Javax.servlet.ServletException: Tentativa ilegal de definir ViewHandle [resolvido]

Pessoal,

Primeiramente eu fiz minha aplicação usando somente JSF e Hibernate então estava funcionando normal. Mas agora estou tentando usar o richfaces e esta aparecendo uma mensagem de erro. Estou procurando na net sobre essa mensagem mas não acho em lugar algum falando sobre o mesmo.
Obs: Estou usando JSF 2.0, Hibernate, Richfaces 3.3.3 e Tomcat 6.0.

As aterações que eu fiz para usar o richfaces foram:

Adicionar as libs:
richfaces-api-3.3.3.Final.jar
richfaces-impl-3.3.3.Final.jar
richfaces-ui-3.3.3.Final.jar
Obs: Não sei se tenho que incluir a lib richfaces-impl-jsf2-3.3.3.Final.jar, porém já testei com e sem esse lib e não funciona mesmo.

criar a página helloRich.jsp:

&lt;%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%&gt;

&lt;%@ taglib prefix="f"  uri="http://java.sun.com/jsf/core"%&gt;
&lt;%@ taglib prefix="h"  uri="http://java.sun.com/jsf/html"%&gt;

&lt;%@ taglib uri="http://richfaces.org/a4j" prefix="a4j"%&gt;
&lt;%@ taglib uri="http://richfaces.org/rich" prefix="rich"%&gt;

&lt;!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"&gt;

&lt;html&gt;
	&lt;head&gt;
		&lt;meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"&gt;
		&lt;title&gt;Insert title here&lt;/title&gt;
	&lt;/head&gt;
	&lt;body&gt;
		&lt;f:view&gt;
			&lt;h:form&gt; 
				&lt;rich:panel header="Ola RichFaces" style="width: 300px"&gt;
					&lt;h:outputText value="Seu nome: " /&gt;
					&lt;h:inputText value="#{helloRichBean.nome}"/&gt;
					&lt;a4j:commandButton value="Dizer ola" reRender="olaPainel" /&gt;
					
					&lt;h:panelGroup id="olaPainel" layout="block"&gt;
						&lt;h:outputText value="Ola, " rendered="#{not empty helloRichBean.nome}" /&gt;
						&lt;h:outputText value="#{helloRichBean.nome}" /&gt; 
						&lt;h:outputText value="!" rendered="#{not empty helloRichBean.nome}" /&gt;
					&lt;/h:panelGroup&gt;
				&lt;/rich:panel&gt;
			&lt;/h:form&gt;
		&lt;/f:view&gt;
	&lt;/body&gt;
&lt;/html&gt;

Criar o HelloRichBean.java:

package appjsf_sistemafinanceiro.visao;

public class HelloRichBean {
	private String nome = null;

	public String getNome() {
		return nome;
	}
	
	public void setNome(String nome) {
		this.nome = nome;
	}
}

Registrar o Bean no faces-config.xml:

&lt;managed-bean&gt;
  &lt;managed-bean-name&gt;helloRichBean&lt;/managed-bean-name&gt;
  &lt;managed-bean-class&gt;appjsf_sistemafinanceiro.visao.HelloRichBean&lt;/managed-bean-class&gt;
  &lt;managed-bean-scope&gt;session&lt;/managed-bean-scope&gt;
 &lt;/managed-bean&gt;

Se alguem poder me ajudar eu agradeço.

Basta acrescentar algumas tags nos seus arquivos de configuração.

Arquivo: web.xml
Acrescentar:

<context-param> <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name> <param-value>com.sun.facelets.FaceletViewHandler</param-value> </context-param>

=================

Arquivo: faces-config.xml
Acrescentar:

<application> <view-handler>org.ajax4jsf.application.AjaxViewHandler</view-handler> </application>

Ahh outra coisa. No tópico que eu postei além do erro que esta acontecendo eu estava com dúvida em qual lib de richfaces-impl eu deveria usar, se era a richfaces-impl-3.3.3.Final.jar ou richfaces-impl-jsf2-3.3.3.Final.jar. Então atráves do link http://community.jboss.org/wiki/RichFaces333andJSF20 eu achei a solução para o meu problema e também descobri que eu deveria utilizar a lib richfaces-impl-jsf2-3.3.3.Final.jar ao invés da lib richfaces-impl-3.3.3.Final.jar.

Abaixo esta meu arquivo web.xml e faces-config.xml para deixar mais claro:

O estranho é que seu faces-config.xml tá do jsf 1.2.
É assim mesmo?
