How to configure logging

[Jim Graf]

Hi,

I need to trace my webapp (a combination of myfaces and adf) and I found 
this:

http://wiki.apache.org/myfaces/LoggingSettings

but as I've never used commons-logging or log4j, I have no idea of how 
or where to configure that information. I'm using tomcat 5.0.x and I'm 
not using any IDE.

I would appreciate any information or example.

thanks,
jim
