Java EE (Java Enterprise Edition) General Discussion

Hey all,


Ok I have a many smaller JSF web app thus far i have got away with writing JDBC code with a bit of springs JDBC abstraction, But i have a project coming up that is going to get ugly with this approach.


Just wondering if anyone has any opinions on which persistence layer technology I should use I have read a bit about the two but never really used them.

I need something that is powerful and preferably easy/quick to learn.

I realise hibernate is now considered (mature) not sure if this will impact its use in the future but also not to sure about EJB with the long java update lifecycle.


Just after some opinions on which road to take and if anyone has some good links to doc's tutorials etc would be helpful.


And is Seam worth looking at for the EJB approach?
