CiscoWorks Tomcat Servlet Engine service does not start , Windows Version
Problem :-
My Tomcat Servlet Engine Services unable to Start due to my previous regdaemon.xml was empty and i dont why.
Solution:-
What I do, is I look for a filename " regdaemon "
As for me it located at C:\Program Files\CSCOpx\MDC\etc
I copy paste the old script of regdaemon.xml.bak and put inside regdaemon.xml and save.
After that I try to restart the CiscoWorks Tomcat Servlet Engine services and it works..!
