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

What a week for the Java community! Java SE 19 on Tuesday and Jakarta EE 10 on Thursday!

There are already several options available for Java SE 19. For those of you waiting for Eclipse Temurin, I can assure you that is on the way. Check the build status to be the first to know when you can get it.

The other thing happening this week, besides the release of Java SE 19, was the release of the long-anticipated Jakarta EE 10.

In the announcement The Eclipse Foundation’s Jakarta EE Working Group Releases Jakarta EE 10 to Usher in the Era of Cloud Native Java, you can among other things read quotes from 10 of the Jakarta EE Working Group members. You can also check out my Jakarta EE 10 post for some pointers on where to get started with Jakarta EE 10.

Next week, I’ll be in Chicago for JCONF.DEV, or DEEP.DISH.JAVA. if you like. My talk titled Jakarta EE 10 – Simplicity for Modern and Lightweight Cloud Applications is scheduled for Wednesday, September 28 at 10:00. I’m bringing T-shirts, stickers, and other Jakarta EE 10 swag. Don’t be shy, come and say hi!

Jakarta EE 10

The Jakarta EE 10 Release is now officially out!

This release contains updates to most of the specifications. We have also made an effort to highlight changes in all specifications on the individual specification pages. Note that the features, deprecations, etc. listed there are some highlights. For a complete list, refer to the changelogs of the specification documents.

Some of you may have noticed that the artifacts have been available in Maven Central since last week, but here they are again.

Jakarta EE 10 Platform

<dependency>
  <groupId>jakarta.platform</groupId>
  <artifactId>jakarta.jakartaee-api</artifactId>
  <version>10.0.0</version>
  <scope>provided</scope>
</dependency>

Jakarta EE 10 Web Profile

<dependency>
  <groupId>jakarta.platform</groupId>
  <artifactId>jakarta.jakartaee-web-api</artifactId>
  <version>10.0.0</version>
  <scope>provided</scope>
</dependency>

Jakarta EE 10 Core Profile

<dependency>
  <groupId>jakarta.platform</groupId>
  <artifactId>jakarta.jakartaee-core-api</artifactId>
  <version>10.0.0</version>
  <scope>provided</scope>
</dependency>

As you can see, the scope in the maven dependency definitions above is set to provided. This is the beauty of Jakarta EE. You don’t need to clutter your application’s pom.xml with lots of dependencies. They are provided for you by the runtime of your choosing. Check out the compatible runtimes already available that implements Jakarta EE 10 on the Jakarta EE Compatible Products page. New products are added to the list continuously, so make sure you revisit the page once in a while to check out the various options. Jakarta EE is all about flexibility!

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.

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

The release review for Jakarta EE 10 Platform and Jakarta EE 10 Web Profile was completed this Tuesday successfully. The official launch date is set for September 22, 2022. The artifacts are available in Maven Central, so you can go ahead and start using them already.

Jakarta EE 10 Platform

<dependency>
  <groupId>jakarta.platform</groupId>
  <artifactId>jakarta.jakartaee-api</artifactId>
  <version>10.0.0</version>
</dependency>

Jakarta EE 10 Web Profile

<dependency>
  <groupId>jakarta.platform</groupId>
  <artifactId>jakarta.jakartaee-web-api</artifactId>
  <version>10.0.0</version>
</dependency>

Jakarta EE 10 Core Profile

<dependency>
  <groupId>jakarta.platform</groupId>
  <artifactId>jakarta.jakartaee-core-api</artifactId>
  <version>10.0.0</version>
</dependency>

There are already several compatible implementations ready. The following were used for ratification of the specifications:

In addition to these, several additional certification requests have been filed (at the time of writing):

This is incredibly impressive given the number of updates, changes, and features delivered in Jakarta EE 10. It usually takes a little longer for other compatible implementations than the ones used for ratification to be ready. Great work by a vibrant community!

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

The approvals of the Jakarta EE 10 Platform and Jakarta EE 10 Web Profile are just a couple of days out. The ballots are closing on Tuesday, September 13. Allow for a couple of days until all the artifacts are available in Maven Central and elsewhere.

With Jakarta EE 10 (almost) out the door, the Jakarta EE Platform project starts to look ahead to what’s next. In the upcoming calls, there will be an agenda item for defining top objectives for the next version of Jakarta EE. Follow this thread started by Steve Millidge on the Jakarta EE Platform mailing list where the discussion already has started.

Last week, I visited Oslo and JavaZone 2022. Read my write-up from the conference to see what you missed out on if you weren’t there.

The Viking Duke that is handed out by JavaBin, the organizers of JavaZone, is one of my favorite Dukes. You can never have too many Dukes, and adding a Duke in a blog post is always a good thing.

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!

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

We’re finally there! Jakarta EE 10 is on the ballot for release review. The Jakarta EE 10 Platform and Web Profile specifications reviews will close on September 13, 2022. Core Profile passed its release review earlier in August.

It’s September, and conferences start up again after summer. First up is JavaZone in Oslo. I look forward to returning to Oslo Spektrum to present Jakarta EE 10 and catch up with the amazing Java community.

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

The conference gets a head start with Jakarta EE Community Day On Monday, October 23. I will be there, and hope to see as many of you as possible! The program is pretty much ready. Thanks to Reza Rahman for putting it together!

Not migrated from Java EE 8 yet? Luckily, there are several options available to take care of the migration for you. Check out Auto-migration of apps from Java EE 8 to Jakarta EE 9 using Windup and Openrewrite to see how the Windup project can help you. Thanks to Marco Rizzi for making me aware of the Windup Project!

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.

Format

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.

Theme

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.

Swag

Of course, there will be swag!

Hashtag Jakarta EE #139

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

The GlassFish project has released Eclipse GlassFish 7.0.0.M8 to address the TCK failures we have been struggling with over the summer. A Certification Compatibility Request (CCR) for Jakarta EE 10 Platform has been filed. We’re still waiting for a CCR for the Jakarta EE 10 Web Profile until we are ready to roll. Vacations are starting to come to an end, so I expect there will be a little more activity in the coming week.

For those planning to attend JavaOne in October, I hope we can feature a couple of Jakarta EE specifications and implementations at the Hackergarten in the Community Area most likely to happen on Tuesday and Wednesday throughout the day. Please contact me if you want YOUR project to be present!

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

On Monday, October 23, there will be a Jakarta EE Community Day. More details about the program for that day will be announced shortly. I will be there, and hope to see as many of you as possible!

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

It’s still vacation time…Even so, the work with finalizing Jakarta EE 10 goes on. I was out sailing during the last platform call, but from what I can deduct from the meeting minutes, the status is pretty much the same as last week – a clean run of the Jakarta EE TCK by Eclipse GlassFish and corresponding certification requests is needed to start the release review ballots.

I read a lot when I am taking time off work. Mostly fiction, but from time to time I pick up a non-fiction book on my Kindle reader. This week, I got my hands on Helidon in Action (MEAP) by Dmitry Kornilov, Dmitry Aleksandrov, and Daniel Kec.

For those of you not familiar with MEAP, it means that you get access to the chapters as they are written. At this point, the three first chapters were available. It gives a brief introduction to cloud-native applications and shows how to get started with Helidon before it dives into the gory details of configuration. The authors do a great job making it a great reading experience, and I look forward to the remaining chapters as they are written.

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

On Monday, October 23, there will be a Jakarta EE Community Day. More details about the program for that day will be announced shortly. I will be there, and hope to see as many of you as possible!
