US South JUG Tour 2024

Next week, I am going overseas on tour with Jakarta EE. I will visit a handful of Java User Groups in the South of the USA. The tour schedule looks like this:

September 9 – 6:00 PM – TriJUG – Durham, NC – Details and registration
September 10 – 6:00 PM – JaxJUG – Jacksonville, FL – Details and registration
September 11 – 6:30 PM – JavaMUG – Dallas, TX – Details and registration
September 12 – 6:30 PM – Gateway JUG – St. Louis, MO – Details and registration

If you are in or near these cities, I encourage you to attend these free events and support the local Java community. I certainly hope the talk is enough to convince you to attend. If the topic does not appeal to you, that in itself is no reason to stay at home as the most giving part of these events is the opportunity to socialize with fellow Java developers in the local community.

When the JUG tour is over, I am going further south over the weekend to Puerto Vallarta in Mexico to attend the Jalapeño Unconference. Unconferences are another opportunity to meet and discuss topics at heart with fellow community members. Take a look at The JUnconference Alliance to find an unconference near you. If there aren’t any nearby, start one yourself, or pack the bags and go to one. You won’t regret it!

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

Last week was very productive for the TCK Project. Different options for how to be able to deliver Jakarta EE 11 was discussed. Among those a hybrid approach to require parts of the TCK to be run the old way, and parts of it with the newer technology stack. The current plan of refactoring the entire Jakarta EE 11 TCK still stands.

The Jakarta EE Platform project meets weekly, and have started the initial talks around how to form the Jakarta EE 12 release. Jared Anderson (IBM), will join Ed Burns (Microsoft) as the release coordinator of this release. Join the platform call and the Jakarta EE Platform project mailing list to be a part of these discussions.

The following week, I will be preparing the upcoming Jakarta EE US South JUG Tour with talks at the Java User Groups in Durham, Jacksonville, Dallas, and St. Louis. I look forward to meeting the Java communities in these cities. I will post more information about the tour in the upcoming week.

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

Even if progress is being made with refactoring the Jakarta EE Platform TCK, the effort is in desperate need of more resources to complete the work in a timely matter. If you have any experience with TCK work, your help would be greatly appreciated!

An Interest Group called Jakarta EE Future Directions has been initiated. You can join it by signing up on the group mailing list. The purpose of the group is to gather ideas and input from the industry and community for how to evolve Jakarta EE. Ideas and suggestions coming out of this group will be brought forward to the relevant Jakarta EE project(s) for potential inclusion in future releases.

I am on my way back from the LAOUC Community Tour 2024 stop in Paraguay. This was a soft kickoff for my fall conference season that really starts in September and will go on throughout December. Check out the list of appearances (updated continuously).

LAOUC Community Tour 2024

When I got the opportunity to be a part of the LAOUC Community Tour 2024 with two talks in Paraguay, I immediately accepted. This was my first visit to the country. It is not the first destination that comes to mind, and I had to google what the name of the Capital is (Asuncion).

There are two official languages in Paraguay, Spanish and Guaraní. Since I don’t speak either, if you don’t count my limited Spanish obtained from Duo Lingo, and English is only understood to a certain degree, the organisers set up the English speaking speakers with a translator. Having someone repeating your sentences in a different language during the presentation breaks up the rhythm and takes a while getting used to. Especially when you are told about it a couple of minutes before the talk starts.

The first talk was my migration talk From Spring Boot 2 to Spring Boot 3 with Java 22 and Jakarta EE. I was able to cut som content on the fly since the translation eats up a good percentage of the time.

For my second talk, I was prepared for the translation and reduced the content in advance. This talk was about how to Boost Performance and Developer Productivity with Jakarta EE 11.

The event was the last stop on the LAOUC Community Tour 2024 and was very well organised by the Paraguay Oracle User Group (OUGPY). Here are some photos of the speakers, attendees, and a display of Jakarta EE swag.

I had a great couple of days in Paraguay, and would not hesitate to go back on a later occasion. Of course, I had to pick up som Yerba Mate to bring home.

Another short summer update. The update for Jakarta EE 11 is about the same as last week. We are still waiting for an estimated delivery date from the Jakarta EE TCK Project. Follow the GitHub Project board for the progress.

This week, I will join the LAOUC Community Tour 2024 where I have two Jakarta EE talks scheduled. Even if it is only a couple of weeks, it feels like it has been forever since I last was traveling. It will be good to be on the road again to meet our amazing community.

Eclipse Loves Java by Hendrik Ebbers

Developers can choose from multiple OpenJDK distributions and create applications or microservices using frameworks such as Spring Boot, Micronaut, or Quarkus. Despite this diversity, shared standards and specifications remain, managed by the Eclipse Foundation’s working groups. In this session, Hendrik Ebbers, CEO at Open Elements, will explore the Eclipse working groups and projects driving Java forward, helping developers and companies create innovative open source solutions. Learn more. 

Why Spring Matters to Jakarta EE – and Vice Versa by Ivar Grimstad

Jakarta EE 9’s namespace change from javax to jakarta has significant implications for the entire Java ecosystem, including Spring. This session by Ivar Grimstad from the Eclipse Foundation will explain why Spring developers should care about Jakarta EE updates and how Jakarta EE can benefit from Spring’s innovations. Learn how Spring and Jakarta EE influence each other and how they can collaboratively advance Java technologies. This talk will be particularly insightful for developers looking to leverage both Jakarta EE specifications and Spring Framework advancements. Learn more.

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

Summer is still around, and the refactoring work of the Jakarta EE Platform TCK moves on. According to the Jakarta EE TCK Project, they will soon be able to empirically derive a date for when the work can be done and we will have a release date for Jakarta EE 11.

If you plan to join us at Open Community for Java in October, make sure to register before September 23 to get the discounted price. Check out the agenda. Adjust the filter to “OC for Java” to see the talks at Open Community for Java (OC is not Orange County in this context, but Open Community…and much better than the TV show…).

My next endeavor will be in a couple of weeks when I will join this crew for the last leg of the LAOUC Community Tour 2024 where I will have two Jakarta EE talks.

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

The work with Jakarta EE 11 continued while I was at JConf Dominicana, JCrete, and a short vacation thereafter. Since a couple of specification projects have published service releases to fix minor issues in their API artifacts or Java Doc, a release candidate of the Jakarta EE 11 APIs incorporating these updates will be produced shortly. There will most likely be a release candidate of the specification documents as well.

The next speaking appearance for me will be the LAOUC Community Tour 2024 where I have two talks included in the agenda for Paraguay. It’s been a while since I have had three consecutive weeks at home with no travels planned.

The agenda for Open Community for Java has been published.
A tip is that if you only want to see the talks of Open Community for Java, click on the orange “Filters” button on the left side and select “OC for Java” (Yes, I know, we all hate these acronyms that are created for no apparent reason other than text length limitations. Just do as I do: ignore and hum “Open Community for Java” in your head when you see it…).

JCrete 2024

Attending JCrete has become a tradition for me. It is high up there among my favorite events and probably my favorite location. Whenever possible, I take some time off before or after the conference to explore the Island of Crete.

Every day at JCrete starts with a morning run. You have to be up early for this as it gets very hot very quickly and the hills above the OAC are pretty steep.

But JCrete is about so much more than the running, the location, the food….It’s all about the people! And the conversations. It is not often you get to spend a week in the company of such a group of dignitaries of the Java community in such relaxed circumstances. If you ever get the chance to attend JCrete, just do it!

Since JCrete is an unconference, there are no scheduled talks. The topics for the sessions are presented and voted on every morning and the schedule materializes from that. An interesting observation is that the topics on the first and second days are usually very technical, low-level JVM stuff. Whereas later in the week, the softer topics of remote working, burnout, traveling, and coping with various work situations are more common.

After JCrete, there is no better place to be than on a beach with coffee in the making and delicious Cretan thyme honey on Greek yogurt.

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

I am taking a week off, so this will be a rather short update. Last week was the week of JCrete 2024. I will publish a blog post about this year’s edition as soon as I am home from vacation.

The Jakarta EE Platform project continues the work toward finalizing Jakarta EE 11. The refactoring of the TCK shows promising results. Hopefully, we will be able to announce a release date shortly. Check in to the weekly Jakarta EE Platform call that happens every Tuesday at 11:00 AM Eastern (Daylight Savings) Time.

Remember to sign up for Open Community for Java. The conference will be in Mainz, Germany from October 22 to October 24. I will be there, and so should you!
