The book Java Servlet Programming has a great example of Applet to Servlet HTTP communication and the code examples are online at http://www.servlets.com. Check out this link for the Applet to Servlet chapter examples: http://www.servlets.com/jservlet2/examples/ch10/index.html Remember, if you want to use the classes in the book, you need to own a copy according to the license agreement.

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.
