Howdy,
RTFM:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.htm=
l

Or search the archives.

WEB-INF/classes is automatically on the "classpath" for your webapp an=
d
JSP.  You don't need to modify the classpath environment variable nor
any of the classpaths in tomcat's startup scripts.
