Chris,
I'm not sure I understand what you are doing exactly. You've mentioned that
you put a copy of the default web.xml file in your application directory,
but you have mentioned that you edited the file to reflect your
application, so I'm beginning to guess that you haven't done that. If you
haven't already done this, read Chapter 13 of the Servlet specification
(http://java.sun.com/products/servlet ) to get an idea of what the
different elements are used for. I'm by no means an expert on this, but the
web.xml file is the "deployment descriptor" of a web application - if you
put one in your application's directory structure, you need to edit it to
provide the information that's specific to your application. The default
web.xml file isn't going to help you in your application deployment because
it has information specific to the servlet container itself. You might take
something like the web.xml file from the examples directory and edit it to
represent your specific web app. If the web.xml file doesn't describe the
specific application, it doesn't really have any point to being there. Hope
this helps.
