I'm in the same boat, getting these '[PropagationContextManager] jboss-atx: unknown Tx Propagation Context' messages. It seems that I've made progress however. I've uncommented the following section of jboss-4.2.3.GA/server/all/conf/jboss-service.xml headed by this text: | <!-- | | The fast in-memory transaction manager. | | Deprecated in JBossAS v4.2. Use JBossTS JTA instead. | --> | And then I've commented out the section headed by this text: | <!-- JBoss Transactions JTA --> | I think this effectively reverts to the 4.0.3SP1 transaction manager.
