Sorry, Emmanuel, I didn't reply before because I really didn't have a clue; my understanding of this just came from following code from the exception stack trace. But, now QE has stumbled onto this and raised a blocker JIRA (http://jira.jboss.com/jira/browse/JBPAPP-90). Are you saying hibernate.session_factory_name is the JNDI name? Or the value of the persistence-unit 'name' attribute? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4030806#...
