Hi All ,
I am using JBOss 4.2.0 server and toplink aling with Oracle 10g to persist the entity bean and on deployment I get this warning :


12:39:16,187 INFO [STDOUT] [TopLink Warning]: 2007.07.05 12:39:16.125--java.lang.NullPointerException: null was thrown on attempt of PersistenceLoadProcessor to load class src.Employee. The class is ignored.
12:39:16,187 INFO [STDOUT] [TopLink Warning]: 2007.07.05 12:39:16.187--java.lang.NullPointerException: null was thrown on attempt of PersistenceLoadProcessor to load class src.FirstSessionBean. The class is ignored.


I guess , perhaps because of this problem later on making a call to persist the entities I get this error as :

I think someone else had this same problem recently.

The problem is that the JBoss container does not correctly implement the pluggability contract. You can go ahead and use application-managed Entity Managers if you ignore these errors and just create the EntityManagerFactory using Persistence.createEntityManagerFactory, etc.
