Abstract

Validating user input is a major part of any web application. JSF provides a number of tags to enable basic validation and makes it pretty easy to build custom validators. JSF 2 makes validation even simpler by providing out-of-the-box support for popular Bean Validation (JSR 303). RichFaces takes validation to the next level and extends Bean Validation by providing client-side validation. Client-side validation allows validation to be performed on the client based on Bean Validation constraints. This is a musthave feature for high-performance enterprise web sites. In addition to client-side validation, RichFaces also provides a cross-field or object validation feature where one or two fields can be validated together. That’s exactly what we are going to cover in this chapter.
