Devoxx Day Four - part 2

The "JavaFX in the enterprise" session showed a lot of the JFXtras project which is a step in the right direction but I think still a lot of work has to be done to make JavaFX usable in the enterprise.

The iBeans framework offers easy integration without using a full SOA. Simplifies the development of a small app/widget with integrates a lot. I found it a bit annotation heavy.

Glassfish v3 I saw already the previous time at Devoxx. Still an impressive application server, I will surely check it out when it comes out 10/12/2009. Before the demo, Roberto Chinnci explained a bit the extensability of JavaEE 6 at servlet level through ServletContainerInitializer subclasses and the dependency injection through an Extension implementation. I won't go into details but basically, you can by adding a jar to your classpath, dynamically add servlets, servlets and beans when the app starts up. Very powerful and a blessing for the common developer onces the frameworks start using this. No more configuration but pure magic.

Last session performance. I have to agree with the speaker which is from IBM Support Assistant. Performance is only an issue when it's bad. The techniques explained for finding CPU, I/O, memory of lock problems often involved some sort of tool. Still experience in understanding the returned data is often more important than the used tool.
