Why do you use commons-logging in your application classes?  I can see a 
semi-legitimate argument for a framework doing this, so as to not force a 
particular logging implementation on the user.   However, you are the 
user.  You choose the logging implementation.  You have, obviously, chosen 
Log4j as your implementation of choice.  Why not cut out the middle man 
(commons-logging) and use Log4j?
