[jboss-user] [EJB 3.0] - NullPointerException when deploy EJB's

[Nopalin]

Hi, i have been working with netbeans 5.5 and jboss-4.0.3SP1.

I have a project that works very well. When i switch to netbeans i had to migrate my project, all fine, but when i created a new EJB Stateless deployment fails. This is the statckTrace generated by jboss :

i dont know what the problem is because my new EJB is equal to other (the same annotations).

Thank you
