Rather than using html requests (I only assume this because you're talking
about multipart and such things) I would suggest that you have the servlet
listening on a socket. Connect to that socket with the applet and then send
the files in and out with byte streams. As long as you're not behind a
firewall then this would be the best I think.
If you, or your projected users, are behind a firewall then you may have to
resort to HTML and do what the previous poster told you.
Hope this helps!
