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(){}
|
| }
|
| <h:form>
| <h:panelGroup>
| <h:selectOneMenu id="cuenta" value="#{account}">
| <s:selectItems value="#{user.cuentas}" var="c"
| label="#{c.idCuenta}" />
| <h:message for="cuenta"></h:message>
| </h:selectOneMenu>
| </h:panelGroup>
| <h:commandButton type="submit"
| action="#{clienteFacade.disponibleCuenta}" />
| </h:form>
