[jboss-user] [EJB 3.0] - "No Classloader Found" During JBoss-Hibernate Deployment

Saturday, 22 November 2008

I am getting a "No Classloader Found" exception during the deployment of my
Hibernate Application on a JBOSS server. I have provided the full stack trace along with
the relevant Hibernate cinfiguration and mapping files below. Any help you can provide
would be GREATLY appreciated as I have been stuck on this problem for several days now.
Thanks
