I'm new and I have an issue creating a simple example using Primefaces 5.1, Java 7, Tomcat 8
I have used various browsers chrome, firefox, IE with the latest versions but I receive an error:
[14:41:28.338] Firefox can't establish a connection to the server at ws://localhost:8080/Push/primepush/counter?X-Atmosphere-tracking-id=0&X-Atmosphere-Framework=2.2.4-javascript&X-Atmosphere-Transport=websocket&X-Atmosphere-TrackMessageSize=true&X-atmo-protocol=true. @ http://localhost:8080/Push/javax.faces. ... es&v=5.1:1
[14:41:28.339] "Websocket failed. Downgrading to Comet and resending"
And when I try to refresh my page, the html crashes (white page) and I try again and again and some time it works again.
I don't understand where is my mistake, since the example is very simple!
Thank you very much in advance!!!
My pom file is:
