Hi, I am having a stateless session beans which makes database updates. At times the method may makes 500-600 updates serially. Sometimes i could see a warning message from in server log as below ---------- WARN [org.jboss.tm.TransactionImpl] Transaction TransactionImpl:XidImpl [FormatId=257, GlobalId=CASRVJM3142DT22//39, BranchQual=] timed out. status=STATUS_ACTIVE ----------------- But Jboss doesnt throw any exception and the update fails and there is no way i could catch the exception and do a appropriate action. Please help me with some kind of information as why this warning may apear and the ways to overcome this.
