read the Log4j manual that discusses how to do this properly. You'll note in the book it states to NOT extend Logger. Use the wrapper pattern (wrap through aggregation). The book discusses how. There's a PDF version available too. Mike PS What you're doing is very common.
-----Original Message----- From: Fabrizio Squittieri [mailto:[EMAIL PROTECTED] Sent: Thursday, June 23, 2005 3:34 AM To: log4j-user@logging.apache.org Subject: Creating our own logger Hi there, we have an old logger, an "homemade" one and now we want to switch our logging to log4j. We have to cope with the old one for the future as all the model software written until now can't be rewritten to suite the old log. Moreover we want a more powerful Logger class, as we must hold infos as userAddress userName and so on. In this scenario i thought to extend log4j and create my own Logger class, in this way i can use all the log4j features and specialize behaviour as we want. I would like to have a common interface as i can see this new Logger by this interface in my new model software where it arrives after been created by a servlet (which will be responsible of setting extra infos) whilst for the old software can be seen as the old logger. So it would be Logging interface (which?) Old logger ^ ^ | | My new Logger But the point is that i can't see any interface implemented by log4j as i hoped... In fact i tuought it would have been a Logging interface implemented by log4j and java.util.working... That's not truth unfortunately. What do you suggest?
