Subject: Re: log4j wrapper
That's why you need to provide the fully-qualified classname. If you
use the wrapper I showed, you will not have this problem. That is, the
class and method name of the wrapper caller, not the wrapper itself,
will be logged. The code which determines the logging method looks one
past the fully-qualified classname in the callstack. Check it out, I
thought it was rather ingenious myself.
