Hi, I think it is not possible without polling, because if the users are behind proxy servers, then even if the server gets the remote addresses by means of getRemoteAddr() or some other method, this address will only be that of the proxy server and not the actual m/cs themselves. I think to tunnel it thro' firewall the best thing to do with a polling scheme is to connect to the servlet using a URLConnection object and read/write using a ServletOutputStream. Not sure.. but looks feasible. Regards, Partha

It talks to server via Applet to Servlet Communication. There is one application running at the server side, which processes some order. Now the functionality which I have to build is that the application should be able to push orders to the applets, so that the users who are currently watching the applet should be able to see the latest data automatically without sendinga request. I searched on web but couldn't find anything as to how can I push data to all the connected applets of the site. The solution which I thought is the applet will poll the server after every say 1 minute to check if there is any new to show. But suppose the number of user is more and there is nothing new to show, the applets will unnecessary making the request to the server. I can't use Socket connection or RMI as the site will browsed outside the firewall. Is there any way by which I can push data from server to applets, so that when ever new thing will come server will make connection with applets and push data thereby using network only when needed. Unlike in polling the network is used unnecessarily.
