[jboss-user] method not found

[Ernesto Cullen]

Hi all,
  I am learning Seam, and have a problem with a simple app. I have one
stateless ejb, one entity ejb, and a couple of pages. I want to call a
method on the stateless ejb from a button in the first page, like this:
<h:commandButton value="Aceptar" action="#{manager.aceptar
}"></h:commandButton>

My ejb is as follows:
------------------------------------
@Stateless
@Name("manager")
public class AlumnosManager implements AlumnosManagerLocal {

@PersistenceContext(unitName="ejemplo1SeamPU")
private EntityManager em;
public String aceptar()
{
System.out.println("Aceptar alumno");
return "datosAlumno";
}
}
--------------------------------------

simple enough, but when I hit the button I get the following error. Can
somebody help me?

TIA

Ernesto Cullen
