How to initialize the log4j system properly?

[Desiree Anson]

When I try to run the startServer.exe, I get errors. 
log4j: ERROR could not parse url [file:/C://Program Files//CA//WorkloadAutomation_R11.3_SP3//conf//server.log4j.xml].
java.lang.NullPointerException
...
log4j: WARN No appenders count be found for logger (essential).
log4j: WARN Please initialize the log4j system properly.

What do I need to do this, how do I do it, and where do I do this?  Assume I know nothing about java...

Thank you

Nevermind!  I had it set accidentally in the PATH variable.  I removed it and this works fine now.
