Hi!
Probably you cant keep ObjectStreams indefinitely open, because
each one (for each new request from applet) needs a
thread on servlet engine. And other resources - request/response pairs,
and so on.
Other servlet engines might implement timeout policies
(e.g. closing requests/responses and associated threads
when "nothing happens" on their output stream)
It's better let the applet periodically ask for the object,
and the servlet can answer with an unchanged status code if the
object to be sent did not changed, without re-sending the object -
just to spare cpu/network resources.
not very helpfull..
