Tomcat uses commons-logging for its logging needs. Apache commons
logging does decide what logging implementation to use at the time
when a class is loaded. If log4j is reachable through the current
thread classloader, it will be used. And the first time log4j is
accessed, it configures itself. In this case it searches for
log4j.properties or log4j.xml in your app's classes folder or
somewhere else from where classes are loaded.

Yes. You may want to dig into commons logging for more details.

May be. I do not have experience of reconfiguring log4j on the fly.
