oi,

já passei por isso algumas vezes, veja se isso ajuda

  1. coloque as linhas abaixo no seu web.xml

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

  1. veja se o seu servidor de aplicação já possui as libs jsf-api e jsf-impl, se tiver remova do seu projeto

  2. reinicie o servidor e refaça o deploy

Sim, as libs estão em WEB-INF/lib.

veja se o servidor que está fazendo o deploy também possui essas libs, se tiver remova do seu projeto e tente fazer o deploy novamente.

Marcio_Nogueira

O servidor não possui estas bibliotecas, estas, foram adcionadas ao projeto.
Estou chamando o método de meu bean da seguinte forma: #{login.imprime} que etá gerando a seguinte exceção:

javax.servlet.ServletException: /index.jsp(156,12) '#{loginBean.login}' Target Unreachable, identifier 'loginBean' resolved to null

o que pode estar errado?

Marcio_Nogueira
Marcio_Nogueira
Segue o código do meu bean: 
package bean;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;

@ManagedBean(name="loginBean")
@RequestScoped
public class LoginBean {

	private String login;
	private String senha;
	
	
	public void imprime()
	{
		System.out.println("Olá " + login);
	}
	
	public LoginBean(){}

	public String getLogin() {
		return login;
	}

	public void setLogin(String login) {
		this.login = login;
	}

	public String getSenha() {
		return senha;
	}

	public void setSenha(String senha) {
		this.senha = senha;
	}
}
