How Popular Is Actually Java EE 6?

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.

Love your blog,

the few slides were in English - the sessions were hold in German.

During the workshop I explained everything in the IDE - I used the slides only as captions.

Java EE 6 is as simple - so that not lot of slides were needed :-)

Hi Adam,
Glad to know that Java EE 6 interest is rapidly increasing. I'm wondering if you had any discussions with the attendees on using front end technologies other than JSF within Java EE 6 environment?

I hacked a JSF 2 sample with Bean Validation, CDI, EJB 3.1 and JPA 2.0 "on stage". We discussed the differences to wicket, zkoss, flex, seam, Java FX and GWT in particular.

I was asked about seam, gwt and wicket by the attendees in particular,

thanks for your comment!,

Thanks for your reply Adam. That would have been one cool session to be part of. Would you mind sharing what primary concerns/doubts/problems raised by attendees wrt above mentioned front end technologies. I worked on ZK CDI extension and I am trying to learn how I can make better/easier so that ZK developers have seamless access to CDI features in a ZK application.

hi adam,

i was a attendee on your monday workshop during the jax conference. it was really a good session, where i learned much about the simplicity in Java EE6. Back in business i'll try to do some things easier now :-). Also your 'agile' presentation mode and the way you managed the session was impressive.

see you on another jax in future.

greetings, enjoy

I saw your keynote at the JAX2010. It was very interesting and entertaining. Afterwards I bought me your book Real World Java EE Patterns.

Maybe you can answer me a question: You write about the Hessian protocol, which can be used as communication protocol. Can you provide an example how I can achieve this with JBoss and a client?

Kind regards

Does it make sense to spend time learning Java EE 5 or do you think someone who is starting should go to Java EE 6 straight up?

The advantage I can see with EE 5 is the availability of servers from commercial vendors such as Weblogic & Websphere.

What do you suggest?

Hi Adam,
In case your readers are interested there is an excellent article on IBM developerworks on CDI programing in ZK
