Hi Wyn
Yes, that's what I'm trying to do. My problem is that the uri is not fixed;
it could belong to any of the other web apps, including the default /
handler. Now getContext() gets the right ServletContext fine, but to then
get a RequestDispatcher, I need to strip off the context root part of the
URI, and I don't know what that is! In the exanple here, it is "/app2" but
for the root context it would be just "/". What I need is a ServletContext
method which returns the context string, but I don't think such a method
exists.
