Hi Dennis,
Followings are information and recommendation from me.
These are based on short examination with default settings of Tomat-5.5.12.
But, please note that behavior of a servlet named "default" might
be different for each container and its configuration.

I think it's hard to test the forwarding by using Cactus
as long as you are using getNamedDispatcher("default").
RequestDispatcherWrapper#forward(), which is used in the test,
calls the original RequestDispatcher with the original HTTP request.
# See Cactus API JavaDoc.
A servier-side test case is invoked from a servlet,
/<context>/ ServletRedirecter. So, the request URI of the original HTTP
request is "/<context>/ServletRedirector".
When the original RequestDispatcher is the default servlet of Tomcat,
it's trying to obtain the resource from "/<context>/ServletRedirector",
that has the possiblity of causing an infinite loop.
# Fortunately, the default servlet responds 404 and stops the loop.
Please try following fragments of servlet and web.xml.
You will find similar behavior with your Cactus tests
when you access to <context>/dummy.
public DummyServlet
extends HttpServlet
{
protected void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
getServletContext().getNamedDispatcher("default").forward(request,
response);
}
}
<servlet>
<servlet-name>dummy</servlet-name>
<servlet-class>DummyServlet</servlet-name>
</servlet>
<servlet-mapping>
<servlet-name>dummy</servlet-name>
<url-pattern>/dummy</url-pattern>
</servlet-mapping>
I would like to recommend you to use getRequestDispatcher(String)
instead of getNamedDispatcher("default"), it it's possible.
If you can do so, you will be able to simulate any path condition
for a testXXX() by using org.apache.cactus.WebRequest#setURL() method
in beginXXX(), and you can evaluate a forwarded responce in the corresponding
endXXX() method.
# You should not simulate <context>/ServletRedirector,
# which is the default of Cactus, of cource :-)
Hope this helps,
