The browser repaints the page after nearlly every request, the only
server response (that I am aware of) that doesn't cause a page repaint
is NOT_MODIFIED.

tricky...
This is not really a problem with servlets... it's a general web
architecture thing. The web is designed around batch dispatch of
interaction data (eg: forms) not live update (like you might have in
an old client-server type app).
It sounds to me like you should redesign your system to take heed of
this.

This is really not how servlets are used. But you could use an applet
on the web page to talk to a servlet (or any other kind of server type
thing, eg: CORBA) and that would give you a little more
flexibility....
But as I say, usually when people ask these questions (IMHO) it's
because they've got the design wrong, change the design to fit in with
web architecture and everything gets better.
