    @Ben - In the XML definition for Validat where you define which rules (assertions) should be applied to which fields (dataElements), thee is a property there called message.

    @Ben - In some cases I can see beans being as "dumb" as you mentioned with only basic getter/setter methods. But if you did not have the bean object, where would functionality like "getAge()" go when a Person only has a birthdate?

    Whenever you talk about validation in an object oriented world, the question comes up as to whether you should be stuffing potentially invalid data into a bean and then validating it, or validating the data, then stuffing it into the bean.
