You just have to use java:/JmsXA in your JNDI (I'm not sure about the JNDI URL in top of my head now, please google for the right one :-) ) The JCA is defined by the JCA adapter, usually on jms-ds.xml (unless you changed it in your config). Look for this: <tx-connection-factory> | <jndi-name>JmsXA</jndi-name> | <xa-transaction/> | <rar-name>jms-ra.rar</rar-name> | <connection-definition>org.jboss.resource.adapter.jms.JmsConnectionFactory</connection-definition> | <config-property name="SessionDefaultType" type="java.lang.String">javax.jms.Topic</config-property> | <config-property name="JmsProviderAdapterJNDI" type="java.lang.String">java:/DefaultJMSProvider</config-property> | <max-pool-size>20</max-pool-size> | <security-domain-and-application>JmsXARealm</security-domain-and-application> | </tx-connection-factory> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4159016#...
