= Introduction =
GWT supports a subset of JSR 303 Bean Validation.
+At compile time GWT validation uses the same Validation Provider you use
on the server to create Validator for all your objects
+
+= Quick Start =
+
+Annotate you beans with contstrants
+(see
[http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/validation/src/com/google/gwt/sample/validation/shared/Person.java
Person.java])
+
+{{{
+public class Person implements IsSerializable {
+ @Size(min = 4)
+ private String name;
+}}}
+
+Use the standard validation bootstrap to get a Validator on the client and
validate your object
+(see
[http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/validation/src/com/google/gwt/sample/validation/client/ValidationView.javaValidationView.java])
+{{{
+Validator validator =
Validation.buildDefaultValidatorFactory().getValidator();
+Set<ConstraintViolation<Person>> violations = validator.validate(person);
+}}}
