Hi Patrick,

thanks for the help.

I am now trying to use websocket and there is only one example i cn find online.

http://code.google.com/p/gwt-comet/wiki/WebSockets

I do not understand one thing.

websocket connects to some port.But where is the code to receive the connection.

I do not think this is complete code.

Do you not think we would always get onClose() call back.

Is there  a  complete example where I can look at client server communication using socket in GWT.

thanks

Hamish

you can use websockets but not many browsers support it.  You can use comet
