1.3. Error messages

Hibernate Validator comes with a default set of error messages translated in about ten languages (if yours is not part of it, please sent us a patch). You can override those messages by creating a ValidatorMessages.properties or ( ValidatorMessages_loc.properties ) and override the needed keys. You can even add your own additional set of messages while writing your validator annotations. If Hibernate Validator cannot resolve a key from your resourceBundle nor from ValidatorMessage, it falls back to the default built-in values.

Alternatively you can provide a ResourceBundle while checking programmatically the validation rules on a bean or if you want a completly different interpolation mechanism, you can provide an implementation of org.hibernate.validator.MessageInterpolator (check the JavaDoc for more informations).
