I guess you could write a custom OutputStream subclass for the System.out in 
your non-servlet classes that would interface with the layer that connects 
those classes to the webapp and specifically with Logger instances.

However, I think this approach would violate the KISS rule and attract the 
wrath of future generations of programmers (or your colleagues).

It's really easier to replace System.out.print() with commons-logging calls 
judging from the information you supplied but it's your call.
