We're using Log4J in a medium-sized Webapp, along with Struts and other
stuff.
I defined a "Logger" Facade that isolates the code base from Log4J; were we
to ever switch logging packages, it'd be a snap. Basically it calls through
to the Category methods. The Facade does the initialization also. BTW if you
can use the XML configuration format, by all means do, it's much easier to
set up and maintain than the property file.
At the top of each action class we have:
private static final Logger log = Logger.getInstance(MyAction.class);
then we do:
log.warn("some harmless error occurred", exception);
It's very much the same thing.
