Jsf-naming:namingContainer leads to ClassCastException

Question

Hi,
I am having a problem creating a JSF-Portlet (JSF 1.2) in a WebLogic Portal 10.3.2
I am trying to create a portal JSF-Portlet using the jsf-1.2_09 libraries (WebLogic default). The Portlet works great until I try to integrate the <jsf-naming:namingContainer tag into my jsp.
I am using the Oracle Tutorial "Developing JSF Portlets with WebLogic Portal"
The JSP is really simple
*<code>*
<%@ page language="java" contentType="text/html;charset=UTF-8"%>
<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<%@ taglib prefix="jsf-naming" uri="http://bea.com/faces/adapter/tags-naming"%>
<f:view>
<jsf-naming:namingContainer id="loginJSFPortlet" >
<h:outputText value="Login Test"/>
<h:form>
<h:commandButton id="loginButton" value="Anmelden" action="login"/>
</h:form>
</jsf-naming:namingContainer>
</f:view>
*</code>*
When calling the portal desktop the following exception is thrown
*<exception>*

When I don't use the namingContainer tag everything works fine.
Any Idea what's going wrong here?
Thkx in advance
Edmund

Hello Edmund,
The "jsf-naming" tag library you are importing is from the WLP "native" JSF 1.1 portlet bridge, which uses an entirely different way to render JSF as portlets than the new JSR329 JSF 1.2 to Java Portlet 2.0 bridge that you are using (the "GenericFacesPortlet"). Unfortunately, the jsf-naming tags are not compatible with the JSR329 bridge.
I'm not a JSF expert, so unfortunately I can't suggest an equivalent way of doing what you want to do, but I am sure it is possible. Hopefully someone else on here with JSF expertise can help you out.
