Excellent, tried running that JSP and it revealed the true error:
A missing jar file on the deployment box. The jar is expected in
tomcat/common/lib directory.
I've added it to my application lib directory and the problem has
disappeared.
Thanks for your help
Robin

Subject: Re: ActionServlet failing to load
Date: Sun, 17 Jul 2005 12:18:14 -0400 (EDT)
Is there any chance struts.jar is simply not in the classpath?
The stack trace seems to indicate your not even getting into Struts code,
so its I think either (a) not finding the ActionServlet class or (b)
failing during construction. The first seems far more likely.
I suppose an easy way to test would be to remove the ActionServlet entry
from web.xml, then just have a simple JSP that tries to dynamically load
the class...
<%@ page language="java" import="org.apache.struts.action.*" %>
<%
try {
Class clazz = Class.forName("org.apache.struts.action.ActionServlet");
ActionServlet as = (ActionServlet)clazz.newInstance();
} catch (Exception e) {
e.printStackTrace();
}
%>
...and see if you get an exception... Looking at the ActionServlet source
for 1.2.6, unless I'm missing something, it's just using the default
constructor, so I very much doubt its a construction problem.
