First websocket program and am getting “WebSocket handshake: Unexpected response code: 404”, error while loading the webpage on resin server

window.onload = init;
var socket = new WebSocket("ws://localhost:8080/WebsocketHome/actions"); 
socket.onmessage = onMessage; 

I have copied this code from and working fine with glassfish server but when i tried with Resin 4.0.47 got handshake error. Tried many basic websocket programs which runs on tomcat and glassfish but not with resin server.Is there any specific configuration for Resin server?

Hey @mahesh. One thing I notice is that your websocket is trying to connect to the local host instead of the devices url. Can you try change ws://localhost:8080/WebsocketHome/actions to ws://<UUID> replacing <UUID> with the RESIN_DEVICE_UUID. Also ensure that you have enabled your deviceURL, you can see the documentation on that here:

@mahesh I would also recommend looking at this example websocket project
