Hashtag Jakarta EE #238

Welcome to issue number two hundred and thirty-eight of Hashtag Jakarta EE!

I have just arrived back home from JConf Dominica 2024, and have a couple of hours to pack my bags before heading out again for JCrete 2024. Busy times for a developer advocate, but so incredibly great to be able to connect with the Java communities all over the world.

(I don’t know if it was pure luck, or if the stars were aligned just right for me this time, but as it turned out, the only two days I was on the ground this week were the two days with Blue Screen of Death for the airlines.)

The first release candidate of Jakarta EE 11 will be published shortly. There are a couple of the specifications that have released service releases of their API artifacts, so we will gather these and release an RC1 of the Jakarta EE 11 APIs.

All the Jakarta EE 11 XML Schemas are publicly available at https://jakarta.ee/schemas/. Please check them out and let us know if you find something that needs to be corrected before the release is Final.

Another way of providing input, AND possibly winning a FREE T-shirt is to complete the 2024 Cloud Native Java Technical Survey.

JConf Dominicana 2024

A Java conference in the Dominican Republic sounds too good to be true. Well, I can tell you that it is a thing, and it is awesome! JConf Dominicana, The Caribbean Java Technologies Conference is organized by Java Dominicano, the Dominican Java User Group. It is a one-day conference with a half day of workshops the day before.

I hosted a 4-hour Jakarta EE workshop together with Eudris Cabrera. He provided Spanish translations of all the instructions for the participants and explained in Spanish where my English came short. We had a great time, and it looks like the participants enjoyed it as well if you judge from the happy faces in this photo.

Jakarta EE was very well represented at JConfDominicana this year. In addition to the workshop, Shabnam did a keynote titled Empowering Innovation: The Open Source Odyssey of Contribution and Collaboration with Jakarta EE.

The day before the conference, we went out to explore the city and ended up visiting a cigar factory where they had free tours of the facilities. It is amazing to see how cigars are hand-made this way. Our clothes will need a turn in the washer after the visit as almost everyone in there was smoking cigars while working.

It is always such a great experience to speak at conferences like JConfDominica that are organized by and for the local Java Community. I encourage everyone who employs Java developers anywhere in the world to support the local Java community.

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

After a couple of weeks at home, I am going on the road again. First off is JConfDomincana, the Caribbean Java Technologies Conference organized by the Dominican Republic Java User Group, where I will host a workshop together with Eudris. The topic of the workshop is creating RESTful Web Services with Jakarta EE.

As mentioned in last week’s Hashtag Jakarta EE, the refactoring of the Jakarta EE TCK is what we are waiting for to be able to release Jakarta EE 11. The TCK project has now set up a Jakarta EE 11 TCK Release GitHub Board where we can follow the progress of this work.

I also mentioned that the Jakarta EE Platform project has started planning for Jakarta EE 12. To facilitate this planning, we would really like to have YOUR which you can provide by completing the 2024 Cloud Native Java Technical Survey. Note that this survey is different from the Jakarta EE Developer Survey we conducted earlier this year.

The program for Open Community for Java will be published in the upcoming week. Meanwhile, you can check out the featured speakers and why not just register while you’re at it? The conference is in Mainz, Germany October 22-24.

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

Last week I was speaking at Developer Week’24 in Nuremberg, Germany. That was my last conference of the European conference season before summer. This year, there will be a couple of conferences during the summer before the fall season start up. In a couple of weeks, I will host a workshop at JConfDominica 2024 before going directly to Greece for JCrete 2024.

Jakarta EE 11 is almost ready. All the individual specifications are done, and the Jakarta EE Platform project is finalizing the Jakarta EE Platform, Web Profile, and Core Profile specifications. The last piece of the puzzle is the work with the Jakarta EE TCK which is being refactored from Apache Ant and JavaTest Harness to a more modern approach using Apache Maven, JUnit 5, and Arquillian.

In parallel to this work, the platform project has started the discussions for a Jakarta EE 12 release sometime in the first half of 2026 with a baseline of Java 21 and verified with compatible implementations passing the TCK on Java 21 and Java 25. Note that these are very preliminary discussions and subject to change.

The program for Open Community for Java that will take place in Mainz from October 22 to 24 this year will soon be available. Take a look at the early-bird selection of speakers while waiting for the rest of the program to be published. From what I hear, the notifications to accepted speakers will be sent out this week.

Developer Week ’24

Developer Week is a four-day conference that takes place in Nuremberg, Germany. As the name implies, it is a developer conference where Java is a track among the other track topics. I spoke at the conference for the first time in 2017, and it feels like the Java track has increased in size since then even if it is still a small part of the conference. Anyway, it is very useful to be present at these non-100%-Java conferences as well. As Brian pointed out, they are coping with the same problems and challenges as the Java community. Talking about Brian, here we are as we are following Jonathan‘s presentation.

Jonathan brought his daughter with him on this trip, and she go the task of evaluating the various speakers’ presentation skills. It will be interesting to see how well I perform on stage in the eyes of a 14-year-old girl. Hopefully, my bribe in the form of some exclusive Jakarta EE swag will improve my evaluation.

My talk From Spring Boot 2 to Spring Boot 3 with Java 22 and Jakarta EE went well. I even demoed Jakarta Data at the end of the talk.

Before the conference day, I went for a morning run around Nürnberg. there is a nice walk/bike path on the outside of the old city walls that is perfect for running.

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

As I wrote last week, all the Jakarta EE 11 specifications are now finished and the remaining work to get Jakarta EE 11 released is to finalize the refactoring of the TCK and have at least one open-source compatible implementation passing it.

Milestone 4 of the Jakarta EE 11 APIs are now available in Maven Central. Use these coordinates in your pom.xml to try out this version.

<dependency>
    <groupId>jakarta.platform</groupId>
    <artifactId>jakarta.jakartaee-api</artifactId>
    <version>11.0.0-M4</version>
    <scope>provided</scope>
</dependency>

I will go to Nürnberg to speak at Developer Week ’24 this week. It will be my fourth time speaking at this conference, including one online appearance during the pandemic. It does not usually gather the biggest Java crowd, but it feels like the number is increasing for each year. The conference is well-run and a very pleasant experience.

Talking about conferences, the registration for Open Community for Java is now open. If you know you are going, or usually used to attend EclipseCon, you may as well register now. The program is being finalized as we speak and you will be able to check out the speakers and their talks very soon.

Register for Open Community for Java today!

Now that all the specifications for Jakarta EE 11 are done, the specification projects are starting to look ahead to Jakarta EE 12 and how to further evolve the specifications. It is great to see the individual projects taking the initiative this way.

This week was dedicated to the Eclipse Foundation All Hands 2024. In the upcoming week, I will be at home before I go to Nürnberg to speak at Developer Week in the first week of July.

Eclipse Foundation All Hands 2024

UPDATED: It was pointed out to me by Rosaria that I had missed including the picture of us about to go kayaking in my post. This obviously had to be corrected! Scroll down to the bottom of the post to read about #kayakingWithJakartaEE.

Once a year, the Eclipse Foundation comes together at the same location to socialize, learn, and exchange experiences with each other. As a fully remote organization, these events are even more valuable than those for organizations where you meet your colleagues at the office every other day.

In this photo below, you can see the Community and Outreach team which I am a part of. We missed a couple of colleagues who couldn’t make it, otherwise, the picture is complete.

In addition to staff training sessions and interesting presentations from the various parts of the Eclipse Foundation, there was also time for socializing, having fun, and enjoying excellent food. Here is a video of the early morning runners on the trail in a Quebecian forest. I take pride in slowly increasing the number of runners with the #runWithJakartaEE shirts every year.

There were activities for everyone from yoga on the beach, kayaking, hiking, swimming, or just hanging out in the pool or the surrounding area. The last night ended with a bonfire where those who wanted could get their s’mores. And there was cake…

Kayaking with Jakarta EE

As mentioned above, one of the activities was to go kayaking. Since I have very limited experience in kayaking, I was very pleased when Rosaria agreed to be my partner in crime for this activity. She is a natural. Even if I was appointed captain of the ship, mostly due to the weight balance I guess, she was the one steering it. You have earned a Jakarta EE t-shirt, Rosaria! And also the first to be tagged with #kayakingWithJakartaEE.

DevBCN 2024

My second trip to Barcelona in less than two weeks was to DevBCN. This community-driven conference is always a pleasure to speak at. And it doesn’t hurt that it is located in Barcelona…

This time we had an Eclipse Foundation booth staffed by Carmen, Arjan, and yours truly. We even had some new Jakarta EE swag in the shape of caps and sunglasses. A fun moment was to have a selfie with Jean-Fredric from the ASF where he was wearing his vintage jakarta.apache.org t-shirt and me with my Jakarta EE t-shirt.

Despite some issues with the screens, I was able to start my talk at the scheduled time. This time, I dusted off the popular From Spring Boot 2 to Spring Boot 3 with Java 22 and Jakarta EE talk. Every time I do this talk, the number of attendees raising their hand when I ask who that has already done the migration is increasing. A bit surprising this time was that there were more hands raised for “not started yet”. So the talk is still valid, and I will most likely continue presenting it for a while longer.

Originally, I was supposed to do the one talk this year, but since there were cancelations from some speakers not being able to come, I was asked if I could do a second talk. The one I chose to do was an update of what to expect from Jakarta EE 11, and how this release will help you boost both performance and developer productivity.
