Re: GWT client server communication

Hi Ganesan,

Is there a way in GWT to push data from server to client.

Right now i am using RPC asyncallback but for that client needs to make request to server and then it responds.

So its more like pull mechanism .I wud need push .

Thanks 

Hamish

You can replicate the  TCP client server communication in your
