Websocket JSR 356 sample implementation on tomcat 7.0.52

[ninad patil]

I have a simple websocket application which I have deployed on tomcat 7.0.52. I am using JSR 356 API javax.websocket-api-1.0-b08.jar.

My Java server side code is

import javax.websocket.server.ServerEndpoint;
import javax.websocket.*;

@ServerEndpoint("/hello")
public class HelloBean {


@OnMessage
public String sayHello(String name)
{
return name + "return";
}
}
Whenever i try to connect to websocket it throws me error that its close.

On Client end (javascript) : Code is as follows

var ws = new WebSocket("ws://localhost:8080/hello");

ws.onopen = function()
{
ws.send("Message to send");
};
ws.onmessage = function (evt)
{ // var received_msg = evt.data;
alert("Message is received...");
};
ws.onclose = function()
{
// websocket is closed.
alert("Connection is closed...");
};
I am not able to understand why it is showing connection is closed message.

Help on this will be much appreciated.

Thanks
NP

Is the HelloBean class deployed in the ROOT web app? Only in that case would localhost:8080/hello be the correct URL. What happens if you go to http://localhost:8080/hello in your browser?
