how to use log4j within struts

[Step <sh...@pd.jaring.my>]

I want to use the common-logger from Jakarta and uses log4j. 
 
1.      Does anyone have a sample log4j properties/initialization file
that they would post so that I could take a look?
2.       how to set up the logger in my struts application.. for
instance my action class.
 
Thanks
