1) rollback the branch and ignore it (i.e. return XAERR_NOTA) or don't roll it back at all. In this case setTransactionTimeout MUST return false to indicate that the timeout is not handle as expected by the resource 2) setTransactionTimeout returns true and this implies that the branch is rolled back and XA_RBTIMEOUT is returned. I.e. we must remember the tx branch ID. Arnaud View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4186384#...
