Delegate the decision. I solved this by removing any direct reference to a
path and instead referenced a servlet in the document() function passing the
path as a parameter. The servlet becomes responsible for opening the
resource and passing the XML back in the HttpOutputStream. If the resource
cannot be found, the servlet returns a valid, but empty XML file.
