What's the quickest and easiest way of my code knowing what class called a method? The reason I ask is because we have some wrapper methods in our main class that every other class calls to do logging. I would like that method to be able to determine what class it was that called, so that I could use the proper logger/category.
Also, for log4j, is Logger.getLogger("classname") an efficient way of getting a logger for each class? e.g. should I be calling this method every time my *wrapper* log method is called? How does the commons logging do this properly, surely it has to do something similar since it's a wrapper too?

I thought I read somewhere that JCL allows one to turn on/off debug logging based on the package or class name. Is that right? I'm looking on the JCL website, but can't find information on that. Perhaps that's because I don't know what to search for!
JCL is simply a "wrapper" that provides a common API to a number of different logging libraries. Configuration of the underlying library is explicitly *not* part of JCL.
So if you are using log4j as the underlying library then you need to read up on how to configure log4j to turn on/off logging by category name. If you are using native jdk-1.4 logging as the underlying logging library then you need to read up on configuring that, etc.
Both of the above logging systems *do* have the ability to filter log messages based on log category name (and the recommended convention is for code to use the current class name as the log category).
