Hi,
I am trying to make some data persistent in to the database and using hibernate
for that.....i am doing this through a session ejb......I have a client where i am
calling addItem(item) method.....
Problem is in client program.....i am stuck there itself.....
i get the following error....
I am using JBoss3.2.3, Hibernate 2.1.4, MySQL4.0
java.rmi.ServerException: RemoteException occurred in server thread; nested exception
is:
