Hashtag Jakarta EE #166

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

After a fairly busy start to 2023 with regard to conferences and travel, I am now taking some take off for vacation. And what better thing to do on your vacation than travel some more? Since I have switched bits and bytes with sun and surf, I will keep this Hashtag fairly short.

The Jakarta EE hackathon organized by Payara is going on. While I am on vacation, the participants are coding to win up to £3000. As soon as I am home, I will start the process of judging the work since I am one of the judges. I look very much forward to seeing what the participants are able to come up with.

The Monthly Jakarta EE Platform Architecture call is coming up next week. Make sure to join this call to make your voice heard in the planning for Jakarta EE 11.

The call is scheduled for 11:00 AM ET on February 7, 2023. Check the public calendar for details on how to join.

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

I am writing this post while traveling home from ConFoo 2023. You can read all about it here.

While I have been traveling, the work with Jakarta EE 11 goes on. The platform calls happen every Tuesday at 11:00 AM ET, and this is the place to be to get first-hand information about what’s going on. If you’re unable to attend, do check out the minutes.

One of the tasks the Jakarta EE Platform project is currently working on is gathering input from the various Jakarta specification projects to get an overview of their plans. The result of this work will feed into the release plan for Jakarta EE 11.

I also want to recap last week with a picture from the DEVIES Award ceremony at DeveloperWeek where I received the award for Jakarta EE 10 on behalf of Jakarta EE.

ConFoo 2023

My third time speaking at ConFoo was as pleasant as the previous two occasions. The three-day conference is packed with great content from a superb speaker lineup. The venue is perfectly scaled for the 720 attendees. And the food…OMG… the three-course lunches remind you that the conference is in Montreal!

Talking about Montreal. It can be cold in February. But even so, the hotel has an outdoor heated pool, hot tub, and sauna. So even if it is below -20 degrees celsius, you can still enjoy an outdoor swim when the sessions are over.

I had two talks at ConFoo 2023. The first one was Jakarta EE 10 – Simplicity for Modern and Lightweight Cloud. The room was full, and I got great feedback from the attendees.

My second talk was a non-technical one titled How to Be a Responsible Open Source Citizen. This is an inspirational talk aimed at getting more people to invest in and contribute to open source projects. This one also received great feedback, and I had some really good conversations afterward.

I would also like to thank SpeakerDeck for extending my upload quota so I am able to publish my slide decks there again. Since I reached the limit a couple of months ago, I have been forced to use another service for a while. But now I am back at SpeakerDeck. By the way, they didn’t ask me to write this or anything else in return for extending the quota…

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

I am right now on my way home after DeveloperWeek 2023. You can read about it in my blog post about the event. But there is no rest for the brave. Next week, I will be at ConFoo 2023 in Montreal where I have two talks scheduled.

Planning for Jakarta EE 11 continues in the Jakarta EE Platform Project. Currently, feedback is being requested from the various individual component specifications. Join the weekly Jakarta EE Platform project call if you want to be a part of the planning for Jakarta EE 11.

At the beginning of March, there will be a Jakarta EE hackathon organized by Payara where you can win up to £3000. I am going to be one of the judges, and I look very much forward to seeing what the participants are able to come up with.

Also, remember to sign up for Devnexus 2023, where there will be a dedicated track with Jakarta EE content.

DeveloperWeek 2023

I have visited San Francisco multiple times before, but this is the first time I have been to Oakland which is just across San Francisco Bay. The city, a short ferry ride from its more famous neighbor, has its charm and is definitely worth a visit if you’re in the area. It is also my first time speaking at DeveloperWeek at the Oakland Convention Center.

My talk titled Jakarta EE for Spring Developers went well. All the demos worked as expected, which is a good thing since the better part of the talk consisted of live demos. The talk was scheduled as the first talk on the first day of the conference, the so-called workshop day, so the attendance was a little lower than expected. But the attendees seemed happy and I got comments that it was very relevant and helpful for them as they were just about to start their migration from Spring Boot 2 to Spring Boot 3.

Another highlight of my DeveloperWeek 2023 experience was receiving the 2023 DEVIES Award for Jakarta EE 10 in the Programming Languages & Frameworks category. The award trophy was handed out during the DEVIES Award ceremony on the first day of the conference.

Jakarta EE Compatible Explained

You have probably heard the term Compatible being used in the context of Jakarta EE What does it actually mean? And what is the difference between a Jakarta EE Compatible Product and a Jakarta EE Compatible Implementation? Before we dive into explaining those terms, let’s first look at the parts a specification is made up of.

The Specification Document describes the specification in textual form. Some specifications may not have a physical document but have everything described in the JavaDoc of the API component.

The API, or Application Programming Interface, is not considered a normative artifact. That means that an implementation can reproduce the API as long as the signature of the API is identical

The Technology Compatibility Kit (TCK) defines how to test that an implementation fulfills all the requirements in order to implement the specification.

At least one Open Source(*) implementation that passes the TCK is required in order for a specification to be made final.

(*) The approved Open Source licenses for ratifying compatible implementations are EPL-2.0, BSD-3-Clause, and Apache-2.0

Compatible Implementation

An implementation of a Jakarta specification is considered to be a Compatible Implementation when it can demonstrate that it fulfills all the requirements of the Technology Compatibility Kit (TCK) for that particular specification. For example, Hibernate Validator 7.0 and Hibernate Validator 8.0 are both compatible implementations of Jakarta Bean Validation 3.0. Hibernate Validator 7.0 were used as ratifying compatible implementation when Jakarta Bean Validation 3.0 was released and is therefore listed on the Jakarta Bean Validation 3.0 specification page.

Compatible Product

A Compatible Product is a Compatible Implementation of the Jakarta EE Platform, Jakarta EE Web Profile, or Jakarta EE Core Profile. In addition to fulfilling the requirements of the Jakarta EE Platform, Jakarta EE Web Profile, or Jakarta EE Core Profile TCKs, the implementor must participate in the Jakarta EE Compatibility Program to be listed on the Jakarta EE Compatible Products page.

The Jakarta EE compatible logo can only be used by those that have implemented a Jakarta EE Compatible Product as well as fulfill the requirements of the Jakarta EE Compatibility Program.

Hashtag Jakarta EE #163

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

Tuesday this week, we had the first Monthly Jakarta EE Platform Architecture call of 2023. Don’t worry if you missed it. You can check out the minutes or watch the recording on YouTube. The minutes from all Jakarta EE Platform calls are always captured on the Jakarta EE Platform Project’s website.

The conference season goes on. Last week, I was in Stockholm for Jfokus. You can read about my trip in my blog post from the trip. Next week, I will be in Oakland, California for DeveloperWeek where I will present a brand new talk about how to handle the javax.* to jakarta.* namespace switch in Spring applications.

Totally unrelated, but sort of ties into the Community Morning Runs I like to do at conferences… This weekend I ran Tjörnarparen Trail Ultra 50K and survived. Didn’t see any wild boars even if they’re known for roaming the woods in the area.

Back on topic…Remember to sign up for Devnexus. The conference will go on at the Georgia World Congress Center in Atlanta from April 4 to April 6. This year’s conference will have a dedicated Jakarta EE track. Use the code SEEMESPEAK to get a nice discount. And of course, I will arrange a morning run there as well, so make sure you bring your running shoes.

Jfokus 2023

Jfokus is one of my absolute favorite conferences. This year’s edition was no exception. The organization is excellent, you can tell that they’ve done this before. This was the 17th edition of Jfokus since it started back in 2007.

On Wednesday morning, we continued the tradition that started last year with a Jfokus Morning Run. Which made this year the second annual morning run at Jfokus.

We were 17 runners that met at 07:15 on Wednesday morning for a 5K run, and as far as I know all 17 returned and were able to attend the conference. It is truly an excellent way to start a conference day.

I had a Quickie-talk about responsible Open Source at Jfokus this year. A Quickie talk at Jfokus is a 15-minute talk, so it is pretty fast-paced. A fun experience. And I hope the participants found it interesting as well. The room was almost full, so the topic seems interesting at least.

Hashtag Jakarta EE #162

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

We have reached February, and are now a month into the first quarter of 2023. The Jakarta EE Platform Project is in the midst of putting together a release plan for Jakarta EE 11.

The goal is to propose a reliable plan for delivering Jakarta EE in Q1 2024 as formulated in the high-level guidelines for Jakarta EE 11 formulated by the Jakarta EE Working Group Steering Committee.

One of the release planning activities is gathering input from all Jakarta EE specification projects. There will be a short survey for these projects to provide input to the Jakarta EE Platform project that will be sent out early next week. One of the questions in this survey is about release plans for the individual component specifications.

With this in mind, it was extremely great to see the release plans for Jakarta Expression Language 6.0 and Jakarta Server Pages 4.0 communicated last week. Great work! Hope to see more of these shortly.

The Monthly Jakarta EE Platform Architecture call is coming up next week with an update on Project Loom in the context of Jakarta EE by Alan Bateman and Ron Pressler from the JDK Team at Oracle.

The call is scheduled for 11:00 AM ET on February 7, 2023. Check the public calendar for details on how to join.

Another thing that happened last week was that Jakarta EE 10 was awarded the 2023 DEVIES Award for best innovation in Programming Languages & Frameworks. Congratulations to everyone involved!
