No ClassLoaders found
JBoss 4.0.3 sp1
I just tried to turn on the JBoss TreeCache in Hibernate. When Hibernate tries to place an entry in the cache, I get a ClassNotFoundException. It appears that the TreeCache can't find the classes that are inside of my ear. I am using the jboss.cache:service=EJB3EntityTreeCache cache.

Is this supposed to work? Any suggestions on tracking down the problem?
