java error on startup

I just installed tomcat 4.1.24 (RPM) on my linux box (sun jdk/sdk
1.4.1_02) but it doesn't start. I just get this in the log:

Tomcat 4.0.4 ran just fine on the same box. Any suggestions?

Check that you don;t have conflicting commons-logging jars  (or other jars) 
in your webapp and common/lib
