HttpServletRequest::getParameter generally doesn't read into multipart/
form-data (only application/x-www-form-urlencoded AFAIK, and it's
actually not explicitly spec'd in the Servlet API, just one
interpretation of the spec); you'll have to use something like Apache
Commons Upload to parse the multipart/form-data request payload.
