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
<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 On Fri, May 27, 2011 at 9:40 AM, Patrick Julien <[email protected]> wrote: > you can use websockets but not many browsers support it.
