and produced 116 exchanges that helped merge the code. Thank you, Chris (Eclipse WebMaster) for helping check the side of INFRA. The PR’s exchanges lead us to choose the activity from 2 GitHub sources: 1) https://github.com/jakartaee/specifications/pulls all merged pulls and 2)  https://github.com/eclipse-ee4j all repositories.
  • PR Timeframe: the Contributors’ work accomplished from October 31st, 2019 to November 20th, 2020, was boxed and is frozen.   The result is that the Contributor Cards highlight 6 different Jakartees at a time every 15 seconds.  A total of 171 Jakartee Contributors (committers and contributors, leveled) belong to the amazing people behind EE 9 code. While working on that PR, other necessary improvements become obvious. A good example is the visual tweaks PR #952 we submitted that improved the landing page’s formatting, cards’ visual, etc. 

Via actions, we chose to not “wait & see”, saving the project $budget, but also enabling openness to tackle the stuff that could have been dropped into “nonsense”. 

 

In open-source, our actions project a temporary part of ourselves, with no exceptions. Those actions affect positively or negatively any ecosystem. Thank you for taking the time to read this #SharingIsCaring blog.
