To be honest, I'm not sure - try removing velocity.properties from
WEB-INF/classes - or removing the Velocity JARs altogether.

In log4j.properties, or log4j.xml - set it to WARN:

log4j.logger.net.sf.navigator=WARN

Not that I know of - have you tried removing Struts Menu (just view
source and copy the HTML into your code) and seeing if that helps?
