I used the the following code in Glassfish build 76

https://blogs.oracle.com/arungupta/resource/totd189-whiteboard-glassfish74.zip

I saw the following error in browser web console

[12:41:22.599] Firefox can't establish a connection to the server at
ws://localhost:8080/whiteboard/websocket. @
http://localhost:8080/whiteboard/websocket.js:42

The same error happens to all my other test apps. Can this be a firewall
issue ?
How do I debug this ?

Note I did update the dependency while building the project via POM.
