Thanks for replying, Does this mean if I have to do batch commit then I have to grab connection and set its auto commit to false. Do I need to set the connection autocommit back to yes once finished? For WebSphere and WebLogic, connection obtained from DataSource seems to have autocommit false. Is there any way to get the same behaviour for JBoss without code changes?
