On the fun side, I was made aware that my shoutout for the Hashtag series may be a little confusing as you can see in my conversation with Ronnie Zolverda.
I didn’t want to use #5 to indicate number 5 since Twitter would then interpret the hashtag (#) as if I were tagging the number 5. Also interesting that nobody reacted on the first 4 posts…
From this week on, I will tweet that “Hashtag Jakarta EE number X is out!” to avoid confusion in the future 🙂
So, over to the technical side. Gunnar Morling referred me to a recent article of his where he describes how to use the JDK Flight Recorder to monitor REST APIs.
We didn’t have any Jakarta Tech Talks or Update calls this week, but the work with Jakarta EE 9 proceeds as planned. The status is best followed by checking out the project board. We have now passed the deadline for individual component release plans. These are Java Activation Framework 2.0 and Jakarta Enterprise Beans 4.0. The rest will follow the release plan for the full platform.
So far, there are two proposals on the table; a joint working group or two separate working groups. While the structure of the working group(s) is important, another aspect is the technical alignment of Jakarta EE and MicroProfile. A couple of weeks ago David Belvins put forward a couple of proposals to bootstrap the discussions. A third proposal was presented by Steve Millidge where he proposes that profiles in Jakarta EE are promoted to individual brands and that MicroProfile becomes a profile of Jakarta EE. Interesting thoughts!
This weekend, I attended my first FOSDEM. This is a free event that takes place in Brussels every year. It is quite an experience with fully packed rooms and crowded corridors. Sessions are short (25 mins) and focused. Absolutely a recommendation!
This post is meant to clear up some misunderstandings that occurred during a discussion thread on the Jakarta EE Community mailing list. Some of this is a repetition of what I described in Jakarta EE 9 Shaping Up in December, but such an important topic cannot be stressed enough.
The only thing you need in order to contribute to Jakarta EE specifications is a signed ECA!
First of all, to contribute to any open source project at the Eclipse Foundation, you will need to create an account and sign the Eclipse Contributor Agreement (ECA). See below for a visualization of this process.
You can now start contributing by submitting Pull Requests to the projects you are interested in, including Jakarta EE specification projects. It doesn’t cost anything. No signatures from your employer are necessary. Just the ECA. The only thing you need in order to contribute to Jakarta EE specifications is a signed ECA!
The more you contribute, the more likely it is that you will be proposed to become a committer to the project. I will describe the zero-cost way of becoming a committer in a follow-up post to this one.
We’re on a roll here! I can’t believe it is already four weeks since I started this series!
Stay tuned for announcements about Jakarta MVC!
A little on the side of Jakarta EE, but still related is that the MVC 1.0 specification (JSR 371) is finally final! We have been working with this for a long time, and special thanks to Christian for his work in getting the release out the door! Without him, I doubt there would be a release of MVC!
So, why isn’t MVC already moved over to the Eclipse Foundation and Jakarta EE? The short answer to that is that we wanted to finish the first release under the JCP in order to have a released project to transfer. We have already transferred Krazo, the reference implementation and the plan is to start the transfer of the specification and the TCK shortly. Stay tuned for announcements about Jakarta MVC!
Jakarta EE 9 is moving forward with great progress. The status of all the work is tracked on the Jakarta EE 9 tracking board. If you are involved in one of the specifications in the Plan Review column, you are encouraged to take a look and see how you can help move these specifications forward to the In Progress column. Instructions can be found in notes at the top of the columns.
Most of this week was spent at the Eclipse Foundation office in Ottawa. It is great to have the opportunity to meet the people I work with daily in person once in a while.
On Tuesday, January 14, there was an off-week MicroProfile Hangout dedicated to the discussions around the Working Group proposals for MicroProfile. The hangout was pretty well attended with the usual suspects doing most of the talking. See the presentation and meeting minutes for more details. The session was even recorded.
Attending conferences like CodeMash that are not entirely Java-centric is a great reminder that outside our bubble, most developers haven’t heard about Jakarta EE or MicroProfile at all!
It is both challenging and rewarding to give a talk where you are not preaching to the choir. I encourage you all to do this more often. This is how we spread the message! This is how we grow our community!
In the Jakarta EE space, we started the week with an EE4J PMC meeting followed by the Jakarta EE Steering- and Specification committees. The most important agenda item discussed is the ongoing ballot for approval of the Jakarta EE 9 release plan in the Specification Committee. You can follow the ongoing ballot on the Jakarta EE Specification Committee mailing list.
At the end of last year, the Java EE Guardians completed their rebranding to become the Jakarta EE Ambassadors. I am really happy that I was able to help in the process of getting the new logo created. This is the first approved usage of the Jakarta EE brand and logo outside of the Jakarta EE Working Group. A milestone in itself!
For a while now, I have been thinking of posting more regular updates about stuff going on in the Jakarta EE community. Kind of what Josh Long does with his “This Week in Spring” series. Being a big fan of Josh and the work he is doing in the community, I am not ashamed of copying him.
The goal is weekly updates, but being realistic I leave out the cadence from the title. So welcome to the first issue of Hashtag Jakarta EE!
The year 2020 is still young and pristine, most members enjoying a well-deserved vacation after a busy 2019.
It is time for my yearly summary of conferences and community activities. In addition to numerous local meetups and online events, I had the opportunity to speak at the following major developer conferences:
Jfokus, Stockholm Devnexus, Atlanta ConFoo, Montreal JavaLand, Brühl JEEConf, Kiev QCon, São Paulo DevTalks, Bucharest Java Cloud Africa, Johannesburg J4K, Orlando Oracle CodeOne, San Francisco EclipseCon Europe, Ludwigsburg Trondheim Developer Day, Trondheim Devoxx Ukraine, Kiev Devoxx Belgium, Antwerp Devoxx Morocco, Agadir Java2Days, Sofia
The biggest change for me this year happened in October when I joined the Eclipse Foundation as the Jakarta EE Developer Advocate. This means that I am able to dedicate all my time to community building and contributions to open source.
My new role enable me to be even more present at conferences and events around the World, so I expect 2020 to be at least as busy. I already have conferences lined up for the first quarter and more in the planning.
With Jakarta EE 8 out the door in 2019, we are now in full planning for Jakarta EE 9. The biggest impact of this release will be the namespace change from javax.* to jakarta.*. We will also prune some not very widely used technologies in order to lighten the burden for new implementations of the platform. This work will probably continue in subsequent releases.
All in all 2019 was a great year for Jakarta EE and I expect 2020 to be even better!
The Jakarta EE Platform Project calls are open for participation from anyone. If you are not able to attend a call, you can always browse to the Meeting Minutes for an update on the current discussion topics and decisions.
So, how do I get started with contributing to Jakarta EE?
The first thing you need to do is to create an Eclipse Account. If you already have an account, you may skip this step. If you want to do more than just joining the discussions on the mailing lists or calls, you need to sign the Eclipse Contributor Agreement (ECA). If you already have done this, you may skip this step as well.
The entire process is summarized below.
Congratulations! You can now be a Contributor to any project at the Eclipse Foundation.
So, how do I actually contribute then?
The easiest way of contributing is to submit Pull Requests to the project you are interested in. All the Jakarta EE Specification projects are currently located under the Eclipse EE4J GitHub organization.
The more you contribute, the more likely you are to be elected as a committer to the project (i.e. if you want to). If you get elected as a committer to a specification project, you will be asked to sign the Individual Working Group Participation Agreement. (*)
It has been a lot of talk about processes in the Jakarta and MicroProfile community lately, so I just want to remind us all about this item from the Agile Manifesto.
Individuals and interactions over processes and tools.
That said, some process is needed. Especially for work with specifications. In this post, I explain the Jakarta EE Specification Process and also think aloud about how the same principles could be applied to Eclipse MicroProfile.
The Jakarta EE Specification Process (JESP) is derived from the Foundation Specification Process (EFSP). The short version is that it specifies how long the voting periods (ballots) are for the various reviews:
Creation Review: 7 days
Plan Review: 7 days
Progress Review: 14 days
Release Review: 14 days
Service Release Review: 14 days
The entire process is visualized in the figure below.
So, how fast can you develop a specification using the JESP? Well, you will need to come up with a specification project proposal and submit it for review. This review may take up to 7 days to be finalized.
The next step is to present the release plan for the Jakarta EE Specification Committee for a Plan Review. This step is optional and meant as a means for the project to secure that you are on the right track. Let’s say we opt-in for this review which means another 7 days, i.e. 14 in total so far.
When your specification is ready to be released, you will submit it for a release review. This will take 14 days to complete and may run in parallel with the ratification by the Jakarta EE Specification Committee. The total amount of days in review for your specification will then be 28 days.
Without the plan review, we are looking at 21 days which is exactly the same as for any project following the Eclipse Development Process (EDP). Which applies to the e.g. the Eclipse MicroProfile project.
The difference between the governance model of Jakarta EE and Eclipse MicroProfile is that Jakarta EE is a working group and has a specification process in place for capturing the intellectual property before a specification is released. Whereas Eclipse MicroProfile is a standard Eclipse Foundation project with an ad-hoc specification process. As an Eclipse Foundation project, the project name has to be prefixed with Eclipse. As a working group, this restriction does not apply.
In the table below, I have summarized some of the similarities and differences and even taken the liberty to draw up how it could look like if a MicroProfile working group with its own specification process was established.
Eclipse MicroProfile (as a project)
MicroProfile (as a working group)
Eclipse MicroProfile [spec]
Specs Consumable by Jakarta EE
Specs Consumable by Eclipse MicroProfile
(*) Thinking aloud: MicroProfile Specification Process (MSP)
The MicroProfile Specification Process could be as simple as this: Adopt the EFSP with the following voting periods (ballots): (…still thinking aloud…)
Creation Review: 7 days (as today according to the EDP)
Plan Review: 7 days (or optional as today)
Progress Review: 7 days
Release Review: 14 days
Service Release Review: 14 days
To sum up, I think the JESP has captured the essence of “Individuals and interactions over processes and tools” by being as lightweight as possible while still protecting everyone involved.
