I have wrote my websocket server class and wrote ServerPiplineFactory class but I don’t know to write in MyServerHandler class. MyServerHandler class is like
public class DiscardServerHandler extends SimpleChannelUpstreamHandler {
private static final String WEBSOCKET_PATH = "/websocket";
@Override
public void messageReceived(ChannelHandlerContext ctx, MessageEvent e) throws Exception {
Object msg = e.getMessage();
//ctx.getChannel().write(msg);
//msg.getClass();
if (msg instanceof HttpRequest) {
//ctx.getChannel().write(msg);
} else if (msg instanceof WebSocketFrame) {
System.out.println("I am WebSocketFrame");
}
}
So I don’t know what should I write if I receive HttpRequest and how to send it back to the browser.
So if write something like below in my jsp file
</script>
var WEBSOCKET_URL = "ws://localhost:8090/websocket";
$(document).ready(function() {
ws = new WebSocket(WEBSOCKET_URL);
ws.onopen = function(event) {
alert("test");
$('#status').text("Waiting....");
};
ws.onmessage = function(event) {
var message = jQuery.parseJSON(event.data);
alert(message);
}
var encoded = $.toJSON("test message");
ws.send(encoded);
});
</script>
<body>
<p id="status"> </p>
</body>
and debug this jsp then it goes to messageReceived then I don’t understand what to do then to how websocket server comunicate with server.
So if someone can help me to find the document on this or explain a bit about this that would be great.
You will need to issue the handshake. Have a look at the websocket example at [1].
