This week's giveaway is in the Java/Jakarta EE forum. We're giving away four copies of Java EE 8 High Performance and have Romain Manni-Bucau on-line! See Java Servlet Programming. Any help is welcomed and will be appreciated. Thanks everyone ! Bye.
That's the problem with http-based applications. It's a connectionless protocol. You're right, I do not think there is any way to do it via server-side push via http (well there is, that book shows a server-side push but it'll spawn lots of threads). So in the end, most http-based apps are client-polling apps. I looked at Sun's JSDT (shared data something) and maybe that's the solution but it seemed too complicated for me!
