I'm currently looking at http://jira.jboss.com/jira/browse/JBPAPP-750 with the integration between the EAP and JBossMessaging since JBM implements both the non-XA and XA interfaces. XA mode is selected at session level. 1) Is the best way to handle this to extend the JmsConnectionRequestInfo class with XA information - f.ex. UseXA - and then use this information when creating the sessions in JmsManagedConnection::setup() ? Of course there will be other changes also JmsMCFProperties, ... Creating f.ex. a JmsXASession class may be an idea. 2) JmsActivation also need information about XA from JmsActivationSpec in order to create the correct connection type - so UseXA here. Any feedback on how this should be done is most welcome View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4142342#...
