If you call Category.getInstance() with the same class/string name, you'll get the same category. The examples are simply caching the result since there is a hashing performance hit for calling Category.getInstance() repeatedly for the same category. > Now, as I also understand it, when a class is first referenced, its > static var's are instantiated at that time.

Until log4j is initialized you can't do any logging anyway.

The best way to evaluate log4j is to try it out. Go ahead download it, create the scenario you've just described and make sure it works as you expect. If you have problems then, we'll be better able to help you out. -- Don __________________________________________________ Do You Yahoo!? Make a great connection at Yahoo!
