jsf - La validación de Bean no funciona con mojarra 2.2.4

bean-validation jsf-2.2 (4)

Pude arreglarlo de esta manera:

public static final String BEANS_VALIDATION_AVAILABILITY_CACHE_KEY = "javax.faces.BEANS_VALIDATION_AVAILABLE"; @PostConstruct private void init() { FacesContext.getCurrentInstance().getExternalContext().getApplicationMap().remove(BEANS_VALIDATION_AVAILABILITY_CACHE_KEY); FacesContext.getCurrentInstance().getExternalContext().getApplicationMap() .put(BeanValidator.VALIDATOR_FACTORY_KEY, Validation.buildDefaultValidatorFactory()); }

Estoy tratando de usar Hibernate Validator 5.0.1 y JSF2.2 pero su integración parece estar rota desde mojarra versión 2.2.3. Creé una aplicación pequeña para demostrar el problema y obtener la excepción "javax.servlet.ServletException: Expression Error: Named Object: javax.faces.Bean not found". cuando se ejecuta en Tomcat 7.0.42.

¿Alguien más tiene este problema?

Esto funciona con Mojara 2.2.2 pero no con las versiones más nuevas. Gracias a Michail por la pista. Aquí hay otra forma de preconfigurar Caras:

public class FacesContextBootstrap implements ServletContextListener { public static final String BEANS_VALIDATION_AVAILABILITY_CACHE_KEY = "javax.faces.BEANS_VALIDATION_AVAILABLE"; @Override public void contextInitialized(ServletContextEvent sce) { FacesContext.getCurrentInstance().getExternalContext().getApplicationMap().remove(BEANS_VALIDATION_AVAILABILITY_CACHE_KEY); FacesContext.getCurrentInstance().getExternalContext().getApplicationMap() .put(BeanValidator.VALIDATOR_FACTORY_KEY, Validation.buildDefaultValidatorFactory()); } @Override public void contextDestroyed(ServletContextEvent sce) { } }

Verifique lo siguiente:

ApplicationFactory applicationFactory = (ApplicationFactory) FactoryFinder.getFactory(FactoryFinder.APPLICATION_FACTORY); applicationFactory.getApplication().addDefaultValidatorId(BeanValidator.VALIDATOR_ID); applicationFactory.getApplication().addValidator(BeanValidator.VALIDATOR_ID, BeanValidator.class.getName());

El problema parece ocurrir con Mojarra 2.2.3 a 2.2.6 en contenedores de servlets como Tomcat o Jetty, ya que Mojarra intenta cargar la validación de beans a través de JNDI.

Discutí esto con Ed Burns en JavaLand 2014 y este problema debería solucionarse con Mojarra 2.2.7 (ver JAVASERVERFACES-3183 ).
