MevenIDE + NetBeans + Enterprise Applications

Hi,
We try to use for our Enterprise Application project Maven2 (MevenIDE) and NetBeans 6.1. We have had problems with plugin 3.1.x so feature-3.2-snapshot has been used instead.

We have noticed that some Netbeans fatures are disabled or does not work, like: Enterprise Resources (popup menu in EJB file, menuitem is disabled) and New File->Persistence->Session Beans for Entity Classes. Null Pointer Exception is thrown in the second case. It is not a problem for us to manually create facades for entities or inject ejb, but these creators are very convenient for our students.

Regards
