Here is the Session Bean
| package org.seam.ejemplo.login.session;
|
| import java.util.List;
|
| import javax.ejb.Stateless;

usuario=:usuarioParam")

#{cliente.usuario} no fue registrado. Regístrese");

Here is the interface

|
| import javax.ejb.Local;
|
| import org.jboss.seam.annotations.WebRemote;

| /**

| * @return

Here is the page
