Hi Joe,
The Velocity View Servlet calls getServletPath() and getPathInfo() on
the request to obtain path information for the current template, which
is then passed to a resource loader.
i.e.
a request "GET /index.html" to a VVS mapped to "*.html" will result in
the path "/index.html" being passed to the resource loader
a request "GET /" to a VVS mapped to "*.html" will result in the path
"/[welcome-file-name.html]" being passed to the resource loader (if
welcome-file is configured to be a .html file), but _only_ because the
servlet container will insert the welcome file name for you.
if you map in web.xml to "/whatever/*", everything after "/whatever/"
will be treated as path info, and the servlet container will not
interfere by appending welcome file names etc to ambiguous requests.
Therefore, a request for "GET /velocity/" to a VVS mapped to
"/velocity/*" will result an unresolveable path being supplied to the
resource loader (either empty string, "/", or null - can't remember
which) ... which will cause the ResourceNotFoundException.
The problem can be worked around by implementing a simple
"PathInfoResourceLoader" which looks for ambiguous template paths (e.g.
"/") then picks up the configured welcome-file(s) from the context and
appends them as necessary in order to resolve the request to a template.
... as for the other problem with velocity templates being picked up on
any requests, even when the VVS is mapped to "/velocity/*" - well, I
simply do not see how that could happen! Are you sure that is the case?
