I’m afraid that I haven’t been able to get past the issue in which JBoss’s 
version of Hibernate (3.6) is used instead of my version of Hibernate (3.2.6) 
which is deployed in WEB-INF/lib as evidenced by the stack trace…

Here's the log entry proving that my WEB-INF/jboss-classloading-domain.xml file 
is being referenced (as expected)...

This issue is unfortunately blocking our migration from JBoss 4.2.3 to JBoss 
6.0.0.Final.
