I believe the problem lies in the way my class exists:

public boolean existe(Pessoa pessoa) {

    String consulta = "select u from Usuario u where u.email = :pEmail and u.senha = :pSenha";
    TypedQuery<Pessoa> query=getEm().createQuery(consulta,Pessoa.class);
 // TypedQuery<Pessoa> query = em.createQuery("select u from Usuario u where u.email = :pEmail and u.senha = :pSenha",Pessoa.class);

    query.setParameter("pEmail", pessoa.getNomeUsuario());
    query.setParameter("pSenha", pessoa.getSenhaUsuario());

    Pessoa resultado = query.getSingleResult();

    return resultado != null;
}

He is called as follows by Loginbean:

public String efetuaLogin() {
    System.out.println("Fazendo login do usuário "
            + this.pessoa.getNomeUsuario());

    boolean existe = new PessoaDAO().existe(this.pessoa);

    if (existe) {
        return "livro?faces-redirect=true";
    }

    return null;
}

Which in turn is called from executed as follows in Login.xhtml:

Try putting a Try catch - I believe that an exteja occuring a

javax.persistence.Noresultexception:

public boolean existe(Pessoa pessoa) {
     try{   
       String consulta = 
         "select u from Usuario u where u.email = :pEmail and u.senha = :pSenha";
       TypedQuery<Pessoa> query= getEm().createQuery(consulta,Pessoa.class);
       query.setParameter("pEmail", pessoa.getNomeUsuario());
       query.setParameter("pSenha", pessoa.getSenhaUsuario());
       Pessoa resultado = query.getSingleResult();
       return resultado != null;
     } catch (Exception e) {
        System.out.printf("\n Erro %s \n" , e);
        return false; 
     }
}
