Js:

    Wiki Project 
    window.addEventListener("load", onLoad, false);
       
        function onLoad()
        {
            var ws\_address = "ws://0.0.0.0:8090"; 
            var socket = new WebSocket(ws\_address);
                            
            socket.onopen = function(event) {onOpen(event);};
            socket.onclose = function(event) {onClose(event);};
            socket.onmessage = function(event) {onMessage(event);};
        }
        
        function onOpen(event)
        {
            alert("OPEN Connection");
        }   
        
        function onClose(event)
        {
            alert("CLOSE Connection");
        }
        
        function onMessage(event)
        {     
            alert(event.data.toString()); 
        }      
        
        function insertMessage()
        {      
            socket.send(document.directing.message.value);
            document.directing.message.value = "";
        }      
        
        function viewMessages()
        {            
            socket.send("@View@");  
        }         

        function deleteMessage()
        {         
            socket.send("@Delete@");
        }

You are trying to send to an invalid address.

[Mr_z]

How do I write this?
I need them both to listen to Port 8090

[Lost User]

The port number is fine, but you are using the IP address 0.0.0.0.

[Mr_z]

i use

var ws_address = "ws://" + document.location.host + document.location.pathname + ":8089";

not work

Try connecting to the server code through a browser to see if it will accept a normal request. I do not know Vertx so you may need to use their support lines for help.
