I made a WebSocketServletContextListener implementing
ServletContextListener.
And in this class, I started a jetty server which had a WebSocketHandler
set DefaultHandler.
I register this class as a listener in web.xml.
Client ia a chrome 16.0.912.63 m.
On client,
var location = "ws://localhost:8081";
this._ws = new WebSocket(location);
Is this problem why client and server's websocket version is different ?
I don't know what jetty's websocket version is.
As I know chrome v.16 supports Hybi17..
I don't know what I would do....-.-;;
I wish you have an answer or hint..
Thank you all for reading..
and thank you so much for your answer in advance..
Happy Christmas ~ ^_____^
