![]() APAR status Closed as program error. Error description Following a transaction rollback, a false crossover message was reported by DebugSessionCrossover property.Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server Version 5.1.1 * * users of sessions. * **************************************************************** * PROBLEM DESCRIPTION: A session crossover detection warning * * can occur if the WebContainer throws * * an exception. * **************************************************************** * RECOMMENDATION: * **************************************************************** If a TransactionRolledbackException occurs while the WebContainer is processing a post invoke a counter the session uses will fail to be properly decremented. This can result in a session crossover detection warning. Below is an example of the type of exception that can be thrown: HttpForwardViewCommandImpl forwardDocument CMN1244E: An error occurred when forwarding document /PostalStore/ShoppingArea/ CatalogSection/SearchSubsection/CatalogSearchResultDisplay.jsp. javax.servlet.ServletException: GlobalTransaction rolled-back due to timeout or setRollbackOnly javax.servlet.ServletException: GlobalTransaction rolled-back due to timeout or setRollbackOnly at com.ibm.ws.webcontainer.webapp.WebAppTransactionCollaborator. postInvoke(WebAppTransactionCollaborator.java:226) at com.ibm.ws.webcontainer.webapp.WebAppRequestDispatcher. dispatch(WebAppRequestDispatcher.java:695) at com.ibm.ws.webcontainer.webapp.WebAppRequestDispatcher. forward(WebAppRequestDispatcher.java:208)Problem conclusion The WebContainer code was modified to wrap the calls in a try/catch/finally block so the sessionPostInvoke method will be called regardless of an exception occurring. The fix for this APAR is currently targeted for inclusion in fixpack 5.1.1.14.
