I have not been able to locate anyway to create a EJB 3.0 Entity in your latest trial. Is this not supported? That seems to be very odd.
In addition it looks like your Hibernate support is broken. I selected Hibernate as a module for my project and I ended up with it unable to download files.
It looks like your latest version is lacking behind NB for JEE5 support which is a disappointment since I was hoping to make use of your Groovy support but full JEE5 support is of much more importance. I also would like to try out BEA Kodo for the JPA but it looks like you only support Hibernate and for that not even the JPA?
