Steps to Reproduce



Deploy prsysmgmt.war file. Try to execute stop/start/isalive or any other commands.

Root Cause



The prweb.war which is shipped with the product  has commons-logging.jar included, but in customer environment  another commons-logging.jar  exists in  the apache tomcat lib.This duplicates the one which is present in the prweb.war and is the root cause.


Resolution




Remove the commons-logging.jar from their apache tomcat  /lib directory tomcat.
After re-deploying the prsysmgmt.war works fine.
