how to implement form level validation in jsf

Published by Matt Stine

Recently I was faced with the challenge of implementing form-level (or page-level) validation in a JSF-based application. What I mean by form-level validation is the need to evaluate a subset of a form’s fields as a unit, rather than simply validating each field in isolation. An example of this type of validation can be found on a user registration form where one has to select a password in one text field, and then retype the same password in another text field for confirmation.
