Maybe you missed some property there? I was looking on how this is configured on EAP, and this is what we have there: | <properties depends="arjuna" name="jta">^M | <property name="com.arjuna.ats.jta.recovery.XAResourceRecovery.JBMESSAGING1"^M | value="org.jboss.jms.server.recovery.MessagingXAResourceRecovery;java:/DefaultJMSProvider"/> | <!-- | Support subtransactions in the JTA layer? | Default is NO. | --> | <property name="com.arjuna.ats.jta.supportSubtransactions" value="NO"/> | <property name="com.arjuna.ats.jta.jtaTMImplementation" value="com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionManagerImple"/> | <!-- | com.arjuna.ats.internal.jta.transaction.jts.TransactionManagerImple | --> | <property name="com.arjuna.ats.jta.jtaUTImplementation" value="com.arjuna.ats.internal.jta.transaction.arjunacore.UserTransactionImple"/> | <!-- | com.arjuna.ats.internal.jta.transaction.jts.UserTransactionImple | --> | </properties> | Also.. make sure you have DefaultJMSProvider at your jms-ds.xml.
