JSF 2.3 f:websocket java.lang.AbstractMethodError

Question

I have problems rendering f:websocket component. Server is Tomcat v8.5.

Regarding instructions at links:

http://balusc.omnifaces.org/2013/10/how-to-install-cdi-in-tomcat.html

How to update JSF 2.2 to JSF 2.3 using Maven in a Spring Application

https://blog.payara.fish/jsf-2.3-the-websocket-quickstart-under-payara-server

maven dependencies are:

    <dependency>
        <groupId>org.glassfish</groupId>
        <artifactId>javax.faces</artifactId>
        <version>2.3.0</version>
    </dependency>
    <dependency>
        <groupId>javax.enterprise</groupId>
        <artifactId>cdi-api</artifactId>
        <version>2.0</version>
    </dependency>
    <dependency>
        <groupId>org.jboss.weld.servlet</groupId>
        <artifactId>weld-servlet-shaded</artifactId>
        <version>3.0.3.Final</version>
    </dependency>

    <dependency>
        <groupId>org.primefaces</groupId>
        <artifactId>primefaces</artifactId>
        <version>6.2</version>
    </dependency>

This is test.xhtml:

 <h:form>
  <h:outputText value="#{pisSocketView.count}" styleClass="display" />
  <p:commandButton value="Click"
   actionListener="#{pisSocketView.increment}" />

  <f:websocket channel="counter" onmessage="handleMessage" />
 </h:form>

 <script type="text/javascript">
  function handleMessage(message, channel, event) {
   $('.display').text(message);
  }
 </script>


</h:body>
</html>

When I load the page I get error:

Did you do the last step in you third link? You don't explicitly mention it — Kukeltje, May 15 '18 at 08:31
Oh and there already is a JSF 2.3.4... Tried that? And tried running in debug mode? Set breakpoints? — Kukeltje, May 15 '18 at 08:58
And according to your version info etc, your code should end up in https://github.com/javaserverfaces/mojarra/blob/2.3.0/jsf-ri/src/main/java/com/sun/faces/application/ViewHandlerImpl.java#L720 Weird... sure you don't have a different explicit error somewhere? — Kukeltje, May 15 '18 at 09:02
I have put breakpoints at ViewHandlerImpl at 720 and 736 lines, they are inactive and I didn't reach them after page reload. — bmlikota, May 15 '18 at 09:18
No, it is not working yet. Tried with tomcat 9, everything same — bmlikota, May 15 '18 at 09:24
Sorry, I posted a wrong viewhandler reference. Can you check what is the actual viewhandler class that is used when you have a breakpoint at ViewHandlerWrapper.java:328 — Kukeltje, May 15 '18 at 09:42
And sure there is not an old jsf 2.2 still in your classpath? That would be one of the main reasons for an AbstractMethodError (https://stackoverflow.com/questions/12137073/abstract-method-error, never seen it myself) — Kukeltje, May 15 '18 at 09:46
From ViewHandlerWrapper.getWebsocketURL is called DialogViewHandler.getWrapped and wrapped class is org.jboss.weld.module.jsf.ConversationAwareViewHandler which doesn't implement getWebsocketURL method — bmlikota, May 15 '18 at 09:49
That is a PrimeFaces class!!! Are you actually using JSF 2.3 push in a PrimeFaces dialogFramwork dialog? If so please try making a [mcve]. Start without the dialog! — Kukeltje, May 15 '18 at 09:52
I think I don't use push in a PrimeFaces dialogFramwork dialog. I posted full test.xhtml above in the stackoverflow issue — bmlikota, May 15 '18 at 10:03
Everything is ok after I removed dependency: org.ocpsoft.rewrite rewrite-config-prettyfaces Many thanks @Kukeltje! — bmlikota, May 16 '18 at 11:56
