[jumapama]

Hello, i have a problem which i have spent a lot of time. Somebody can show me a converter and selectItems example. I have the next code:


  | 
  | @Name("cuentaConverter")
  | @org.jboss.seam.annotations.faces.Converter(forClass=Cuenta.class)
  | public class CuentaConverter implements Converter, Serializable{
  | 
  | 	private static final long serialVersionUID = 1L;
  | 	@In(create=true)
  | 	private EntityManager entityManager;
  | 	
  | 	@Transactional
  | 	   public Object getAsObject(FacesContext context, UIComponent component, String value) throws ConverterException
  | 	   {
  | 		  String id=value;
  | 		  if(id!=null)
  | 	      return entityManager.find(Cuenta.class, id); 
  | 		  return null;	      
  | 	   }
  | 
  | 	   public String getAsString(FacesContext context, UIComponent component, Object value) throws ConverterException
  | 	   {
  | 		  if(value instanceof Cuenta){
  | 			  Cuenta cuenta=(Cuenta) value;
  | 			  return cuenta.getIdCuenta().toString();
  | 		  }
  | 		  else return null;
  | 	      
  | 	   }
  | }
  | 
  | @Name("login")
  | @Scope (SESSION)
  | @Stateful
  | public class LoginFacade implements LoginFacadeLocal{
  | 	
  | 	@PersistenceContext 
  | 	private EntityManager entityManager;
  |     
  | 	@In(required=false) @Out(required=false)
  | 	private Cliente user;
  | 
  | 	@In(required=false) @Out(required=false)
  | 	private Cuenta account;	
  | 	
  | 	public void setUser(Cliente persona){
  | 		this.user=persona;		
  | 	}
  | 	  
  | 	public Cliente getUser(){
  | 		return this.user;
  | 	}
  | 	
  | 	public void setAccount(Cuenta cuenta){
  | 		this.account=cuenta;		
  | 	}
  | 	  
  | 	public Cuenta getAccount(){
  | 		return this.account;
  | 	}	
  | 			
  | 	public Cliente findPersonaByPassword(){
  |     	
  |         Cliente entity = null;
  |         try {
  |         	entity=(Cliente)entityManager.createQuery("SELECT OBJECT(c) FROM Cliente c " +
  | 			"WHERE c.password=#{cliente.password}")
  | 			.getSingleResult();
  |         }
  |         catch (NoResultException noneFound) {
  |         }
  |         return entity;
  |     }   
  | 	
  |     public Cliente findPersonaByUsuario(){
  |     	
  |         Cliente entity = null;
  |         try {
  |         	entity=(Cliente)entityManager.createQuery("SELECT OBJECT(c) FROM Cliente c " +
  |         			"WHERE c.usuario=#{cliente.usuario}")                    
  |         	.getSingleResult();
  |         }
  |         catch (NoResultException noneFound) {
  |         }
  |         return entity;
  |     }   
  |     @Create
  |     public String valida(){
  |         Cliente cliente;
  | 		if((cliente=findPersonaByUsuario())!=null 
  | 				&& findPersonaByPassword()!=null)			
  | 		{  
  | 			setUser(cliente);
  | 			if (user instanceof Administrador)return "administradores";
  | 	        else if (user instanceof Cliente) return "clientes"; 
  | 			
  | 		}
  | 		return "clientes";
  |     }
  | 	
  |     @Destroy
  |     @Remove
  |     public void destroy(){}
  |     
  | }
