Unable to import Issuer\SmartDisputeBase_Schema_07.22.jar



Unable to import the Issuer\SmartDisputeBase_Schema_07.22.jar which is a part of the HFix-45800 (Skim Patch to 7-22-XX) and SQL DDL generation error occurs. The import is performed on an existing application running on Pega Smart Dispute (SD) 7.21.

Error Messages

Error Message: Was unable to extract metadata definition for database object 'pc_assign_worklist'

Log file error message: An error occured generating table XML for table sd_dispute: code: <none> SQLState: org.apache.xml.serializer.ToXMLSAXHandler cannot be cast to org.apache.xml.serializer.SerializationHandler Message: <none>
DatabaseException caused by prior exception: org.apache.xml.serializer.utils.WrappedRuntimeException: org.apache.xml.serializer.ToXMLSAXHandler cannot be cast to org.apache.xml.serializer.SerializationHandler

Steps to Reproduce

  1. In an existing application running on SD 7.21, install hotfixes upto HFix-45382.
  2. Import the Issuer\SmartDisputeBase_Schema_07.22.jar.

Root Cause

The org.apache.xml.serializer.ToXMLSAXHandler class is resolved from the oauth.client.jar-0.0.1-SNAPSHOT.jar instead of the serializer-2.7.1.redhat-7.jar which is shipped with JBOSS. The oauth JAR file was a third-party JAR file used for the application functionalities causing a conflict. Hence, serialization fails while importing the schema change JAR files.


Perform the following local-change:
  1. In module.xml where the oauth JAR lies within the JBOSS file system, comment out the resource-root section for the oauth.client.jar-0.0.1-SNAPSHOT.jar.
  2. Restart JBOSS.
  3. Reimport the Issuer\SmartDisputeBase_Schema_07.22.jar.
