JBoss AS ships with Hibernate - it uses it for JPA. The JARs are in common/lib.
Specifically, the hibernate core jar has a manifest thus:
Implementation-Title: Hibernate Core
Created-By: Apache Maven
Specification-Title: Hibernate Core
Archiver-Version: Plexus Archiver
Part 2 of my question. How can I modify the JBoss AS class loader behaviour for my app in order to use the HIbernate 3.6 jars that we've packaged in the ear, .. or is there a better option..
I saw some posts earlier this morning regarding modifying the jboss-app.xml but that was for earlier JBoss versions.
