Hi ,

For me Socket JS is unable to make a connection with the server in cloud foundry . here is my code var socket = new SockJS('/websocket-example'); stompClient = Stomp.over(socket); stompClient.connect({}, function (frame) { setConnected(true); console.log('Connected: ' + frame); showGreeting("Connected"); stompClient.send("/app/user", {}, JSON.stringify({'name': $("#name").val()})); if (stompClient !== null) { stompClient.disconnect(); } setConnected(false); console.log("Disconnected"); });

In Localhost it is working fine but in in cloud foundry it is not working it unable to establish the connection Log: Opening Web Socket...

Can you please tell me what could be the possible reason for this ?

Hi mastershashi, I can just point a couple of directions. Please check out how the WAR got deployed on websocket-cf.cfapps.sap.hana.ondemand.com. Can it be that the context /websocket-example differs? May be the app was deployed this way: https://websocket-cf.cfapps.sap.hana.ondemand.com/info?t=1536215752774 - with empty context? Or with additional level in context, say https://websocket-cf.cfapps.sap.hana.ondemand.com/my_apps/websocket-example/info?t=1536215752774 Was the app deployed on port 80? Maybe you need to specify a port explicitly? Are there any access restrictions on the cloud? Is port 8080 open? And the common advice: search for the difference between localhost and cloud deployments.
