PQ63531: EXCEPTION THROWN BY SESSION MANAGER WHEN AN OBJECT IS NOT SERIALIZABLE NEEDS TO BE MORE DESCRIPTIVE | |||||||||||||||||||||||||||||||||||||||
![]() |
|||||||||||||||||||||||||||||||||||||||
![]() APAR status Closed as program error. Error description If a WebModule is marked as "distributable" and persistent sessions are being used, all objects placed into the HTTPSession must be serializable. In DatabaseSessionData.class, we make a check for this. If the object is not serializable, we throw an IllegalArgumentException without any detail. To improve the serviceability of the Session Manager, we should print out the fact that the WebModule is distributable and that object "x" is not serializable.Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server - Session * * Manager Users * **************************************************************** * PROBLEM DESCRIPTION: Session Manager is not logging the * * name of non-serializable values in * * the standard log when the webapp has * * been defined as distributable. * **************************************************************** * RECOMMENDATION: * **************************************************************** As per J2EE spec a web module defined as distributale requires all the values bound into the session object to implement the serializable/externalizable interface. If a non-serializable value is bound into the session object the session manager currently logs an IllegalArguementException but doesn't record the value name in the standard logs which if done would be helpful to WebSphere users for diagnostic purposes.Problem conclusion This fix will make the session manager to log the value name of a non-serializable object in the standard output file.Temporary fix Comments
