If I understand correctly, if you want to use your extended classes you'll
have to _replace_ the original log4j classes, not extend them. That's the
only way the app code will call your custom code when initializing a logger.
Isn't it possible to achieve your goals with custom Appenders and Layouts
only? Since appenders and layouts can be specified in the config files, that
would be the only way, IMHO, you can do this without messing with the app
code (which you don't have access to)
cheers,
