  2. Click Choose File, browse for the PFHC_Core_731.jar file from your distribution media and import.

Root Cause

A defect or configuration issue in the operating environment.

Pega database contains an old version of xerces-2.4.0.jar that causes issues with Pega engine in trying to find implementation for DOMImplementationLS Class' abstract method createLSSerializer()/


Make the following change to the operating environment:

1. Run the following query to identify the row in table that contains the jar in customer pzcodeset:

select * from <pegarules_schema>.pr_engineclasses where pzclass like '%DOMImplementationLS%'

2. Delete the row from the database table and restart the JVM.
3. Follow the import instructions from upgrade guide.
