Abstract
Corrupt WorkArea contest in a loop-back Scenario
 
Download Description
ERROR DESCRIPTION:
An issue has been found where WorkArea context is incorrect in an application that consists of a loop-back scenario. A loop-back consists of one application in a server (server1) calling another application in a second server (server2). The second application then calls back to the first. This throws a null pointer exception indicting there is no WorkArea context.
This occurs in WebSphere® Application Server Enterprise Edition 5.0 and 5.0.1.

PROBLEM SUMMARY:
A NullPointerException is encountered in a loopback scenario whereby an application (using WorkArea) makes a remote call to another application and in turn that application calls back to the originating (first) application.

RECOMMENDATION:
A NullPointerException is encountered in a loopback scenario whereby an application (using WorkArea) makes a remote call to another application and in turn that application calls back to the originating (first) application. Invalid WorkArea context in a loopback scenaro. WorkArea context will remain after completiong of the loopback scenario. When the remote call finished and control returns to the first application, the WorkArea context owned by that app is lost. This results in a NullPointerException when the user tries to access the context in the WorkArea. The reason for the NPE is that since the context got lost after the loopback scenario, the WorkArea points to a null object.
