It’s this time of the year again. Time for the yearly summary of conferences, travels, community activities, open source projects, amazing people!
Like most recent years, I have been speaking at quite a few conferences around the World. The countries I visited as a speaker in 2018 were Sweden, Germany, USA, England, Denmark, France, Belgium, South Africa, Australia, and New Zealand.
Another acknowledgement by the community was to be re-elected for an associate seat in the JCP Executive Committee.
Besides speaking at conferences, a great deal of my time in 2018 was dedicated Jakarta EE at the Eclipse Foundation where I act as the PMC Lead of EE4J a well as being a member of the Steering-, Specification-, and Marketing Committees in the Jakarta EE Working Group.
All in all 2018 was an eventful year and I expect no less of 2019!
This is all very good, excellent actually! When you think about the size of it all, it is actually quite an achievement. We are talking about 7.7 million lines of code! More than 60.000 files and a total of 38 new projects that have been set up at the Eclipse Foundation.
But, as everyone knows, developers are impatient and eager to try out everything new, so there are still a couple of questions that I always get when talking about Jakarta EE:
When can I start developing Jakarta EE applications?
The answer to the first question is: “not yet”. Until the Jakarta EE specification process is finalized, the technologies are still Java™ EE.
The answer to the second question differs a little depending on who you ask, but usually is something in the lines of “I am pretty sure that some of the MicroProfile specs will be integrated into Jakarta EE when they have proven to be useful”.
NO, here is what you should do: Use the power of Java™ EE 8 and combine it with Eclipse MicroProfile.
Many of the application server vendors have added MicroProfile features to their Java™ EE 8 compliant or certified application servers. Examples are Open Liberty, WildFly, Payara and Apache TomEE. See the respective vendor’s documentation for which versions they have included.
I have put together a simple application called Jakarta EE Duke to demonstrate how to do this. The application uses the @ConfigProperty annotation from MicroProfile Config to configure a message as well as the new @Email annotation from Bean Validation 2.0, which came with Java™ EE 8 to validate input.
While this example is extremely simple, it does indicate how you can combine the full power of Java™ EE 8 with the lightweight APIs of MicroProfile to implement cloud-native microservices using Java™ technology.

There is a lot of work to do, so every contribution is appreciated, especially regarding setting up the CI/CD pipelines for all the EE4J projects. Take a look at our status sheet and sign up where you think you can contribute.
One of the requirements for Eclipse Projects is that the name is not associated with any trademarks or potential trademarks. When we created the project proposal for Ozark, this turned out to be the case here. The name Ozark is simply used too many places for it to be a valid Eclipse project name.
So, how did we come up with the new name? First of all, we asked for input on the Ozark developer mailing list. We also wrote a small program that generated all permutations of ‘ozark’ to see if something cool came out of that.
Then we started filtering, discussion and voting until we ended up with Krazo, which turns out to be Ozark spelled backward. We are really excited about the new name and hope you all will join us in spreading the word that the reference implementation of MVC 1.0 that was previously known as Ozark is now called Eclipse Krazo.
I should be honest and say that it wasn’t my first choice when I voted, but when I see it in use with different colors and backgrounds, I must admit that it looks pretty good.
The initial strategic and participating members of the Jakarta EE working group are also listed on the website.
It is pretty awesome to see this list of companies participating and supporting Jakarta EE! And the list is likely to expand as more companies join. The future of Cloud Native Java is Jakarta EE, and the future looks bright. Let’s set the sails and sail towards the future (finally got the logo, I think…).
The Jakarta EE name has been out for about a month, and even if Mike Milinkovich explained the names and concepts pretty well in his blog post And the Name Is…, there still is a bit confusion about how it all relates and I get questions around it whenever the topic comes up. I have tried to sum up some of it here. Hope it helps!
Java EE, or Java™ Platform, Enterprise Edition, is the name of the current platform governed by the Java Community Process (JCP). The latest version is Java EE 8, which was released in September 2017.
Eclipse Enterprise for Java (EE4J) is the top level project in the Eclipse Foundation for all the projects for creating the standards that will form the base for Jakarta EE. The EE4J Project Management Committee (PMC) is responsible for maintaining the overall vision for the top level project. It will set the standards and requirements for releases and help the projects communicate and cooperate.
Jakarta EE does not replace Java EE! It is the name for the platform evolving with Java EE 8 as a starting point. Java EE 8 will still exist, but there will not be any new versions of the platform.
Jakarta EE does not replace EE4J! It is the name of the platform based on the EE4J projects with Java EE 8 as a starting point.
I could probably write a long post about why my vote goes to Jakarta EE in the vote for new brand name to take over after Java EE, but it feels much more appropriate to refer to David Blevin‘s excellent description of the process in his blog post Java EE to Jakarta EE.
It has been tough on us keeping these discussions secret since we are all working for an open community and want to share everything. But the importance of securing a name that we as a community can trademark through the Eclipse Foundation makes it well worth the efforts.
I just came off a phone call where Oracle were briefing community members about their announcement to open up Java EE. The process has just started and, understandably, there are currently more questions than answers.
Oracle finds Java EE to be very successful
Millions of applications are using Java EE
Oracle plans to continue support of Java EE
Java EE 8 will be completed as planned
Java EE 8 will also be certified on Java SE 9
By stepping aside and relicensing the technologies to an open source foundation, Oracle hope to address the perception about the openness, agility and flexibility of the current process. What this will actually mean to the Java Community Process (JCP) is uncertain. It will at least have to go through some reform to accommodate the new licensing terms.
One thing to note here, and something that is a really big thumbs up to Oracle, is that they are now informing and including the community and key players in the process from the start.
I have been giving it a try and is actually pretty satisfied with it. Even though I am not as familiar with all the shortcuts as I am with NetBeans, it feels comfortable. It does not differ that much. The only problem I have encountered with the default setup is the shortcut for comment/uncomment code (Shift+/). But this is mainly because I am using Swedish or Norwegian keyboard setup where the / is entered by hitting Shift+7. This was easily fixed by adding Ctrl+Shift+7 as a shortcut combination.
I could not find a live template for test methods, but it was easy to create a new one. Here is a simple example:
I am not sure if I like the way multiple projects are handled. If you work with multiple projects in IDEA, each project is opened in a separate frame. In NetBeans you can choose to have multiple projects open in the same workspace and/or group them in project groups. It is probably just a matter of habits, but I like the flexibility to be able to decide that myself and not be forced to open every new project in a new frame.
To conclude, I really like IDEA Community Edition, an will most probably choose use it when I am working on a project where I am in no direct need of Java EE support in the IDE. Otherwise, NetBeans is still my favorite IDE. Eclipse is still out of the question as long as Maven is involved.
