In short not really. If you create this logger from programmatically 
(from Java) then yes. Have a look at my ServletAppender on Bodington 
HEAD that I setup from the context listener.

Logging to a directory inside the webapp isn't a "good thing" as in some 
situations you may not be able to write there. Also when an upgrade is 
done you will lose your logs so beware.
