[jboss-user] [JBoss Seam] - Problem using Red Hat Developer Studio to create a new Seam

[daymel]

Hello:

I am new in Seam and in RHDS. I am try to create a simple app that connect to Oracle database and receive a group of records. I created a new Action with that code:

@Stateless
@Name("tipoequipo")
public class TipoEquipoListAction {
	
    @Logger private Log log;
	
    @In 
    FacesMessages facesMessages;
    
    @PersistenceContext
    private EntityManager em;
    
    @DataModel
    private List tipoEquipoList;
    
    
    //seam-gen method
    public String obtenerTipoEquipos()
    {
        //implement your business logic here
    	tipoEquipoList = em.createQuery("select * from TipoEquipo").getResultList();
        log.info("tipoequipo.obtenerTipoEquipos() action called");
        //facesMessages.add("obtenerTipoEquipos");
        return "success";
    }
}

When I run the page that call this action I receive the following error message:
