EclipseCon 2022

For EclipseCon 2022, we were back in Ludwigsburg again. Since the two previous editions of EclipseCon were virtual, this was the first time since 2019.

On Monday before the main conference, we had the Jakarta EE Community Day. The agenda featured a lot of interesting talks and discussion topics. Thanks to Reza Rahman for putting it together!

The program of EclipseCon 2022 contained lots of Jakarta EE-related content. The Jakarta EE stand was co-located with iJUG, and they did a great job handing out Jakarta EE branded luggage tags, card holders, hoodies, and stickers while answering questions from the attendees.

My talk titled Jakarta EE 10 – Simplicity for Modern and Lightweight Cloud Applications gathered a decent crowd. Check out the slides here.

As Justin points out, Java runs anywhere. And so does Emily. So this year we launched the Emily Challenge, which was to run every morning while at EclipseCon. I really enjoy these morning runs as a way to kickstart the conference days. We also had the annual Jakarta EE Community Run on Wednesday were six runners showed up.

JavaOne 2022

JavaOne is BACK! Even if the 2022 edition was a bit smaller than we are used to for JavaOne, it still had the good old JavaOne community feeling. It didn’t really matter that it had moved from San Francisco to Las Vegas. The Caesar’s Forum is an excellent venue for JavaOne! And it was only a short walk over to the Venetian Expo for those that wanted to pay Oracle Cloud World a visit.

The only one missing the main character of them all. Somehow, Duke didn’t make the move from San Francisco to Las Vegas. My guess is that he is roaming the streets around the Hilton looking for Duke’s Café. If you see him, please point him in the direction of Las Vegas, so he can join next year’s JavaOne.

Before the conference, a small group of us went for a trip to Red Rock Canyon. You can read all about it in Jakarta EE Social Run – Red Rock Canyon.

There was a lot of Jakarta EE content at JavaOne 2022, as indicated in my post Jakarta EE at JavaOne 2022.

One of my favorite moments was working on the Eclipse Starter for Jakarta EE at the Hackergarten on Wednesday morning together with Josh Juneau and Ivo Woltring. We made great progress, and you will soon be able to generate Jakarta EE projects in the easiest way possible. Stay tuned for more announcements regarding this.

The JCP party is one of the highlights of every JavaOne. No exception this time. Heather knows how to throw a party! Catching up with old and new friends while enjoying great food, drinks, and the Nullpointers band.

Hope to see as many of you as possible at JavaOne in September next year!

Jakarta EE Social Run – Red Rock Canyon

Early Sunday morning, a small group of developers got in a car and headed for the Red Rock Canyon. After navigating through the mazes of casinos on the Strip, they made it there.

Among the five, there were three runners, Mattias, Rustam, and Ivar (myself if you were in doubt). The rest of the group was Gerrit and Mads who took care of the photography. They also took care of the car keys, so at least they would make it to JavaOne if the rest of us got lost in the desert…

After a 3.2km warmup run, we decided to go for Turtlehead Peak. 3.7km and an elevation gain of 800m should be within our capacity.

The three of us set off for the summit.

Shortly after, we were down to two. And after a while the two in front also got separated. So we ended up being three hikers, as it turned out to be a little to steep to run uphill, finding our own pace to reach the top.

All three of us, wearing our nice, blue Jakarta EE runner’s shirts, made it to the top and back down again.

Including the warmup run, a total of ~10km and 800m elevation.

The runners before starting, all wearing the beautiful, blue Jakarta EE runners shirts.
Selfies are essential even when running, as Mattias and Rustam demonstrate here.
To be fair, they started running shortly after the photo moment. And kept going!

Devoxx Belgium 2022

What an event Devoxx Belgium is! 3200 attendees, more than 200 speakers, and five days packed with awesome content. And, of course, the hallway track! Kinepolis in Antwerp during Devoxx is definitely the place to be if you are a Java developer interested in interacting with the best.

My talk titled Jakarta EE 10 – Simplicity for Modern and Lightweight Cloud Applications was scheduled for Thursday early afternoon. It went well, all the demos worked, and I received a lot of positive feedback after the session.

I also did a Jakarta EE BOF with Edwin on Tuesday evening. Even at this late hour, a decent crowd turned up, and we had some interesting discussions. If you’re new to conferences and want to have some informal interaction with the experts within a field, BOFs are a great place. This is exactly what they are for.

Jakarta EE at JavaOne 2022

JavaOne in Las Vegas is just a couple of weeks away. As it turns out, Jakarta EE will have a pretty good presence at the conference. My three Jakarta EE-themed sessions are:

  • Jakarta EE BOF [BOF4038]
    Tuesday, October 18 at 18:45
  • Jakarta EE 10: Simplicity for Modern and Lightweight Cloud Applications [LRN3693]
    Wednesday, October 19 at 15:45
  • The Jakarta EE Panel [LRN3679]
    Thursday, October 20 at 14:30

Make sure to check out all the other Jakarta EE sessions listed in the session catalog. A lot of great topics by great speakers!

On Wednesday, October 19 between 10:00 and 12:00, I will be in the Hackergarten with the Eclipse Starter for Jakarta EE project. Please join me there to work on the If you are unfamiliar with Open Source and/or the Eclipse Foundation, I will help you get started. This is an excellent way of kick-starting your career within open source.

If you are like me and enjoy a morning run before the conference, then you’re in good company. Please join us for the JavaOne Run (aka Duke’s Morning Run) on Wednesday, October 19 at 06:00. Chad will take us on a 4-mile (6.5km) morning run at a relaxed pace to the new Las Vegas sign and back on the North side of the Las Vegas strip. Check out the details of this, and all the other community activities in the JavaOne Update Series.


JConf Dev 2022 (aka DEEP. DISH. JAVA.) felt like a smaller version of Devnexus. It sure has the potential to grow into something more prominent once the fine citizens of Chicago discover what they missed out on in 2022. Stay tuned for 2023, and make sure to grab your ticket before it is sold out!

Besides enjoying the culinary treats of Chicago (i.e. deep dish pizza), I also had a talk titled Jakarta EE 10 – Simplicity for Modern and Lightweight Cloud Applications on the second day of the conference. You can check out the slides below.

I always try to get a morning run when I am at conferences. As does Emily, so when we’re at the same conference we usually go for a run together. In Chicago, we met up at 6:30 every day for a run along Lake Michigan.

JakartaOne Livestream 2022 CFP is OPEN

The Call-for-Paper for JakartaOne Livestream 2022 is now open. As in previous years, this will be a one-day virtual conference that focuses on technologies evolving around Jakarta EE. The event will happen on December 6, 2022.

The CFP will close on October 17, 2022. This year’s program committee will be doing rolling acceptance, so don’t wait until the last minute to submit. Early submissions have a better chance of getting accepted.

Submit your abstract now

You are probably all sick and tired of virtual events, and by now got the taste of what you have been missing from physical events. But, JakartaOne Livestream is one you don’t want to miss! I will actually go as far as saying if you’re speaking at one virtual event this year, it should be JakartaOne Livestream.

Previous Editions

JavaZone 2022

It is always pleasant to come back to my home country, even if I get a complete language meltdown as soon as I cross the border. Good thing Java is the common language 🙂

JavaZone draws a big crowd. 2500 developers at this year’s edition. Food is served in the exhibition hall throughout the day, so there are always a lot of people there. Definitely, a concept other conferences should consider if the facilities allow it.

My talk Jakarta EE 10 – Feature by Feature was scheduled for Thursday morning. It gathered a decent crowd despite the Awezone party going on into the late hours on Wednesday. All the Jakarta EE T-shirts, coasters, mouse pads, and screen wipes were handed out to the attendees. And stickers of course, always stickers!

JakartaOne Livestream 2022 – Save the Date

The planning for this Year’s JakartaOne Livestream is about to start. Make sure to mark December 6, 2022, in your calendars!

Program Committee

We will soon start the work of putting together a program committee that will be responsible for reaching out to speakers and selecting talks. If you are interested in participating in this work, now is an excellent time to reach out to Tanja or me so we are made aware of your interest.


JakartaOne Livestream 2022 will be virtual, that’s for sure. And it will most likely be a 12-hour show to accommodate most time zones. If you have any input regarding this, now is an excellent time to reach out to Tanja or me to tell us.


We usually choose a theme for JakartaOne Livestream. And we use this theme for a competition among the community members. The themes so far have been cake, cupcake, and pizza. It seems like there is a food theme for the themes, so I guess we should continue in that spirit this year as well. Any suggestions for what it should be? Now is an excellent time to reach out to Tanja or me to let us know.


Of course, there will be swag!
