bean-validation

I am using Hibernate validator for form validation in my web-app. I am using the @Length annotation for my String attribute as follows: @Length(min = 5, message = "The field must be at least 5 characters") private String myString; However, I have a need to display a different message if the String exceeds 50 characters. Is there a way to use the out-of-the-box @Length validator to do this? An example of what I would like to do (compiler will not let me) is as follows: @Length(min = 5, message = "The field must be at least 5 characters") @Length(max = 50, message = "The field must be less than

What is the best way to perform client-side form validation using Javascript (with minimal code duplication) when using JSR 303 bean validation on the server side? I'm currently using Spring 3 and the Hibernate Validator . I would suggest that you look at Spring JS, which relies heavily on Dojo. A tutorial can be found here . Easiest way for yourself to start playing with it is to download Spring Roo , create the petclinic sample application with one of the example-scripts (this takes you 5 minutes) and then play around with how the javascript is integrated.

I was trying to create Hibernate Validator bean, and run into this problem creating a bean from static factory method in another Class.

I have a field, say, user_name , that should be unique in a table. What is the best way for validating it using Spring/Hibernate validation? One of the possible solutions is to create custom @UniqueKey constraint (and corresponding validator); and to look-up the existing records in database, provide an instance of EntityManager (or Hibernate Session )to UniqueKeyValidator . EntityManagerAwareValidator public interface EntityManagerAwareValidator { void setEntityManager(EntityManager entityManager); } ConstraintValidatorFactoryImpl public class ConstraintValidatorFactoryImpl implements

I having trouble in showing Invalid value in the error message I have messages.properties file as follows ProductId.exists.custom.validator.validation = A product already exists with product id ${validatedValue}. and following is my custom validtor interface @Target( { METHOD, FIELD, ANNOTATION_TYPE }) @Retention(RUNTIME) @Constraint(validatedBy = ProductIdValidator.class) @Documented public @interface ProductId { String message() default "{ProductId.exists.custom.validator.validation}"; Class<?>[] groups() default {}; public abstract Class<? extends Payload>[] payload() default {}; } Here is

I use javax.validation with Spring. In my test (groovy) I explicitly create validator. import javax.validation.Validation import javax.validation.Validator import javax.validation.ValidatorFactory ValidatorFactory factory = Validation.buildDefaultValidatorFactory() Validator validator = factory.getValidator() when: Set<ConstraintViolation<User>> constraints = validator.validate(entity) My validator in java public class EntityDynamicValidator implements ConstraintValidator<SomeConstraint, Entity> { private GroupService groupService; // This constructor is required, see the link bellow. public
