Jakarta EE

New York Java SIG 2025

Yesterday, I had the pleasure of visiting New York Java SIG as the first stop of my mini-tour of US North East Java User Groups. Around 20 members showed up for my presentation titled Jakarta EE Meets AI. It was my first time presenting at the New York Java User Group, but I certainly hope it won’t be the last.

Eclipse Foundation sponsored the pizza of the event as a part of our newly created Open Community Events program. My task before the event was to pay for the pizza order. Since security around credit cards have been increased over the years, it was not possible to do this over the phone with the pizzeria. So I put on my running shoes and Jakarta EE socks for a morning run all the way from Times Square to Financial District. A decent 12 km #runWithJakartaEE run to start off the day. On Wednesday morning, I also did a run in Central Park before boarding my train to Hartford, CT, for the second stop on the tour.

Welcome to issue number two hundred and sixty-nine of Hashtag Jakarta EE!

Last week, I spoke at the Madrid JUG. We also had a panel where my colleagues at the Eclipse Foundation talked about the work they do to support the open-source community. Next week, I will go on a North East US JUG tour where I will speak at NYJavaSIG, Connecticut JUG, and Boston JUG. If you’re in the area, I hope you will come and say hello and have some pizza.

I know that I have been saying this for a while now, but the release of Jakarta EE Web Profile 11 is very close. There are only some small refinements remaining for the TCK to be fully refactored and ready to be used for certifications.

I also want to remind you to register for Devnexus. As in the previous years, we will have a whole track dedicated to content related to Jakarta EE. Check it out in the schedule.

Madrid JUG 2025

The Madrid JUG is organised together with the Madrid Groovy User Group. It is a great idea to combine user groups of similar tech areas, both for increasing attendance as well cross-pollinating between communities.

The event started with my presentation titled Boost Performance and Developer Productivity with Jakarta EE 11. After that, the program managers present had a panel led by Carmen where they explained what they are doing in the Eclipse Foundation to foster the open source community. It is not often that we are able to be this many representatives from Eclipse Foundation at a community event, so it was a special evening. The turnout was great, and we had good talks and discussions over pizza and drinks after the presentations.

I have done this presentation several times over the last year, but it is never the same as it keeps evolving. The slides contains more and more material for Jakarta EE 12 as the planning for the release progresses.

While the last pieces of the Jakarta EE 11 TCK are being put together, the topic of Jakarta EE 12 is really getting some traction in the Jakarta EE Platform Project. It is great to see the discussions around Jakarta Config as well as several other specifications and areas for this release. The Jakarta NoSQL project is polishing up the material for its release review, which should be ready to go pretty soon. This is a major milestone for the project! Jakarta Data has produced all the material for a plan review, so the project is in a very good state for Jakarta EE 12. Check out the issues labeled for Jakarta EE 12 in the Jakarta EE Platform issue tracker.

After a couple of months with holiday break, vacation, and conference low-season, I will now get on the road again. First up is the Madrid JUG on Tuesday next week. I look forward to getting out where the community is.

Welcome to issue number two hundred and sixty-seven of Hashtag Jakarta EE!

I am still enjoying time off in Indonesia, but will be back in business again this week. I am happy to see the Jakarta Config specification is finally gaining some momentum again. This is a specification we wanted included first in Jakarta EE 10, and then in Jakarta EE 11. Now it looks like Jakarta EE 12 will be where it is finally made available to the Jakarta EE developers.

After coming back home, I will fairly quickly go on the road again to visit a couple of Java User Groups before the major conferences starts. First out will be Madrid, followed by New York, Connecticut, and Boston. Check out these and more events on my Jakarta EE Developer Advocate page.

Welcome to issue number two hundred and sixty-six of Hashtag Jakarta EE!

I am on vacation in Indonesia this week, so this post will be a tad shorter than usual.

Java is always close. Right now closer than ever for me since it is just over the horizon. Jakarta is there on the other side as well, so I make sure to wear all the appropriate Jakarta EE branded gear while walking along the beach. So far, nobody has made any comments, though…

If you never experience the need to look up the term Bali Belly, you should consider yourself lucky.

The work with Jakarta EE 11 continues, I keep an eye on the activity on the various lists and forums even when I am not actively participating. Maybe Web Profile will be releases when I come home…?

Welcome to issue number two hundred and sixty-five of Hashtag Jakarta EE!

Here’s some good news! The Jakarta NoSQL project is ready to release version 1.0 of the specification. At the moment, they are putting together the last bits and pieces of the material required for the release review by the Jakarta EE Specification Committee. You can look at it in the pull request for that purpose. It is a big milestone for a Jakarta specification project to release the first version of a specification. Congratulations to the team!

As for Jakarta EE 11, the Jakarta EE TCK project members continue their efforts to finalize the Jakarta EE Web Profile 11 TCK. There are just a couple of tests remaining and the focus is currently on updating the TCK User Guide for the refactored way of running the tests. You can follow their progress on their GitHub Project Board.

I will be on vacation for the next few weeks but don’t despair. As usual, I will monitor the progress and publish Hashtag Jakarta EE every week.

Javaforum Malmø 2025

It has been a goal for a very long time to have at least one Javaforum Malmö event each quarter of the year. We didn’t manage that last year, but hopefully 2025 is the year when we are back on track.

It certainly started well with more than twenty people attending the event on this Monday in January. The main act of the day was Johannes Bechberger with a brand new talk titled Sound of Scheduling: Writing Linux Schedulers in Java with eBPF.

The talk is pretty technical, some would probably say nerdy, about how to create Linux schedulers with Java and eBPF. Probably not something the majority of us would even attempt, but awesome to watch Johannes take us through the process. Adding sound to the scheduler was a nice addon, and particularly great for a presentation to attract the interest of the audience.

After the talk, the conversation continued while we enjoyed pizza and drinks. This socializing aspect of a JUG is just as important as the presentation itself. This is where Java developers get to meet and talk with other Java developers outside of their daily workplace or project.

Last, but not least, thanks to Foo Café for hosting us and providing food! Make sure to check out their other events on their events page. This is also where we announce our events, so keep an eye on this page. As always, if you are interested in speaking at Javaforum, don’t hesitate to reach out and tell us.

Welcome to issue number two hundred and sixty-four of Hashtag Jakarta EE!

The latest news about the refactoring of the TCK for Jakarta EE 11 is that the team is getting closer to releasing Jakarta EE Web Profile 11. There are just a small number of tests remaining to be refactored, and the rewriting of the TCK User Guide has started.

The discussions around Jakarta EE 12 are gaining momentum. Check out the EE12 labeled issues in the Jakarta EE Platform GitHub Issue Tracker. Feel free to add new issues or contribute to the discussions of those already created.

You can also join the Jakarta EE Future Directions interest group and participate in high-level discussions about how the platform should evolve. If you’re not able to join the bi-weekly calls (calendar), you can always join the mailing list and participate there as well.

On Monday, I will host the first event in Javaforum Malmø of 2025. The event will be at Foo Café. This time, we will have Johannes Bechberger presenting how to write Linux schedulers in Java with eBPF.

Welcome to issue number two hundred and sixty-three of Hashtag Jakarta EE!

Jakarta EE Core Profile 11 was released in December. You can check out all the details on the updated Jakarta EE Core Profile 11 specification page. The next out will be Jakarta EE Web Profile 11, which will be released as soon as there is a compatible implementation that passes the refactored TCK. The Jakarta EE Platform 11 will follow after the Web Profile.

To use Jakarta EE Core Profile 11, simply add the following dependency to your application and run it with a Jakarta EE 11 Core Profile 11 compatible runtime.

<dependency>
    <groupId>jakarta.platform</groupId>
    <artifactId>jakarta.jakartaee-core-api</artifactId>
    <version>11.0.0</version>
    <scope>provided</scope>
</dependency>

January is traditionally a calm month for conferences, but also probably the busiest period for call-for-papers. Most of the conferences coming up in the next 6-9 months have CPPs open now. Make sure to check out my Jakarta EE Developer Advocate page to check out my upcoming speaking engagements.

Even this year, we will have a track at Devnexus entirely dedicated to Jakarta EE content. Check out the talks, and go ahead with your registration. You don’t want to miss out on Devnexus! This year will be even more special with the celebration of Java’s 30th anniversary.

But you don’t have to wait until the next conference to get Jakarta EE content. Check out the sessions from JakartaOne Livestream 2024 on the Jakarta EE YouTube channel.
