problem loading class for STRUTS

I am trying to install a struts example using Tomcat 4.1 which was installed as part of Sun One Studio which I using for development. I am using the xerces XML parser, have xerces.jar loaded into the class path. I also have struts.jar and the default WAR files loaded into the path. I get an error loading this class
web/index.jsp [2:0] Unable to load class org.apache.struts.taglib.html.HtmlTag
Thanks for the help,
Dinesh

Tomcat can be particular about where the jar files are located. If they're in the 'system classpath', that is usually not good enough.
