Exception thrown at startup (default context)

I'm trying to move my app that uses SecurityFilter to our production
server and am suddenly running into some problems. It appears to be a
logging issue but I cannot figure out how to fix it. It ran just fine
on a dev machine, but now I'm moving it to a new box and making it the
default context. Trying to deploy on Tomcat 4.1.8 with log4j-1.2.7
installed in my WEB-APP/lib directory. The stack trace is:

2003-03-20 09:56:09 StandardContext[]: Starting filters

I see a similar question was posted a couple of months ago, but I
didn't see an answer.

Thanks for any help!!
