I don't recall what the BasicConfigurator does. You are making an assumption
that it creates a Console appender and sets this on the root logger. Don't
make assumptions. Don't configure anything manually. Just put
log4j.properties in WEB-INF/classes and point your File Appender to some other
file than what Tomcat logs to and see if you get the output you expect. If you
don't try this, there's nothing else I can do to help.
