Spring-Modules Validation

Spring Modules is a collection of tools, add-ons and modules to extend the Spring Framework. The core goal of Spring Modules is to facilitate integration between Spring and other projects without cluttering or expanding the Spring core. Features: * Provides spring integration with commons-validator. * Provides an extensive framework for declaratively define validation constraints on domain models using XML, Java 5 annotations and/or proprietary validation language (Valang). * The framework is based on Spring's Validator infrastructure.
