Primefaces push - not reaching endpoint

Question

I have problems with my maven web application implementing primefaces push. I can't figure out why, but I'm not reaching my endpoint.

I'm running on,

• Tomcat 7.0.59
• Java EE 6 Web
• PrimeFaces 5.0
• Atmosphere 2.1.3
• JSF 2.2

I think I should see a message in the output from MailEndpoint but, I only get the message from MailObserver.pushMessage. Any ideas on what is going on?

I found the problem. I changed the wrong web.xml. To make it work, you need to add this to web.xml

<servlet>
    <servlet-name>Push Servlet</servlet-name>
    <servlet-class>org.primefaces.push.PushServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <async-supported>true</async-supported>
</servlet>
<servlet-mapping>
    <servlet-name>Push Servlet</servlet-name>
    <url-pattern>/primepush/*</url-pattern>
</servlet-mapping>
