Use MDC for the string? ■ DOUGLAS E. WEGSCHEID // LEAD ENGINEER (269) 923-5278 // douglas_e_wegsch...@whirlpool.com "A wrong note played hesitatingly is a wrong note. A wrong note played with conviction is interpretation."

I've found that when I do this I can't use properties to filter the log level, such as log4j.logger.ca.something.package=INFO I figure this is because if I use getLogger(Device.class) it gets the package of the logger from the class I give it and it all works from there. So this all makes sense, but brings up two questions: Can I still declare my loggers with a String name (getLogger(String)) and somehow still use package-style log level selection in the properties file? If not, do you guys have any tips on how to differentiate between instances when they're logging? The obvious solution would be to prepend any log message I want to write with a description of the instance, but that seems like a lot of extra work. I think really what I'm looking for is something like getLogger(Class theClass, String theName), but maybe there is an already-implemented way to do this. Any tips?
