Please try getting rid of the initialization servlet and calling your config
file log4j.properties and put it in WEB-INF/classes (with log4j.jar in
WEB-INF/lib, of course). You're making this overcomplicated. First, get it
working with a base-minimum setup. You can add complexity after get your
bearings.
Also, I suggest logging to a different file than what Tomcat logs to.
