Can I use a WebSocket in Axon.ivy 6.x?
Hi ivyTeam
I need to have a WebSocket in an ivyProject. I thought about using Primefaces Push Endpoints for this. I know about [this solution for ivy 4.x and 5.x][1] but this doesn't seem to work anymore. I get the following errors and no endpoints are available:

Here's what I added to the web.xml:
<servlet>
<servlet-name>Push Servlet</servlet-name>
<servlet-class>org.primefaces.push.PushServlet</servlet-class>
<async-supported>true</async-supported>
<init-param>
<param-name>org.atmosphere.useWebSocketAndServlet3</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>org.atmosphere.websocket.suppressJSR356</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>Push Servlet</servlet-name>
<url-pattern>/primepush/*</url-pattern>
</servlet-mapping>
And what I added to the webapps/ivy/WEB-INF/lib directory:
atmosphere-runtime-native-2.4.14.jar
atmosphere-compat-tomcat-2.0.1.jar
atmosphere-compat-jbossweb-2.0.1.jar
atmosphere-compat-tomcat7-2.0.1.jar
I saw that you implemented a websocket for the chat feature in the Portal (XIVY-519) so it should still work. But in the Portal project, the atmosphere jar is directly in the project so the old way in the question linked above probably doesn't work anymore...
TLDR; Could you give me a hint how I can create my own WebSocket endpoints in ivy 6.x?
