J-FALL is the biggest Java conference in the Netherlands. The 2023 edition was the 20th edition and had 1800 attendees registered. It is impressive for a one-day conference! The conference is organized by NLJUG (Nederlandse Java User Group) and is free for members of the JUG.
The venue for the conference is Pathé Ede, which is a cinema complex situated in Ede, about an hour’s train ride from Amsterdam. The speaker lineup was impressive, as always, covering a wide range of topics.
My talk was titled Prepare for Jakarta EE 11. As the title indicates, it is an overview of what’s coming in Jakarta EE 11. I also gave a demo of Jakarta Data, the newest addition to Jakarta EE.
J-FALL is one of my favorite conferences, and this was my fourth consecutive time speaking there. It is such a great community around it. Hopefully, I will be back next year and many more years to come…
The upcoming week will be busy with three talks at two conferences. I will attend Øredev 2023 here in Malmö on Wednesday before heading to Ede to speak at J-Fall on Thursday. The talk is titled Prepare for Jakarta EE 11 and will provide an update on what to expect from that release.
On Friday, I will be back at Øredev where I have two talks. The first one is the talk where I show how to handle the javax.* to jakarta.* namespace change when migrating from Spring Boot 2 to Spring Boot 3. The second talk is titled How to Be a Responsible Open Source Citizen which will give some pointers to how to navigate the different open source projects and communities, and hopefully inspire new open source contributors.
Those of you who have followed us throughout the years know that we always have a theme contest of some edible sort. Previous editions have featured cupcakes, cakes, pizzas, and cheese. I am not going to reveal this year’s theme, other than hint about it being sweet and delicious…stay tuned for updates!
I’ve always been a big fan of Donald Duck, and I still have a subscription so each week a new issue of Kalle Anka (that’s what Donald is called in Sweden) is delivered to my mailbox.
Since I have been on the road for the better part of October, I have a lot of unread magazines to enjoy until the next travel.
It was quite a puzzle to fit in four conferences in four countries on three different continents within three weeks. But luckily, all flights were on schedule and the entire journey went without any mishap at all. Even short connections at Charles de Gaulle and Casablanca Mohammed V airports worked as clockwork.
The work with Jakarta EE 11 continues. Check out the minutes from the weekly Jakarta EE Platform calls to stay up-to-date. Or, if you can fit it into your calendar, consider joining the calls to get the information first-hand. The call is happening on Tuesdays at 11:00 a.m. Eastern Time. Information on how to join can be found in the Jakarta EE Specifications Calendar.
One of the outcomes of EclipseCon is to start the work of producing SBOMs for the projects involved in Jakarta EE 11. Take a look at the pull request for a proposed way of doing it in parent pom.xml for all EE4J projects. More about this later.
One of the aspects that make EclipseCon special to me is that it is an opportunity to meet and socialize with my Eclipse Foundation colleagues. Since we are a distributed organization, EclipseCon is one of the few opportunities during a year that we can meet face-to-face. While it is not the primary objective of the conference, it is a very good add-on.
Day 3 of EclipseCon 2023 was a bit quieter than the previous ones. I guess some of the attendees returned home early after a couple of intense conference days.
Emily and I hosted a panel session about MicroProfile and Jakarta EE. Since the two of us were the only panelists, it turned into a dialogue on stage. In my opinion, this format works much better than a normal panel session with a moderator and all that comes with it. After a short introduction about what to expect from the next releases of Jakarta EE and MicroProfile, we started by asking each other questions we had prepared in advance. That is, we prepared them without letting the other know what we were going to ask until we asked the question on stage. We also mixed in questions from the audience as we went.
My talk titled Prepare for Jakarta EE 11 was fairly well attended taking into consideration that it was scheduled in one of the last slots of the conference. I gave an overview of what to expect from all the updated specifications in Jakarta EE 11. A little extra attention was given to Jakarta Data since this is the only new specification in this release, and there is already a working implementation out there to use in a demo. Check out the slides from the talk on SpeakerDeck.
And, no EclipsCon day without the morning run. This time, Emily, Gesine, and I had a very pleasant run in almost summer-like temperatures, or at least that is how it felt since it was about 10 degrees warmer than the previous days.
We had the Jakarta EE Office Hours on the second day of EclipseCon 2023. The concept of office hours is to let attendees ask questions directly to the Eclipse Foundation staff involved in a particular area during scheduled slots. Since it is during sessions, it wasn’t exactly hectic. I had more conversations about Jakarta EE during the regular hallway track. But it is a great concept, so we will likely repeat it next year.
The Eclipse Foundation Architecture Council had a face-to-face meeting. The topic this year was the generation of SBOMs. An outcome of this discussion was that I have now created a pull request to add SBOM-generation in the parent pom.xml for all the Jakarta EE specifications and EE4J implementation projects. This means that the upcoming Jakarta EE 11 release will be delivering SBOMs for the released artifacts.,
In the evening, we had the Committer Recognition Reception, where the committers to the Eclipse Foundation projects were celebrated and could receive their committer gift. This year, it is a nice pocket knife. Luckily, there was an option to get it sent home by mail since knives and airport security usually don’t mix well…
Six early risers joined for the EclipseCon Community Run on the second day. We quickly split into two groups, hence two photos. It was a pretty cold morning, so the Jakarta EE branded buffs (neckwarmers) came in handy.
On the first day of EclipseCon 2023, Tanja and I had a three-hour Jakarta EE Workshop. Since this was the very first time we did this workshop, we were a little unsure of it would go. It turned out to go very well, even if the material was a little too extensive. Most participants were able to complete about half of the tasks during the three hours. But since it is a self-paced workshop, they will be able to complete it at any time later.
The rest of the conference day was mostly filled by the hallway track for my part. It is the best way to engage with new and old friends in the community.
#runWithJakartaEE is everywhere, and at EclipseCon there is an opportunity to run every morning. The informal Emily challenge is to join the run every day of the conference. Usually, Emily is the only one able to complete the challenge and wins it every year. Hence the name. On day two of EclipseCon 2023, Emily and I were joined by Gesine and Gaël.
With 100 registered participants, the Community Day for Java was a great success. The program was set up with alternating talks in German and English, as well as alternating topics which forced the participants to switch rooms between each session. This strategy laid the ground for a very busy hallway track.
The day ended with a Meet and Greet reception for all the participants and speakers from all the community days. Talking to the participants from the other working groups in an informal setting is excellent for the cross-pollination of experiences and ideas across these communities.
Between the sessions, the hallway track (and the occasional pool track), the receptions, and travels, there is also the ongoing work with Jakarta EE 11. The Platform calls are held as usual on Tuesdays at 11:00 a.m. ET. Join these calls to join the discussion!
JakartaOne Livestream 2023 is coming up on December 5, 2023. We have a great show planned around the celebration of the 5-year anniversary of Jakarta EE. Register now to block the date in your calendars!
If you are at EclipseCon this week, join us Wednesday morning for a refreshing start to the conference day. Gesine will guide us on a 3K, 5K, or 8K Morning Run around Ludwigsburg.
Join us in the Nestor Hotel Lobby on Wednesday, October 18 at 06:30.
