In that case it's a bug in JRun. Even if they today (in their 2.1 compliant
servlet container) use a regular HTTP parameter to send the session ID,
encodeURL() should encode the URL according to their conventions, i.e.
something like
/servlet/foo?jrunsessionid=1234
And they should be able to handle a POST with both a query string and parameters
passed in the POST body. Merging query string and body params has been in the
Servlet spec since 2.1 I believe. If they handle this right, the original problem
(with POST parameters not being available with request.getParameter()) when doing
a file upload would be solved as well, since the query string parameter is available
even with a multipart request.

PS.It's probably better to bring this discussion to a JRun forum, since it
seems like it's a product specific problem.
