When I started Tomcat, I received exception saying "ClassNotFoundException: org.apache.catalina.mbeans.ServerLifecycleListener".

I reviewed the FAQ here and realized I got the exact symptoms as mentioned in the following page:

I have double checked the JAVA_HOME and CATALINA_HOME environment variables in my Win2000 pro and they look right to me.

My environment is Apache2.0.43, Tomcat4.1.18LE and J2SDK1.4

Any suggestion is appreciated!
