|||||||||||||||||||||||||||||||||||||||
![]() APAR status Closed as program error. Error description Customer sees a javax.naming.NamingException. Root exception is java.lang.NullPointerException at WAS 4.0.3 and 4.0.4 when a HTTP Session times out. This happens when using the local name space, does not occur with global namespace.Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server -- Session * * Manager Users * **************************************************************** * PROBLEM DESCRIPTION: Session Invalidation fails when the * * valueUnbound method of an object bound * * into the session object uses * * environment references to access an * * actual resource. * **************************************************************** * RECOMMENDATION: * **************************************************************** The Invalidation Thread as part of listener processing invokes the valueUnbound method on each of the sessions implementing the HttpSessionBinding Listener. If the valueUnbound method uses environment references to access actual resources the namingspace collaborator for that webmodule in which the session is located needs to be associated with the session invalidation thread. This was not being done leading to naming exceptions being thrown when the lookup was performed in the valueUnbound method during listener processing.Problem conclusion This fix causes the NamingSpaceCollaborator for a web module to be attached to the Invalidation Thread before it starts invalidating the sessions for that web module.Temporary fix PQ66156.jarComments
