Adam made it in an hour and presented many interesting topics. He started with new subjects introduces in JEE6, like optional local interfaces, cronjob-like Timer Service and other nice goodies. Then he covered new stuff from JEE like REST and CDI (Context and Dependency Injection). Finally, he moved to the best practices, patterns and anti-pattern. As usual, it was quick and precise – Adam answered many questions and gave a good overview of the technology.

After the presentation, JUGHH / Lehmanns offer a glass of sparkling wine for the smaller audience and Adam spoke about the possibility to speak about JavaFX next time. This time I left my camera at home and only had my phone with me, so sorry for the low-resolutioned picture…

Yesterday, the second Adam Bien event in Lehmanns Bookstore took place. Again, the event was a full success. I arrived half-an-hour earlier and got a seat only in the tenth row.
Adam spoke about new features of EJB 3.1 and Glassfish. He showed examples running on a developer build of Glassfish V3, promising that the features will work without exceptions…
Here are some topics, I remember:

• Singleton Beans: usefull a s a central point of the application, e.G. central cache etc…
• Async Methods: allows asynchronous execution of time-consuming methods. Especially, it is possible to abort the execution
• Deploying Beans in WARs: could be helpful for small applications
• Global JNDI-Namespace
• No interface view: simplifies the access to beans, if needed
• EJBCOntainer.getEJBContainer().getContext(): allows external initialization of bean context, which is nice for testing

Later, Adam discussed some Core J2EE patters, that become absolete with EJB 3.1 and others which are still valid.

After the talk, I spoke with Adam about the OSGi as a module architecture inside JEE application, which seems interesting to me.

The pictures are as usual available in my FlickR Gallery.

Marco published a video on Loroma.

This session will be interactive / openspace like. He will walk through the new EJB 3.1 APIs and explain some interesting stuff as well. It is the logical conduction of the first JUG HH session in May 2008.

Topic: Productive Java EE 6 – Rethinking Best Practices And Bashing On Patterns, Cluster One

Abstract: Java EE 6 is great, but many questions like:

• Are DAOs dead?
• Do JSF really suck?
• Are anemic JPA-entities a best practice?
• Are XML deployment descriptors legacy?
• Are EJBs lightweight?
• How to test EJBs?
• Is layering an antipattern?
• Do we need factories?
• How to integrate with RESTFul services?
• Is it possible to deploy EJBs into a …WAR?
• Are “plain old web containers” dead?
• Services or Objects – what is the way to go?

still remain open. These and many other questions will be discussed interactively with …code.
