Hello again
I tried to add a name to the ejb to identify it from the java class :
@PersistenceContext(unitName="amcontext") public EntityManager m_manager;
but the error are still there. I cannot see where to go and I'am blocked
in my project
I really need help
Is there anybody using entity manager with resin 4.0.37 ?
Thanks.
