    Default Embed JWebSocket to tomcat and test it

    Hi guys,

    I am trying since yesterday to embed JWebSocket into my
    webapps.

    Which Tomcat I am using?
    I user tomcat apache-tomcat-6.0.20

    What I`ve done until now?
    -I copied jWebSocketAppServer-0.9.0.war into the tomcat webapps file
    -I copied jWebSocketServer-Bundle-0.9.0.jar into the lib file of my webapp called "chat"

    What is the next step? I unfortunatly have no idea :(

    How can I find out, my JWebSocket works correctly?

    I have this code from a html5 book:

    XML Code: 
    <!DOCTYPE html>
<html>
<head>
	<title>Websocket</title>
	<script type="text/javascript" src="jquery-1.7.2.min.js"></script>
</head>
<body>

	<form action="#" id="chat_form" method = "post">
	
		<input id="msg">
		
		<input type="submit" value="senden">
	
	</form>

	<script>
		
		var websocket = new WebSocket('ws://localhost:8080/');
	
		websocket.onopen = function(event){
			$('#chat').append('<br> Connection...');
		}
		
		websocket.onmessage = function(event){
			$('#chat').append(event.data);
		}
		
		websocket.onclose = function(event){
			$('#chat').append("<br> closed");
		}
		
		$(function(){
			$('form#chat_form').submit(function(e){
				e.preventDefault();
				var textfield = $('#msg');
				websocket.send(textfield.val());
				textfield.val("");
			})
		});
		
	</script>
</body>
</html>
    Thanks in ahead for help.



    ***EDIT:
    Further I found out I need a class that implements ServletContextListener. But because I user Tomcat 7 in the past
    I cannot assign my projects tomcat 6 server. I need tomcat 6 server because jWebsocket isnt supported by Tomcat 7.
    In an website I read that I have to switch the Servlet API from 3.0 to 2.5. But how can I do this?

    Default Re: Embed JWebSocket to tomcat and test it

    Hmm, now I get a text in the console in chrome:

    "Error during WebSocket HandShake. Header is missing"

    What does this mean?
