The purpose of this project is to provide an annotation based solution to both client side and server side validation. We aim to be mostly compliant to the JSR-303 standard where it has relevance to GWT. Currently the library supports the following:

  • Annotation based field/method validation.
  • Annotations from superclasses and implemented interfaces.
  • Group based selection of methods.
  • Validation on whole objects or single properties. (Client side and Server side)
  • Facilitates writing custom validators.
  • Class level validation.
  • Object graph validation through the @Valid annotation.
  • Groups fully working with "default" grouping and such.
  • @GroupSequence annotation.
  • InvalidConstraint is as JSR-303 compliant as it is likely to get
