need help with first time setup of log4j

I have it working on my local server setup, but can't get it working on the Tomcat/Red Hat box. The log file is never created and nothing appears in catalina.out, which if I understand correctly, is where the console appender messages should appear. Please correct me if that's wrong.

The log4j.jar file is in the Tomcat /lib directory and the file is in mywebapp/WEB-INF/classes. Here is the properties file:

# map this appender as the root logger
# set the debugging on for testing the log4j setup

log4j.rootLogger=DEBUG, R, consoleAppender

# console appender
log4j.appender.consoleAppender.layout.ConversionPattern=%-5p %c{2} %x - %m%n

# file appender
log4j.appender.R.layout.ConversionPattern=%-5p %c{2} %x - %m%n

# set the maximum log file size
# archive log files (one backup file here)

I'm at a loss as to how to troubleshoot this any further. I've restarted the webapp and even restarted Tomcat with no change. There are no errors in catalina.out and no errors from the app when it hits the log.debug statements.

At this point I'm thinking about creating a simple, single page jsp test app that runs in it's own context to try and confirm that log4j is working, but I feel like I'm clutching at straws. Any tips? Am I correct that console appender messages should appear in catalina.out?

I agree. Here's the link:
