I'm trying to implement a websocket-server with Progress OpenEdge. I still didn't get it working.

I've successfully created a socket-server with the example i-sktsv1.p from here.

When I run my html-page, which looks like:

<!DOCTYPE html>
<html lang="en">
<meta charset="utf-8" />
<title>WebSocket Client</title>
<script language="javascript" type="text/javascript">
var wsUri = "ws://localhost:3333/";
var output;

function init() {
output = document.getElementById("output");
testWebSocket();
}

function testWebSocket() {
websocket = new WebSocket(wsUri);
websocket.onopen = function(evt) { onOpen(evt) };
// websocket.onclose = function(evt) { onClose(evt) };
websocket.onmessage = function(evt) { onMessage(evt) };
websocket.onerror = function(evt) { onError(evt) };
}

function onOpen(evt) {
writeToScreen("CONNECTED");
doSend("WebSocket rocks");
}

function onClose(evt) {
writeToScreen("DISCONNECTED");
}

function onMessage(evt) {
writeToScreen('<span style="color: blue;">RESPONSE: ' + evt.data+'</span>');
websocket.close();
}

function onError(evt) {
writeToScreen('<span style="color: red;">ERROR:</span> ' + evt.data);
}

function doSend(message) {
writeToScreen("SENT: " + message);
websocket.send(message);
}

function writeToScreen(message) {
var pre = document.createElement("p");
pre.style.wordWrap = "break-word";
pre.innerHTML = message;
output.appendChild(pre);
}

window.addEventListener("load", init, false);
</script>
<body>
<h2>WebSocket Test</h2>
<div id="output"></div>
</body>
</html>


I getting a error that the websocket connection could not be established.

The problem is (I think) that Progress offers a socket, not a websocket. Do you know how to get this working?
