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 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?

Hi Ivy team, I used project-build-plugin 6.1 SNAPSHOT
However I was failed to build project due to source level: Java 1.8.

getProcessElement() not found when migrating to Ivy 6

A1234 — Mon, 14 Dec 2015 15:03:18 -0500

Hello,

While testing migration of various projects to Ivy 6.0, I encountered a problem with a method that does not exist anymore.

  /** 
   * Find the current process name. 
   * 
   * @return fully qualified process name 
   * @throws Exception 
   */ 
    public static String getName() throws Exception {
        return SecurityManagerFactory.getSecurityManager().executeAsSystem(new Callable<String>() {
            public String call() {
                IProcess process = ProcessNavigationUtil.getProcess(MetaData.getProcessElement());

                if (process != null) 
                    return process.getPath();

                return null;
            }
        });
    }

In the previous code, the method MetaData.getProcessElement() is not found. By looking in Ivy 5.1.7, it was implemented as:

  public static ZObject getProcessElement()
  {
    return (ZObject)IvyThreadContext.getIvyThreadLocalValue("processElement");
  }

Now the method has been removed, and a new method getProcessElementId() was added, but with a new signature:

  public static PID getProcessElementId()
  {
    return (PID)IvyThreadContext.getIvyThreadLocalValue("processElement");
  }

I didn't found this change in the migration documentation. Can I know the reason for removing the previous method and what are the alternative in order to get the current process name? Thanks.
