Let see if I can explain this: Description: I am using JBoss+JPA[Java Persistence API]+Hibernate as Persistence Manager [don't know TopLink Essentials yet]+Spring2.0+JDK1.5+Tapestry4.1[Ajax]/Hivemind+maven2+cargo Problem: I'd like to use JTA instead of RESOURCE_LOCAL I had to add java:comp/UserTransaction in conf/jboss-service.xml since it doesn't appear to be there Finally, it doesn't seem to find the UserTransaction java.lang.ClassCastException: org.jboss.tm.TxManager Somebody any clue? ps: I tried the same conf on WebSphere 6.1 [IBM's JDK 1.5] using the below conf it works.
