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.

Subject: [rules-users] Task Server gives error cannot use getTransaction()
When I configure the Task Server(org.drools.task) to be JTA I get the following error when
adding a Human Task work item. Is the following Persistence Unit configuration valid?
It works when the org.drools.task trans type is set to LOCAL_RESOURCE.
Using drools 5.1.0.M1 in JBoss 5.1
