I can't find org.apache.catalina.loader.Reloader in any jar that comes with Tomcat4

[Alexander Höglind]

This error is from within Visual Café 4.1 trying to debug servlets with 
org.apache.catalina.startup.Catalina as Main class:
java.lang.NoClassDefFoundError: org.apache.catalina.loader.Reloader

I've included all jar files found in tomcat/lib, tomcat/common/lib, tomcat/server/lib 
in Project-->Directory. 
Any ideas?
