Hi gaohoward, Thanks for your reply. I followed the examples but there is no sample with IBM MQ. I tried with the below conf without luck. I get the "java.lang.IllegalArgumentException: Connection factory must be XAConnectionFactory" with the following conf. Please let me know how to make IVTCF XA enabled. wmq.jmsra-ds.xml --------------------- <connection-factories> | <!-- connection factory definition --> | <tx-connection-factory> | <jndi-name>IVTCF</jndi-name> | <xa-transaction /> | <rar-name>wmq.jmsra.rar</rar-name> | <connection-definition>javax.jms.ConnectionFactory</connection-definition> | <config-property name="channel" type="java.lang.String">WAS</config-property> | <config-property name="queueManager" type="java.lang.String"></config-property> | <config-property name="transportType" type="java.lang.String">BINDINGS</config-property> | <security-domain-and-application>JmsXARealm</security-domain-and-application> | </tx-connection-factory> View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4250958#...
