Hi there, I've just started using JBoss AS 5 so excuse me if I'm missing something obvious...
I have a problem with EJBs I'm deploying to a JBoss 5.0.0 GA installation. Some of the entities I'm deploying cause the following error to occur during deployment: ... 14:11:15,750 INFO [SessionFactoryImpl] building session factory 14:11:16,812 ERROR [BasicLazyInitializer]

exceptions. I've seen some similar problems in the forums and on JIRA for both hibernate and JBoss projects...see these: https://jira.jboss.org/jira/browse/JBAS-5254 http://www.jboss.com/index.html?module=bb&op=viewtopic&t=83199&postdays=0&postorder=asc&start=0 In older versions of JBoss it looks like you can switch Javassist for cglib. I could not get this to work in JBoss 5. Anyone seen this before? All advice/assistance gratefully accepted.
