Annotation Type GwtValidation

@Documented
@Target(value=TYPE)
@Retention(value=RUNTIME)
public @interface GwtValidation

Annotates a javax.validation.Validator explicitly listing the classes that can be validated in GWT.

Define the Validator you want, explicitly listing the classes and groups you want to validate.

 @GwtValidation(value = {MyBean.class, MyOther.class},
     groups = {Default.class, OtherGroup.class})
 public interface MyValidator extends javax.validation.Validator {
 }
 

Create and use the validator.

 MyValidator validator = GWT.create(MyValidator.class);
 MyBean bean = new MyBean();
 ...
 Set<ConstraintViolation<MyBean>> violations = validator.validate(bean);
 

You must list all validation groups you are using (as well as groups making up a group sequence)– unless you are only using the Default group, in which case you may omit the "groups" field of the GwtValidation annotation.

NOTE: Validation is done using only the Constraints found on the Classes listed in the annotation. If you have

 class MyBean {
  @Null
  String getName(){return name;}
 }
 class MySubBean extends MyBean {
   @Size(min = 5)
   String getName(){return super.getName();}
 }
 

And then create your ValidatorFactory using
