servlets get called by clients requests, they process them somehow and they
send back a response to the client who called them. so there is no way to
redirect the servlets response to some adressee or make a window pop up there.

a typical workaround for this behaviour is utilizing applets which reside in
each clients machine and which are responsible for communicating with your
servlet, that keeps track of the incoming massanges, updating clients data,...

a less sophisticated workaround might be to keep each client requesting the
servlet periodically and making the response trigger a pop-up if some new
message arrived.

there probably are a lot of (open source) chat applications out there, just
type servlet and chat and hit the google-search button.
