Unable to perform rule comparision on pega 7.1.7



An error occurs when user runs the Rulebase Compare Wizard and enters the target system details.

Error Messages

The Flow Action post-processing activity VerifyTargetSystem failed: java.lang.NoClassDefFoundError: Could not initialize class com.pega.pegarules.integration.engine.internal.util.PRServiceUtilsPriv

Steps to Reproduce

1. Run the Rulebase Compare wizard.
2. Enter the target system details, and proceed to the next step.

Root Cause

PRServiceUitlsPriv fails while it is trying to load class. It is because MQMessage class is in class path (from mq-6.0.jar) but not its dependents. There will not be any problem if there is no class in classpath. But the failure is NoClassDefFoundError is not handled. Therefore, the existing mq.jars must be removed.


Perform the following local-change:
Remove the mq.jar file from the classpath and run the Wizard.
