JUG Milano 2024

On Monday, I visited JUG Milano together with my colleague Rosaria Rossini. She did a short talk about soft and hard skills needed for Open Source titled Java & Skills: a research activities in research@eclipse. After that, I did a talk titled Jakarta EE Meets AI where I show different ways to integrate with AI in Jakarta EE applications.

JUG Torino has frequent meetings and they are all streamed live on their YouTube channel. There were comments and questions both from those present as well as from the online viewers.

Before the event, I went for a run in the city and also had some opportunity to do a little sightseeing. After the event we went out for a delicious dinner where I got to experience the traditional food for the Lombardi region. Let me just say this, I did not go to bed hungry 🙂

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

I am in the middle of a trip across Europe that started at DevCon in in Bucharest, Rumania and continued to SFSCon in Bolzano, Italy. Right now, I am on my way to Milan and Turin to talk at the Java User Groups there. Check out the agenda for JUG Milano on Monday and JUG Torino on Tuesday. Rosaria from Research at Eclipse will join me at both these events and do an opening talk titled Java & Skills: a research activities in research@eclipse.

Jakarta EE 11 Core Profile is just about ready for release review. Everything is ready and all artefacts are staged or published according to the Jakarta EE Specification Process (JESP).

The Jakarta EE TCT Project is working heroically to finalize the TCK so we will be able to have the release reviews for Jakarta EE 11 Platform and Jakarta EE 11 Web Profile underway in the beginning of December. The goal is to have them completed, or at least ongoing when JakartaOne Livestream is happening on December 3, 2024.

I’ll end here with some pictures from the last couple of days. Until next week…

SFSCON 2024

This was the 24th edition of the South Tyrol Free Software Conference (SFSCON) in Bolzano. I is a free event that attracts visitors mostly from Northern Italy, Austria and Switzerland. This year, there were about 1000 registered attendees.

All the sessions at the conference are 15-minute long lighting talks happening simultaneously in four session rooms. This means that there are lots of sessions during the day. In addition to my talk, I also presented Carmen’s talk since she wasn’t able to make it to the conference. First, I presented A Journey of Contribution and Collaboration in Open Source. This is a talk I have done a number of times before, but usually as a 30- or 45-minute session, but it also fits as a fast-paced 15-minute lightning talk.

Directly after my talk, Tanja presented Jakarta EE: Why and how to get involved in Open Source Software? Since Juan had his talk Enabling global interoperability among smart devices is only possible through Open Source, Eclipse Foundation were already well represented before I entered the stage for my last talk about Nurturing OpenJDK Distribution in Adoptium.

SFSCon is a nice conference and the format with only lightning talks fits it well. Due to to proximity to the University of Bolzano and the free tickets, there were lots of students among the attendees.

DevCon 2024

I have been to Bucharest several times speaking at various conferences. Devcon was a new experience, even if it is organized by the same team as some of the other ones I have spoken at. It is a two day conference with multiple tracks, or stages, that vary a little between the days. The Java Stage on Day 1 was in the big room, and gathered a pretty good crowd. I would estimate that the capacity was somewhere around 200, and the room was fairly full for all the talks during the day.

My talk Why Jakarta EE Matters to Spring – and Vice Versa was one of two Jakarta EE talks among the 7 talks on the Java Stage. Edwin Derks did the other one. Adding George Adams’ Adoptium talk, Eclipse Foundation projects were very well represented on the conference.

November is almost as busy as October conference-wise, so I was only able to attend the first day before heading to the next conference. DevCon is a well-organized conference, and I can see myself coming back to speak at it later as well.

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

I had six days at home in October. November will give me thirteen days at home, and no long-haul flights planned. But there will still be quite a bit of traveling around Europe. On the first trip, I will start with DevCon in Bucharest, followed by SFSCon in Bolzano, and top it off with JUG Milano and JUG Torino.

The week after the Italian tour, I will speak at the JUGs in Prague and Brno, which will be my first time visiting Czechia. I will then go to Portugal to speak at my final in-person conference of 2024 at Porto Tech Hub.

The Jakarta EE 11 Core Profile API is ready and staged in the Jakarta EE Staging Repository. The specification document is ready, and there are two compatible implementations that have filed CCRs (Compatible Certification Requests). This means that as soon as the i’s have been dotted and t’s have been crossed, Jakarta EE 11 Core Profile will start its release review.

For the Jakarta EE 11 Platform and Jakarta EE 11 Web Profile specifications, the plan is to have the release sometime around JakartaOne Livestream on December 3.

The elections for the JCP Executive Committee will start on November 5, 2024. If you are a member of the JCP, you are eligible to vote. Please cast your vote between November 5 and November 18, and it would be extremely appreciated if yo chose to cast your vote for Eclipse Foundation. Remember that A Vote for Eclipse Foundation is a Vote for Open Source.

JJUG CCC 2024 Fall

It’s been five years since I last was in Tokyo, so it was about time to be back. Last time, I was there for the JCP EE Face-to-Face meeting as well as JJUG CCC 2019 Spring where I presented the Jakarta MVC specification. This time, at JJUG CCC 2024 Fall (I still haven’t figured out what the CCC stands for, but I am sure someone will educate me…), I gave an overview of Jakarta EE 11. I also added a demo of how to easily integrate AI in a Jakarta EE application using Langchain4j and CDI.

Even 30 million inhabitants, you can still find som quiet places in Tokyo. I had a wonderful morning run in the area around my hotel through small alleys, along rivers and in parks. Tokyo is really a collection of cities and villages all connected together with in impressive network of trains, subways, metros, and buses.

I was only on ground in a little more than 48 hours, but still got to experience a lot of the city. There is something going on all the time. And totally safe. you can (if you want) leave your mobile phone outside on a café table in a crowded area and it will still be there when you come back out after having purchased coffee inside. I don’t know any other major city anywhere in the world you would be able to do that.

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

Open Community for Java 2024 has just ended, and I am now in Tokyo to speak at JJUG CCC 2024 Fall. This will be my last conference of a pretty busy October which included travels to four different continents: Africa, North America(2), Europe, and Asia.

Some great news! I am happy to announce that IBM has filed a Compatibility Certification Request (CCR) for Jakarta EE 11 Core Profile with Open Liberty, 24.0.0.11-beta. This means that we have an implementation that implements the specification and passes the TCK so we will be able to release Jakarta EE 11 Core Profile. Red Hat is also just around the corner with a release of WildFly that passes the Core Profile TCK as well.

JakartaOne Livestream 2024 is coming up on December 3, 2024. Now that Open Community for Java is over, we can focus fully on this. The program and speaker lineup is almost ready and will be published shortly. We can look forward to a full day of amazing content from top-class speakers this year as well.

As always, we have a competition to tickle your creative side in the weeks prior to the conference. This year’s task is to use elements from the nature and create the Jakarta EE logo. In order to enter the competition, you must showcase your creation on social media and make sure you mention the Jakarta EE, or JakartaOne Livestream handles when you do that.

Open Community for Java 2024

Open Community for Java 2024 was a part of Open Community Experience (OCX), the revamped EclipseCon. EclipseCon has been going on with the same format for years, and it was in need of a brush-up. This was definitely achieved with OCX. The conference venue was fantastic and the recurring feedback was that it felt like a younger edition of EclipseCon. It don’t think that was because of the attendees as there were at least as much grey hair as usual, but more a result of the hipper vibe of the venue. The food options were excellent, and there was always access to water, soft drinks, tea, coffee, and a selection of snacks.

Since EclipseCon never really was a Java conference directed at the larger Java community (don’t get me wrong, there has always been a lot of Java content at EclipseCon, but mostly related to the various Eclipse Foundation projects, the IDE in particular), it was a bit hard to create awareness of Open Community for Java, The number of attendee could definitely have been higher, but all the talks got a decent number of attendees at least. Those that showed up had an excellent selection of high-quality talks to chose from. For those not able to attend, the talks will be available on the Eclipse Foundation YouTube channel shortly.

I did my talk Why Spring Matters to Jakarta EE – And Vice Versa on the first day of the conference. It is a good talk, if I should be so “unscandinavian” and say so. It gives a good overview of Jakarta EE and shows how the specifications overlap with Spring.

Never a conference without a morning run at least one of the days. This year, I got up at 6:30 and went for a run two of the three conference days. On Wednesday, I was joined by Daniel (I think he was motivated by the cool Jakarta EE running shirt), and on Thursday Gesine came along. This year, we had Jakarta EE branded running socks as one of the giveaways. I may have some of them to bring to future conferences if they manage to ship the leftovers to me after the event

Welcome to issue number two hundred and fifty-one of Hashtag Jakarta EE!

Busy times in October. I am just back from the Java Community Process (JCP) Executive Committee (EC) meeting in Seattle, and spending the weekend at home before heading to Mainz for Open Community for Java on Monday. The meeting in Seattle was our second face-to-face meeting of 2024.

I think that it is very valuable for the community to have Eclipse Foundation on the Executive Committee as we are the only not-for-profit Open Source organization there. It is good for the balance, the community, and YOU! Make sure to use your vote, and that a vote for Eclipse Foundation in the upcoming JCP Executive Committee Elections is a vote for Open Source!

While waiting for the elections to start on November 5, check out the Payara Hackathon on Generative AI and Jakarta EE. I am one of the judges, and I look very much forward to seeing your solutions. It is an excellent way to showcase how Jakarta EE is the perfect platform for incorporating generative AI in your applications.

GlassFish now passes 84% of the tests in the refactored TCK for Jakarta EE 11. The remaining tests are mainly related to the Application Client Container. The Jakarta EE Platform Project is proposing to deprecate the Application Container in Jakarta EE 12. There are ongoing discussions about how much importance these tests should be given to Jakarta EE 11.

The Jakarta EE 11 Core Profile TCK has been staged, and both Open Liberty and WildFly are passing (or very close to passing) it. So it looks like we will be able to release Jakarta EE 11 Core Profile ahead of Jakarta EE 11 Platform and Jakarta EE 11 Web Profile.

As I mentioned above, next week is the week of Open Community for Java. The conference is a three-day conference from October 22 to 24 in Mainz, Germany. I will be there for the entire conference, so make sure to say hello if you are there!

Directly after Open Community for Java, I am going to Tokyo, Japan for JJUG CCC 2024 Fall. It is my second time at that conference, but last time I was only attending since I was in Tokyo anyway for the JCP EC meeting in 2019.

JCP EC F2F Seattle 2024

This week the Java Community Process Executive Committee had the second face-to-face meeting of 2024. This time we met in Seattle, WA hosted by Amazon.

It was a full-day meeting with a lot of topics on the agenda. The minutes will, as always, be made publicly available on the JCP EC web page. We had external speakers presenting cool stuff, such as Project Babylon, Java 23 support in IntelliJ IDEA, and Eclipse Collections. Other topics we talked about were Java in Education and how to help the Java ecosystem to increase the adoption of newer Java features. We also discussed how we can help change the perception that “Java is old“. A lot of good ideas came up, and hopefully we will see them pop up as initiatives going forward.

The day before the meeting, some of us met with a representative from the University of Washington to gain insight of how we can assist with Java in Education system. We also had a JCP-themed JUG Meetup with the Seattle Java User Group.

Before the meeting, the JCP Runners went for a morning run in Seattle led by Volker. It is a refreshing start of the day and the best way to get prepared for a full day in the meeting room.

Every year there is an election in the Executive Committee where half of the seats are up for elections. Those elected serve a two-year term. This year, Eclipse Foundation is running in the elections to keep our elected seat in the committee. Please vote for us if you are a believer of Open Source. We are the only non-for-profit Open Source Foundation among the candidates. A vote for Eclipse Foundation is a vote for Open Source.
