Some parts of Tomcat do use Log4j, other parts do not. I think this is because different people have just chosen whatever they felt was handy. Tomcat doesn't yet have a unified logging strategy. I originally tried to use "commons-logging" as my back-end and it can be configured to use Log4j, but as I described - the result was unsatisfying.
