That's correct. The current WSHT implementation (Drools Task) uses JPA entity manager to get hold of transaction which will not work if the transaction-type configured as JTA. http://java.sun.com/javaee/5/docs/api/javax/persistence/EntityManager.htm...

Is the following Persistence Unit configuration valid? It works when the org.drools.task trans type is set to LOCAL_RESOURCE.
