java - Unable to connect via websocket connection -

i'm trying create simple websocket connection in project.

java code:

@serverendpoint("/echo") public class echoendpoint { @onmessage public void onmessage(session session,string message){     try{         system.out.println(message);     }     catch(exception e){         system.out.println(e.getmessage());     } }  } 

html , javascript code:

<button type="button" onclick="websockettest()">send</button> <script type="text/javascript"> function websockettest() {   alert("websocket supported browser!");  // let open web socket  var ws = new websocket("ws://localhost:8080/echo");  ws.onopen = function()  {     // web socket connected, send data using send()     ws.send("message send");     alert("message sent...");  };  ws.onmessage = function (evt)   {      var received_msg = evt.data;     alert("message received...");  };  ws.onclose = function()  {      // websocket closed.     alert("connection closed...");   };    }  </script> 

after pressing button got errorwebsocket connection 'ws://localhost:8080/echo' failed: error during websocket handshake: unexpected response code: 404

jboss wildfly8 used application server.

any idea? or working example?

this because put wrong path here:

var ws = new websocket("ws://localhost:8080/echo");

if application packed eg: websocketapp.war (or if set context-path on websocketapp) should use:

var ws = new websocket("ws://localhost:8080/websocketapp/echo");
