I have a question about the Communication between a client and a server.

I would like to create a GWT application that can do the following:

The client A fires an event to the server and the server in his turn fire an event to the client B.
Here the client B has to be able to listen to the event all the time.

I wanted to send some event with few data in real time to a connected client B.
is that possible? and if yes how can I do that?

Thanks

    Here the client B has to be able to listen to the event all the time.

    To let client wait for data, you can use Comet [1] (long lived HTTP requests) or WebSockets [2] if targetted JS runtime does support it.
