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

Front-end
#1

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:

[code]
<%@ page language=“java” contentType=“text/html; charset=ISO-8859-1” pageEncoding=“ISO-8859-1”%>

<%@ taglib prefix=“f” uri=“http://java.sun.com/jsf/core”%>
<%@ taglib prefix=“h” uri=“http://java.sun.com/jsf/html”%>

<%@ taglib uri=“http://richfaces.org/a4j” prefix=“a4j”%>
<%@ taglib uri=“http://richfaces.org/rich” prefix=“rich”%>

<meta http-equiv=“Content-Type” content=“text/html; charset=ISO-8859-1”>
<title>Insert title here</title>

<body>
<f:view>
<h:form>
<rich:panel header=“Ola RichFaces” style=“width: 300px”>
<h:outputText value=“Seu nome: " />
<h:inputText value=”#{helloRichBean.nome}"/>
<a4j:commandButton value=“Dizer ola” reRender=“olaPainel” />

				&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;

</html>[/code]

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.

Erro:

– RESOLVIDO –

Basta acrescentar algumas tags nos seus arquivos de configuração.

Arquivo: web.xml
Acrescentar:

&lt;context-param&gt; &lt;param-name&gt;org.ajax4jsf.VIEW_HANDLERS&lt;/param-name&gt; &lt;param-value&gt;com.sun.facelets.FaceletViewHandler&lt;/param-value&gt; &lt;/context-param&gt;

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

Arquivo: faces-config.xml
Acrescentar:

&lt;application&gt; &lt;view-handler&gt;org.ajax4jsf.application.AjaxViewHandler&lt;/view-handler&gt; &lt;/application&gt;

vc definiu algum viewHandler no seu faces-config.xml?

Posta o seu web.xml pra gente.

Sucesso!!!

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?
