Hello,
I have an application which uses Hibernate in the data access tier fronted with
Spring DAOs. On top of this standard architecture I added a thin EJB layer:
Stateless Session EJBs wrapping the Spring business objects. The application
deploys and runs fine. I am able to run a client Java program calling a method
on a session bean which works correctly.
When I try to redeploy this application without restarting JBoss, and run my
client again I get the error below. Restarting the server fixes the problem.
Any help in resolving the hot deployment issue is greatly appreciated.
