Play-Push is a project mainly written in OBJECTIVE-J and JAVASCRIPT, it's free.
A demo app that shows how to use Cappuccino and the Play! Framework to create a simple chat.
This is a demo application that realizes a simple chat system using the Cappuccino Framework (http://www.cappuccino.org) as the client and the Play! Framework. (http://www.playframework.org) as the server. The client will request new messages from the server using an AJAX connection, while the server will suspend that connection for a second each time it can't deliver new messages. This will keep the connection open as long as there are no new messages. Upon receipt of new messages, the connection will close and the client will reopen another connection to wait for even more messages, and so on.
This application is based on Elias Klughammer's explorations of Cappuccino, Tornado and Juggernaut, which he published here: http://github.com/eliasklughammer/Cappuccino-X-Tornado and here: http://github.com/eliasklughammer/Cappuccino-X-Juggernaut
He also published a video demoing his app, which should be pretty similar to Play Push: http://www.youtube.com/watch?v=1MPTxS9uyT4
Thanks a lot for sharing, Elias!
