Unable to create managed bean

I have a problem here in java that I do not know how to solve nor what it may be because I am learning to program with java for the web and I do not know the possible causes of the following error javax.servlet.ServletException: Unable to create managed bean testeHibernate .

Used code

testHibernate.java

import java.util.List;

 import javax.faces.application.FacesMessage;
 import javax.faces.bean.ManagedBean;
 import javax.faces.bean.ManagedProperty;
 import javax.faces.bean.SessionScoped;
 import javax.faces.context.FacesContext;
 import Classhiber.Utilizador;
 import DAO.UtilizadorDAO;
 @ManagedBean(name = "testeHibernate" )
 @SessionScoped
 public class testeHibernate {

private UtilizadorDAO utdao;

@ManagedProperty(value = "#{utiliza}")  
private Utilizador utiliza = new Utilizador();

public UtilizadorDAO getUtilizadorDAO() {
    return utdao;
}

public void setutilizador(UtilizadorDAO ut) {
    this.utdao = ut;
}

public Utilizador getutilizador() {
    return utiliza;
}

public void setutilizador(Utilizador utz) {
    this.utiliza = utz;
}

public String register() {
    // Calling Business Service
    utdao.addutilizador(utiliza);
    // Add message
    FacesContext.getCurrentInstance().addMessage(null, 
            new FacesMessage("The Employee "+this.utiliza.getUser()+" Is Registered Successfully"));
    return "";
}
}
