How to configure in Webmethods Integration Service a "customize logfile"

Hello,
could you help me to find out how to configure a customise log file for same services ?
The cusomise logfile should me contains only business information from a special java service.
I know how to use the Build-In logging methods and functionalities. But i couldn’t find out how to write the customise log information to a own logfile like accounts.log.
Could you give me same information how to do this on IS side ?

Thanks

This has been implemented previously and was part of the wmusers shareware. I think the functionality you ask is currently residing at below location.

This code helps integrate the Apache log4j functionality with webMethods.
