Even in JBoss AS you shouldn't be using the DummyTransactionManager. The GenericTransactionManagerLookup would locate the JBossTransactionManager, which comes with JBoss AS. There is no such thing as a JBossCacheManager. What I was talking about was a JTA compliant TransactionManager. To bind JBC to JNDI use a startup class which instantiates and binds a JBoss Cache instance. See http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossCacheAndWebLogic - the example is for WLS 8.1, but I'm sure the concepts apply to WLS 10 as well.
