logging.properties shouldn't matter here.

The key is to make sure that log4j uses the log4j.properties or log4j.xml
for your application.

I'm not familiar with the classpath setup in Tomcat 6, but there's often a
global / server / shared / system classpath, and then an application
specific classpath with its own classloader.

Did you put log4j jar in WEB-INF/lib/ ? and log4j.properties/xml in
WEB-INF/classes/ ?

You can always either:

   - Step through the log4j initialization code with a debugger
   - Programatically modify the log4j configuration
   - Turn on debugging -Dlog4j.debug (see for example
   http://stackoverflow.com/questions/1140358/how-to-initialize-log4j-properly
   )

Did you read the Tomcat specific section here
http://logging.apache.org/log4j/1.2/manual.html ?
