Constraint Annotation

[Lopez Mirinda]

Hi,

I have a NotNull annotation defined here which uses the javax.validation.Constraint.

@Documented
@Constraint(validatedBy=NotNullValidator.class) 
@Target( { METHOD, FIELD, PARAMETER })
@Retention(RUNTIME)
public @interface NotNull {

    String message() default "{validator.notNull}";
    
    Class<?>[] groups() default {};  

    Class<? extends Payload>[] payload() default {};     
    
    String getValidationErrorCode() default "test_tanuja";
}


Configuration<?> configuration = Validation.byDefaultProvider().configure();
ValidatorFactory factory = configuration.buildValidatorFactory();
Validator validator = factory.getValidator();


Set<ConstraintViolation<ValidatableObject>> constraintViolations = validator.validate(o);
for (ConstraintViolation<ValidatableObject> value : constraintViolations) {

  Annotation[]  a = annotation.annotationType().getDeclaredAnnotations();
  for (Annotation a1 : a){
    if (a1.annotationType().isAnnotationPresent(javax.validation.Constraint.class)){
	//do something
    }
    if (a1.annotationType().isAnnotationPresent(Target.class)){
	//do something
    }

  }
  Assert.assertEquals("is mandatory", value.getMessage());

} 

a1.annotationType().isAnnotationPresent(javax.validation.Constraint.class) returns false though it is present.
a1.annotationType().isAnnotationPresent(javax.validation.Constraint.class) returns true

Is it possible to get hold of @Constraint and the value of validatedBy?

Thanks in Advance,
Tanuja
