I am very happy to be back at JavaZone in Oslo this year with a talk called MicroProfile – by Example. In this talk, I will describe the history and reasoning behind the Eclipse MicroProfile initiative, provide code samples and strategies for using all implementations and also introduce the newest addition to MicroProfile – MicroProfile Config.
Of course, there will be lots of demo and code…
When Oracle announced that MVC 1.0 was withdrawn from Java EE 8, they also indicated that they were investigating a possible transfer to a community member or organization for completion as a standalone JSR. True to their word, a request for a transfer ballot of JSR 371 has now been submitted to the JCP Executive Committee.
I am happy to announce that I will be the receiving part of this transfer and thus will take over as Spec Lead for JSR 371.
So, why would I want to take over a JSR that ranked so low in the Java EE Survey? Well, there are several reasons for that:
First of all the incredible community support and interest there is for MVC 1.0. For example, JSR 371 is the most widely adopted JSR by Java User Groups participating in the Adap-a-JSR program. No less than 8 JUGs have adopted this JSR!
Secondly, I feel that the wording of the question in the survey may have played a role. The question for MVC was “How important is MVC API for the next generation of cloud and microservices applications? (1=Not Important, 2, 3, 4, 5=Very Important)”. Still, 505 responded Very Important and only 361 Not Important. The rest were pretty evenly distributed. See Java EE Survey Results for the complete numbers.
Third, only 1693 surveys were completed worldwide. Out of 10 million Java developers, this is an alarmingly low number taking into consideration that the survey was open for more than a month and there were massive encouragements for participation from the community, including Oracle.
Fourth, in the Java EE Guardians survey that was performed just prior to the Java EE 8 survey more than 30% of the respondents answered Very Important to the question “How important is it to add a new action-oriented MVC framework to Java EE?”.
The Way Forward
The most important thing right now is that the request for transfer is approved by the EC. The ballot closes January 30, so shortly after that the practical work may start.
You have probably noticed that the Java Community Process (JCP) has made becoming a member much easier. There is a new membership level called Associate Member which does not require any paperwork or approval of your employer and it can all be done online filling out a simple form.
Why should you become a member?
– It looks good on your resume
– You can join as a contributor to any JSR and help evolve the Java ecosystem
– You get a vote in the upcoming elections for the Executive Committee
Why is the last item important?
Well, I am running for an associate seat in the EC, so by joining the JCP and voting for me in the upcoming election, you make sure that your voice is heard at the very top level of the JCP. My motivation is to give as much power to the community as possible.
Let’s make the JCP Great Again!

As mentioned in Aggressive Road Map for Java EE 8, MVC 1.0 is left out of the plans for Java EE 8.
The way I see it, and also have indications from several people I have talked with during JavaOne, the possible outcomes of this are:
1. MVC is dropped completely
2. MVC continues and is included in Java EE 8 (JSR 366)
3. MVC continues as a standalone specification outside of the Java EE 8 umbrella spec
Let’s cross our fingers that the survey result turns out positive for MVC and that option 1 is ruled out by the community.
If we’re honest, option 2 is probably not very likely to happen. Given the aggressive road map for EE 8, cuts will need to be made. And MVC certainly isn’t on the list of the preliminary proposal.
Then we are left with the third option. And I actually think this may be the best way for MVC. There are several reasons for this:
MVC will not be depending on the Java EE 8 release and may release earlier and more oftenJava EE 8 is going to include some form of modularity and MVC may very well be one of these modules no matter if left out of EE 8. There are also some considerations to take if this option is explored
Ozark needs to be made portable across Java EE implementations. This means that we will need to get rid of the dependencies on internal Jersey APIs and base the entire implementation on APIs and SPIs that are available in Java EE 7 (and later Java EE 8 and 9)TCK
An open TCK under for example Apache 2.0 will enable us to easier use community input for developing the TCK. If Oracle is willing to let go of the TCK, they will also be relieved of the cost of creating it. This actually also applies to Ozark. It would be great if it could be developed under e.g. Apache 2.0
So, what you should do is to fill out the survey by following the link below:
The Java Community Process (JCP) program 2016 Executive Committee (EC)
Elections have started. This is the first election to be held under the newest JCP 2.10 Process Document rules.
One of the new things introduced is that there will be two Associate Seats in the Expert Committee. These seats are elected by the Associate members of the JCP.
I have nominated myself for one of these Associate Seats. See my position statement below.

Java 7 is finally here! Or to be absolutely correct, will be released July 28. In this post, I will point out 7 (wonder where I got that number from…) reasons to upgrade.
- Coins are also money
Project Coin contains a couple of nice language changes that will make life as a programmer much easier. See the project page for details.
- Dynamic languages
invokedynamic adds support for dynamically typed languages on the Java platform.
- New File System API
File operations have always been pain in Java, but with this new API most of the issues are solved. Manipulating symbolic links for example.
The Fork/Join Framework provides a set of utilities you would benefit from when writing concurrent programs, giving the possibility for true parallelism on the Java platform.
A refactoring enabling the Java SE platform to be downloaded as required by the VM as needed.
A lot of enhancements regarding classloading, unicode, locale etc.
- It’s new
And new things are always more motivating to work with than old, at least in the context of programming languages.
To be honest this is not very much for a major version of a programming language, especially since it has gone nearly five years since the previous version. But it shows that Java is still alive after the whole Oracle story.
Usually, when I come home from work, I am pretty tired of programming and rarely ever do any programmin during weekends. But this weekend was different. I have been coding pretty much at work lately, so it should not be because of abstinence from coding. Anyhow, I set down and contributed to a small open source project started by a former colleague of mine. It is called Architect’s Java DAO Generator, and you can find it on Sourceforge. In short it is a maven plugin that generates most of the boilerplate code you usually have to code by hand. It also abstracts the data access layer from your domain logic in a nice way. Version 1.5 is soon going to be available and is absolutely worth a look.
