Bean Validation constraint(s) violated while executing Automatic Bean Validation on callback event:'prePersist'

Question

I would like to store birthdate so I chose date at MySQL, when I create my entities based in my database, it turns out like this:

import java.util.Date;      // ..code     @NotNull(message="fill you birthdate")     @Temporal(TemporalType.DATE)     private Date birthdate; 

But when I try to persist it gives me this error:

Bean Validation constraint(s) violated while executing Automatic Bean Validation on callback event:'prePersist'. Please refer to embedded ConstraintViolations for details.

What am I doing wrong here ? I was reading something about define time zone in Google, I'm from Brazil, how should I do that ?

EDIT

I got the same problem, but after hours looking for the answer, Finally I Found it.... You should edit your AbstractFacade.java class and add this code

public void create(T entity) {      ValidatorFactory factory = Validation.buildDefaultValidatorFactory();     Validator validator = factory.getValidator();     Set<ConstraintViolation<T>> constraintViolations = validator.validate(entity);     if(constraintViolations.size() > 0){         Iterator<ConstraintViolation<T>> iterator = constraintViolations.iterator();         while(iterator.hasNext()){             ConstraintViolation<T> cv = iterator.next();             System.err.println(cv.getRootBeanClass().getName()+"."+cv.getPropertyPath() + " " +cv.getMessage());              JsfUtil.addErrorMessage(cv.getRootBeanClass().getSimpleName()+"."+cv.getPropertyPath() + " " +cv.getMessage());         }     }else{         getEntityManager().persist(entity);     } } 

Now this method will alert you which property and why it fails the validation. I hope this works for you, as it does for me.
