Have any of you successfully used JEE 6 specific features in your solution? I mean EJB 3.1, CDI, JAX-RS, JSF 2.0, packaging EJB in WAR, and so on.
I have already searched forums for this question, but found very different answers so far.
I know this is Java EE 5 certification, but my assignement doesn't enforce any min/max JEE version. It just says that the architecture must be built using the JEE platform.
