Pessoal,

Eu estou desenvolvendo um projeto utilizando jsf 2.0 e estou com um erro chatinho aqui. Já procurei mas não encontrei como solucioná-lo =/

O erro ocorre quando eu clico no botão “ENTRAR”.

Tenho um xhtml

E um controller

package br.com.nativa.controller;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

import br.com.nativa.bean.Cliente;

@ManagedBean
@SessionScoped
public class ClienteController {
	
	public void handleUser(){
		
		Cliente cli = new Cliente();
		cli.getCep();
		System.out.println("Ok");
	}

}

O meu stacktracer é o seguinte:

não esta faltando as taglibs, tipo expression language, os jars do jstl e a declaração na página?

att,

Oi pedruhenrik,

Em primeiro lugar, obrigada por responder
Então, eu já coloquei todos os jars do jstl… E nada =/

Ola amigo, vc declarou seu controler no manageBean ou se estiver usando a injeção de dependencia, marcou o seu controle para ser injetado, o que eu identifiquei nao é erro da EL e sim do atributo conttroler que nao foi localizado, ou seja nao está carregado no seu managebean.

Espero ter ajudado

Paulo,

Sinceramente, eu não entendi o que você quis dizer, pq o meu ClienteController está declarado como @ManagedBean… seria isso?

P
paulo1911

Olá amigo, mas o fato de estar declarado nao quer dizer que está injetado. Vc vai precisar debugar a crição desse objeto, talvez no construtor. Para saber se ele está sendo instanciado, e talvez esteja ai o problema.

Então…

Eu até tentei debugar, o problema é que ele nem entra no construtor e já dá o erro =/

P
paulo1911

Aqui eu identifiquei que seu controller nao está sendo encontrado, por isso indiquei debugar o construtor.

veja:

javax.faces.el.EvaluationException: javax.el.PropertyNotFoundException: /jsp/menu.xhtml @23,94 action="#{clienteController.handleUser}": Target Unreachable, identifier 'clienteController' resolved to null

Voce usa JSF 2.0?, verifique as configurações no seu web.xml e veja se o listener do JSF está sendo carregado, pois oq ue parece é que não está carregando seus beans declarados com o @ManagedBean

veja esse link

Paulo, creio q vc não mandou o link… =/

mas o meu web.xml está assim

    &lt;description&gt;State saving method: 'client' or 'server' (=default). See JSF Specification 2.5.2&lt;/description&gt;
    &lt;param-name&gt;javax.faces.STATE_SAVING_METHOD&lt;/param-name&gt;

  &lt;listener&gt;
    &lt;listener-class&gt;com.sun.faces.config.ConfigureListener&lt;/listener-class&gt;
  &lt;/listener&gt;
&lt;/web-app&gt;

Creio eu que esteja correto, pelo pouquinho q estudei de JSF… mas… Não sei.rs

Só consegui sair desse erro depois de dar um Clean no Projeto e no Tomcat.
