Sorry... I was wrong on something there (at least one thing ;) ).... I am getting an XAResource enlisted into a new transaction (org.jboss.soa.esb.listeners.jca.EndpointProxy:326:branches/JBESB_4_4_GA_CP) when I use the WMQ Adapter config (option #1 above). So what's the magic for getting the com.ibm.mq.jms.context.WMQInitialContextFactory class to create an XA Connection Factory (com.ibm.mq.jms.MQXAQueueConnectionFactory I assume) using direct JNDI?? As you can see from my config above, my non-JCA listener config is: | <jms-provider name="IBMMQ" jndi-URL="localhost:1414/SYSTEM.DEF.SVRCONN" | jndi-context-factory="com.ibm.mq.jms.context.WMQInitialContextFactory" | jndi-pkg-prefix="" | connection-factory="ConnectionFactory"> | | | <jms-bus busid="quickstartEsbChannel1"> | <jms-message-filter dest-type="QUEUE" dest-name="WMQESBAWARE1" transacted="true"/> | </jms-bus> | | </jms-provider> | Any ideas?
