Hello all,

How do I do to use a JBoss patch directory for Hibernate jars?

If I move {$JBOSS_HOME}/common/lib/hibernate-core.jar out to a directory outside  {$JBOSS_HOME} (like /home/jens/patchdir/), create a simple JEE app (EAR with Servlet in WAR, accessing SLSB and Entity in a JAR) with once entity and start up jboss with the patch directory flag...

bin/run.sh -p "/home/jens/patchdir/"

...jboss will note that this patch directory is used and obviously find the classes, but on startup of app throw an IllegalAccessError:

11:14:41,912 DEBUG [PersistenceUnitInfoImpl] Found persistence.xml file in EJB3 jar

Using JBoss 5.1 with JDK5.

The real Use Case is that I've patched hibernate-core.jar in Hibernate 3.3.1 and would like to start up JBoss without having to replace internal jars, but once that didn't work I simplified the test by trying to use the standard hibernate-core.jar in a patch directory.

br,

Jens
