As you have decided not to return XA_RBTIMEOUT then setTransactionTimeout should always return false. Ok, so we don't allow the TM to set the timeout. I'll add a configuration attribute to set the JBM default timeout so we can configure it at a JBM level. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4186432#...
