A Null Pointer Exception occurs with the result handler for an SCA invocation for WebSphere Process Server (WPS)

Technote (troubleshooting)


Problem(Abstract)

After you successfully upgrade to WebSphere Process Server Version 7.0.0 Fix Pack 4 (7.0.0.4), you receive a null pointer exception on the result handler for the Service Component Architecture (SCA) invocation while processing an application in the Business Space.

Symptom

The null pointer exception is thrown and the "EnrollmentException" process starts after the "Drop to paper" from your Java™ custom snippet. The Trace file and the SystemOut shows the following exceptions:

Cause

This issue results from duplicate plugin Java archive (JAR) files that are generated by the upgrade process.

Resolving the problem
