I'm trying to use Hibernate Validator 5.0.1 and JSF2.2 but their integration seems to be broken since mojarra version 2.2.3. I've created small app to demonstrate the issue and get exception "javax.servlet.ServletException: Expression Error: Named Object: javax.faces.Bean not found." when running it on Tomcat 7.0.42.
Does anyone else have this problem?

I was able to fix it this way:
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());
}
The problem seems to occur with Mojarra 2.2.3 to 2.2.6 on servlet containers like Tomcat or Jetty as Mojarra tries to load bean validation via JNDI.
I discussed this with Ed Burns at JavaLand 2014 and this issue should be fixed with Mojarra 2.2.7 (see JAVASERVERFACES-3183).

Check the following:
ApplicationFactory applicationFactory = (ApplicationFactory) FactoryFinder.getFactory(FactoryFinder.APPLICATION_FACTORY);
applicationFactory.getApplication().addDefaultValidatorId(BeanValidator.VALIDATOR_ID);
applicationFactory.getApplication().addValidator(BeanValidator.VALIDATOR_ID, BeanValidator.class.getName());
This is does work with Mojara 2.2.2 but doesn't with newer versions. Thanks to Michail for the hint. Here is another way to preconfigure Faces:
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) {
}
}
