The validate method has its shortcomings. Often, for example, validation code is heavily duplicated throughout an application because many fields require the same validation logic. Any change in the validation logic for similar fields requires code changes in several places, as well as recompilation of the affected code.
Whereas the Validator framework comes prepackaged with several validation routines, making the transition from hard-coded validation logic painless. Instead of coding validation logic in each Form Bean�s validate( ) method, with Validator you use an XML configuration file to declare the validations that should be applied to each Form Bean. If you need a validation not provided by Validator, you can plug your own custom validations into Validator. Additionally, Validator supports both server-side and client-side (JavaScript) validations whereas Form Beans only provide a server-side validation interface.
