I'm back from the JAX 2010 - one of the biggest european Java conferences. There was lot more interests in Java EE 6, than expected:

1. The "Simpler? - Is Impossible - Java EE 6" Workshop was fully booked - with 75 reservations. The actual number of attendees was approx. 100-150. Even the repetition at the very last day was well attended (12-20 attendees I had far more attendees at the end, than at the beginning :-)).
2. The "60 Minutes With Java EE 6" talk was also well attended - it took place in one of the biggest rooms (the keynote room).
3. We got a table with the topic "Weightless Beans" for the open space part of the conference. Because of the number of attendees, we had expand to the next table near us - and had a lot of fun and nice conversations about Java EE 6 (EJB, CDI, JPA) and the craziest errors in production.
4. Java EE 6 trainings are almost sold out. I increased the max-number of attendees to 20.
5. We asked the audience after our (Peter Rossbach, a Tomcat-Committer and me) Tomcat + openEJB session, who would be interested in a Tomcat+EJB distribution. More than half attendees were interested.
6. Several conference attendees reported me that they are in the process of migration to Java EE 6 ...from Java EE 5

JAX was really nice conference with great food and interesting topics. Already looking forward to W-JAX! Thanks for attending the workshops, sessions - your feedback is highly appreciated.

...One of my personality quirks that makes my "what's next" question more difficult is that most of the things that interest me are science projects rather than sensible business plans. I'll be having fun....

I tried to make a sit reservation for an ICE (a nice train - perfectly suitable for hacking or writing). Because I travel a bit, I'm a bahn.comfort customer - its something like frequent flyer.

1. bahn.comfort service is location agnostic: the implementation of the service on the other side (another clerk), could sit whenever he want. I even suspect he was in the same room :-)
2. The interface (=phone) is very generic. Everything is replacable - even the telephone-device.
3. Built-in throughput throttling: there was only one shared phone used by three clerks (what I observed): the guy (a singleton) on the other side couldn't be overloaded.
4. The whole process is highly available: the clerk who called the bahn.comfort service tried to reach someone several times until the eventual success. He also wrote down the ID on paper (this can be considered as TX log or persistent message). Now the clerk itself is replacable, another clerk could just complete the process having the Id
5. The whole process is consistent: I stayed in touch with him and could react to any system-exceptions (like busy line). There is no need for rollbacks or compensative transactions, because he could ask me (the end-user) how to further proceed
6. Cloud ready: partially it seemed like the clerk tried to reach someone in the clouds :-)

1. Java EE 5/6 Patterns in Hamburg (26.04-30.04.2010) - some (3-5) places left
2. 60 minutes with Java EE 6, 04.05 at JAX conference - this should be fun. I will hack a Java EE 6 application in 60 minutes on stage. Still no idea which one - but suggestions are highly appreciated. I will use Java EE 6 - and so less slides, than last year for explanation (Java EE 6 is even simpler, than Java EE 5) :-).
   *After the session*, we will discuss Java EE 6 / EJB / JMS etc. features, problems and workarounds during the "open space" part at the JAX conference. Watch the table "Weightless Beans" in the Ballroom.
3. Simpler is Impossible. From UI to Integration Layer with plain Java EE, 03.05.2010 (at JAX Conference)
4. End 2 End Java EE 6 in Munich (07.06-09.06.2010) - this one is almost sold out

Oracle's official GlassFish roadmap (also clustering, HA and Java EE 7, GlassFish v4) summarized on 14 slides. The excellent Java EE 5/6 portability (vendor-neutrality) story and this slide deck should give GlassFish the next popularity/adoption boost.
[I borrowed the title from slide 4]

It's sad, but James Gosling leaves Oracle. I'm really curious about his next job...
An excerpt from his bio: "...He briefly worked for Oracle after the acquisition of Sun. He is now blissfully unemployed :-)..."

Attributes in a class don't have to be declared in the verbose way:

public class VerboseClass {
    private String firstName;
    private String lastName;
    private String description;
}

public class CompactClass {
    private String firstName,lastName,description;
}

It was already obsolete for a long time - now it happened. So let the forking begin. Now Geronimo + Glassfish are a part of the same family :-).

The Ubivents event platform is written Java FX and seems to be used by SAP:

"...Their platform is used by large corporations like SAP, and they have generously offered to host our videos going forward. Therefore, you can now watch all the SvJugFx videos using JavaFX technology!..."
