About: JBoss3.2, Hibernate2.1.6, closing Hibernate Sessions/Connections.
-slsb uses SessionFactory to get a Session
-own hibernate SessionFactory impl which when handing out a new Session in getSession() registers a new javax.transaction.Synchronization handler instance with the the TM.
-the aim of the Synchronization handler is to close the Sessions in beforeCompletion / afterCompletion
Q: is this design broken? On reading your post http://www.jboss.org/index.html?module=bb&op=viewtopic&t=49041 i started wondering if what i'm doing is such a good idea (open connection in context of ejb, closing it at the end of the tx).
The Problem: This approach seems to work ok until my beans start calling other beans with tx attribute RequiresNew. Which is where i get said IllegalStateException: Trying to return an unknown connection2 when my Synchronisation handler tries to close the Hibernate Session.
Also ConfigCachedConnectionManager has SpecCompliant=false, Debug=false...
I'm not sure if what i'm describing is related to all the other reports of this exception.
