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:
org.jboss.seam.InstantiationException: Could not instantiate Seam component: tipoequipo
