Anyone used JEE 6 features in solution?

Hi!
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.

I haven't used in my assignment, intention was to be with JEE 5.

Yes, I have used JEE 6 with EJB 3.1, JSF 2.x, etc in my assignment. The proposed solution should be JEE 5 or above.

Hello Shekhar,

Have you submitted your Part II already? Any issues/rejections for reasons of using JEE 6 featurs?

Thanks!
