You can use MBean with ObjectName as jboss.jca:name=,service=ManagedConnectionFactory If you call the getManagedConnectionFactoryAttribute("XADataSourceClass") operation you will get the XADataSource class name , this basically comes from org.jboss.resource.adapter.jdbc.xa.XAManagedConnectionFactory method getXADataSourceClass() . http://anonsvn.jboss.org/repos/jbossas/trunk/connector/src/main/org/jboss... You can test the behavior through the jmx-console for a configured xa datasource. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4119176#...
