Try using org.jboss.resource.connectionmanager.TxConnectionManager instead. | I don't see why the EAR should be using the LocalTXConnectionManager , the JCA ConnectionManager is transparent to the application developer . LocalTXConnectionManager was present in the older Jboss verisons and it is not longer available in latest versions , removal of LocalTXConnectionManager should not make failure in the EAR .
