Connections obtained from the xa-datasource Or local-xa-datasource enlists the XAResource associated with the Connection in the ongoing Transaction (TM) , this is mentioned in the JCA specs . All you need to do is to configure the JOTM in Jboss , then things would work perfectly . I would not advice you to go with JOTM (TM) implementaion , you can go with the Arjuna which comes with Jboss as default . I am unable to find the link explaining the configurations details of JOTM in Jboss . View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4116798#...
