JBCNConf 2022

JBCNConf 2022 was my last conference for the “season”. And what a conference! It is organized by the Barcelona Java User Group and has had a steady increase in the number of attendees from year to year. This year with more than 1000 participants!

Jakarta EE had a booth in the Community area of the exhibition hall that was staffed by Jadon from Payara in addition to Tanja and me. Emilemilyfhjiangy from IBM helped out as well. We had Jakarta EE branded mousepads, coasters, and screen wipes in addition to the awesome Jakarta EE stickers to hand out to those visiting us.

I presented Jakarta EE 10 – Feature by Feature on the second day of the conference where I incorporated a demo of Payara Cloud to show how easy it can be for developers to deploy Jakarta EE applications nowadays. It truly fits with the Simplified theme of Jakarta EE 10.

And of course, every conference day starts with a morning run.

EclipseCon 2022 Registration is open

The registration for EclipseCon 2022 is open. This year’s EclipseCon will take place in Ludwigsburg, Germany from October 24 to October 27.

There are some great Jakarta EE talks for you to attend! Also, remember to browse the complete program as there may be other topics that you will find interesting as well.

Here are a couple of arguments you can use if you need to convince your boss to be allowed to go to EclipseCon 2022:

  • Inspiration – get inspired by attending talks by some of the greatest speakers in the community
  • Network – meet and mingle with committers from all of the Eclipse Foundation projects
  • Learn – listen to domain experts
  • Master – participate in the hands-on-labs, or contribute to open source projects in the hackerspace
  • Discuss – use the opportunity to discuss issues from your daily work with other community members in the hallway

Welcome to issue number one hundred and thirty-three of Hashtag Jakarta EE!

GlassFish 7.0.0-M7 passes the Jakarta EE 10 Platform TCK. The issues that are left affect the TCKs for Jakarta EE 10 Web- and Core Profiles. There is light at the end of the tunnel, but it is hard to predict precisely when these issues will be resolved. The best way to stay informed is to join the platform call on Tuesdays and/or follow the mailing lists, and of course follow the Hasthag Jakarta EE blog series.

The proposal for the Jakarta Data specification has completed the community review, and it is now being prepared for creation review ballot by the Jakarta EE Specification Committee. All according to the Jakarta EE Specification Process (JESP).

The Registration for EclipseCon 2022 is now OPEN! Make sure to register in order to save you spot at the event happening in Ludwigsburg in October. There are some great Jakarta EE talks for you to attend. And, as always, a bunch of other topics as well.

And, if you are into running, I will arrange a Jakarta EE Community Morning run at least one of the days of the conference. Look out for #runWithJakartaEE on social media when we’re closer to the event.

Next up for me, if the traveling gods are still with me, is JBCNConf in Barcelona from July 18 to 20. I will present a talk titled Jakarta EE 10 – Feature by Feature, and Tanja will present Jakarta EE: Community Power and Progress.

Here’s some good news if you are a sucker for cool swag. While I was at the Eclipse Foundation All Hands meeting this week, I picked up a bunch of swag to give away at the upcoming conferences. When I checked in to my flight at Ottawa Airport, I discovered that mouse pads are heavier than they look. Solved it by taking them as hand luggage. Part of the story is that my baggage is loaded with maple syrup, so it was already quite heavy 😋

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

The program for EclipseCon 2022 has been published! The conference will be in Ludwigsburg, Germany from October 24 to October 27 later this year.

There is no fast track for Eclipse Foundation staff to speaking slots at EclipseCon. We have to submit abstracts just like anyone else aspiring to become an EclipseCon speaker. Luckily, I got two talks accepted. One of which I am listed as co-speaker.

My accepted talks are Jakarta EE 10 – Simplicity for Modern and Lightweight Cloud Applications and Jakarta EE Security – Sailing Safe in Troubled Waters (co-speaker with Werner Keil).

The status is more or less the same as I reported in Hashtag Jakarta EE #131 last week. There are three remaining issues to resolve before the release is ready. 1) CDI Language Model TCK failure in GlassFish, 2) Jakarta Concurrency 3.0 TCK contains remote Jakarta Enterprise Beans, and 3) Jakarta RESTful Web Services 3.1 TCK contains tests for Jakarta XML Binding 4.0.

The Eclipse GlassFish project is working on a fix for 1), and there are Pull Requests being discussed for 2) and 3), so there is a small possibility that the Jakarta EE Platform, Web– and Core Profile can be ready for release review ballots the upcoming week.

The Jakarta EE Platform passes the TCK, and has filed a Compatibility Certification Request for Eclipse GlassFish 7.0.

I had a great trip to DWX’22 last week, even if the travel home took a little longer than planned. A flight turned into a train ride and an extra night at a Frankfurt Airport hotel before an early morning flight back home. Now, let’s see how Tomorrow’s trip to Ottawa will be affected by striking pilots…

Developer Week ’22

This was my second time in Nürnberg for Developer Week. The last time I spoke here was in 2017, except for an online talk in 2021. If I should estimate, the conference this year was about half the size of what it used to be, which is pretty normal nowadays. With around 5-600 attendees daily, it is still a decent-sized conference.

Developer Week is mostly geared towards .NET developers, but there is a Java track as well with quite a few interesting talks. I was a co-speaker with Werner Keil on Jakarta EE Security – Sailing Safe in Troubled Waters.

Right after this talk, my talk titled Jakarta EE 10 – Feature by Feature was up. It was nice to have a full hour to present, with plenty of room for live demos. Usually, I have to cut a couple of the demos a little when the speaking slot is shorter.

Before going to the conference, I did a morning run along the old city walls of Nuremberg. Of course, wearing my Jakarta EE running shirt!

Hashtag Jakarta EE #131

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

Jakarta EE 10 isn’t quite released yet, but that doesn’t stop us from celebrating the release. Check out the recording of the Jakarta EE 10 Release Celebration if you weren’t able to join us live last Tuesday.

The release itself is imminent. There are a couple of TCK challenges that need to be sorted out and dealt with to get everything to pass. GlassFish 7 currently passes the Jakarta EE 10 Platform TCK, but there are some changes required in the Jakarta Concurrency 3.0 TCK related to Jakarta Concurrency now being a part of Jakarta EE 10 Web Profile. It was not required for the Web Profile in previous releases, and some cleanup with regards to the packaging of the test deployments has to be cleaned up. Jakarta EE 10 Core Profile has some similar issues, but this is regarding some of the tests for Jakarta RESTful Web Services 3.1 still references Jakarta XML Binding 4.0. This works well for Web Profile, where Jakarta XML Binding is required, but not for Jakarta EE Core Profile where it’s not.

So to sum up, it is very close. Just some small nits that have to be dealt with. Then we should be ready to go!

After a week at home in sunny Sweden, I am going to Nürnberg, Germany for Developer Week ’22 this week. I have two talks at this Years’s edition. First out is Jakarta EE Security – Sailing Safe in Troubled Waters, where I am co-speaking with Werner Keil. Directly after this talk, Jakarta EE 10 – Feature by Feature is up.

I will most likely go for a run in one of the parks in Nürnberg on Thursday morning. Let me know if you’re into running and want to join me. If I know you’re coming, there is a cool Jakarta EE functional T-shirt in it for you. Werner, I’ve got you covered 🙂

Devoxx Poland 2022

Devoxx Poland is a great conference! The venue is located near Kraków city center within walking distance of most hotels and restaurants. With almost 3000 participants, even the large ICE Kraków Congress Centre gets crowded. But with the warm sunny weather and ice cream served outside, that was never an issue.

My talk titled Get READY for Jakarta EE 10 was scheduled for Wednesday afternoon. Those present appreciated the talk, but with the late time slot and in one of the rooms on the top floor, it was a little sparsely populated. But it was recorded, and maybe live-streamed(?), so check it out if you weren’t able to attend!

Hashtag Jakarta EE #130

Welcome to issue number one hundred and thirty of Hashtag Jakarta EE!

This week, I was back in Kraków for Devoxx Poland. I have been to most Devoxx conferences before, but this was my first visit to Devoxx Poland. It is a great conference at the modern Kraków Congress Center close to the city’s center. I’ll provide a write-up of this conference in the coming days.

So, Jakarta EE 10? Are we there yet? Due to travel and Midsummer this week, I’m not 100% up-to-date on the status, but the last I saw, the Jakarta EE Platform, Web- and Core Profile are very close to being ready for release reviews. Hopefully, we can get them moving in the upcoming week.

Talking about the upcoming week, we will have a Jakarta EE 10 Release Celebration on Tuesday.

We will have some fantastic guests giving their views of Jakarta EE 10. Join Shabnam Mayel, Tanja Obradovic, and myself with special appearances from Adam Bien, Rudy de Busscher, and Scott Stark.

Hashtag Jakarta EE #129

Welcome to issue number one hundred and twenty-nine of Hashtag Jakarta EE!

The conference season continues. I represented Jakarta EE this week at the We Are Developers World Congress in Berlin. Next week, I am heading to Kraków and Devoxx Poland. But before that, I will be participating in Jakarta EE 10 – exploring the value of innovation in the open. This online event happens at 9:00 AM Eastern Time on Tuesday, June 21. Make sure to register now so you are sure not to miss it!

I will also remind you about the  Jakarta EE 10 Release Celebration Tech Talk we are hosting on June 28. Please sign up and join us there!

So, with all these celebrations and events around Jakarta EE 10, when can we expect the release? As I mentioned in Hashtag Jakarta EE #128 last week, one of the challenges is the requirement that the compatible implementation used to ratify the specification must pass all features, including the OPTIONAL ones.

To address this issue, the Jakarta EE Platform team decided to remove Entity Beans, both Container and Bean Managed Persistence (Jakarta Enterprise Beans 4.0, Optional Features, Chapters 3 – 7) OPTIONAL requirements for Entity Beans from the Jakarta EE 10 Platform specification. This will open up the possibility for other open-source implementations than Eclipse GlassFish to be used for ratifying the specification.

That said, Eclipse GlassFish is getting closer and closer to passing the TCK, so it is likely that it will pass the finishing line first anyway. From what I can see, the remaining task is to integrate an implementation of Jakarta Concurrency 3.0 and pass the new standalone TCK for this specification.

We Are Developers World Congress 2022

We Are Developers in Berlin is a massive event! It’s been a long time since I have been among so many people in one place. This would be considered a big crowd even by pre-pandemic standards.

My talk Get Ready for Jakarta EE 10 was scheduled as one of the first talks on the opening day of the conference. It was well attended, and those I talked with after the talk were happy and appreciated it.

We Are Developers is a polyglot event catering to a larger crowd than the usual more Java-focused events. Still, there were a lot of familiar faces. It was great to catch up with old friends and meet some new ones.

One advantage of having a conference in a big city like Berlin is that there are loads of options for what to do when not present at the venue. I spent a couple of hours in the Berlin Zoo before my flight home, and there I came across this fellow. Is it Duke in disguise? Has he lost his red nose? After a closer look, I can assure you that Duke is fine, and this is just a baby panda enjoying a nice chunk of bamboo for breakfast.
