No, believe it or not, passing a subdirectory path to a CGI (where the
path extends beyond the CGI name) is some kind of standard, certainly
supported by Apache and several other servers, though rarely used in
anger. I am not aware that servlets actively support that kind of
mechanism, so the getRequestURI you suggest below would probably be the
only way of doing it (assuming JServ doesn't choke on the URI).

This will generate a "normal" URLencoded querystring, c.f.
<A HREF="/servlets/HelloWorld?I=want">click here</A>
which is different to what the original poster was trying to do, though
I would argue yours is the *right* way to do it :-)

To the original poster - quiz the user carefully to find out why they
(think that they) need to use the subdirectory-style URI's and you will
probably find out that they don't. Then tell them to use querystrings
(i.e. METHOD=GET) or POST-ed data and parse it with the normal servlet
API's like any other sane person ;-)
