Java EE 6, NetBeans, and GlassFish workshop at Reykjavik, Iceland

Guest Author


The href="http://www.linkedin.com/groups/JUGICE-Java-User-Group-Iceland-102100">JUGICE
normally has about 10-25 attendees, and href="https://blogs.oracle.com/arungupta/entry/java_ee_6_pulled_crowd">once
again, the awesome threesome of Java EE 6, NetBeans, and
GlassFish attracted about 50+ attendees in Reykjavik, Iceland.

The interactive attendees learned all learned about:
  • Improvements in Java Persistence API 2

  • "web.xml"-free and annotation-driven Servlets
  • Simplified packaging of EJBs in a WAR file, no-interface and
    single file definition of EJB

  • Session preservation across redeploys
  • Facelets (XHTML/CSS) as templating language for JavaServer
    Faes to achieve true MVC
  • Integration of Bean Validation with JPA and JSF

  • Typesafe dependency injection and Producer/Observer of events
    using CDI
  • RESTful resources using JAX-RS

Most of the attendees stayed for almost 4 hrs long workshop. Several
folks gave positive feedback afterwards and tweets like this are
much more explicit about it:

Almost everybody could complete all the exercises, which was
definitely satisfying. Most importantly I coached them on how to
debug errors and got them little more comfortable in NetBeans and
GlassFish. Some folks were even asking for the next level of
workshop already. I'd love come back in Summer to enjoy the
Icelandic hospitality!



I had an interesting discussion with a J2EE-to-Spring-converted
architect on the benefits of Java EE 6 over Spring. Stay tuned on
that and I'll post more details in a few days :-)

I also had some good discussions with Reynir Hubner, the marvelous
and extremely hospitable JUGICE leader. He is the CTO at href="http://www.eplica.com/">Eplica and also the Vice
President of Reykjavik Cycling Club.
We had some interesting talks about cross training. He took me
around Golden Circle and to Blue Lagoon.
