That's a simple one ... "http://........." is a valid URL, not a pathname in
the local file system. A pathname would be something you could pass to the
file I/O routines and open.
If you want to do the translation that you've described, use getResource() to
get a URL instead of calling getRealPath() to get a pathname. Then, you can
open a URLConnection to read the content of the resource, or let the servlet
engine do it for you by calling:
InputStream is =
getServletContext().getResourceAsStream("servlet/ServletName");
and then read from the input stream. This will work whether the doc base is
set to a directory or an HTTP URL.
