iScreen is a Java Object Validation Framework, suitable for validating Java Objects (including JavaBeans) to ensure that they are "valid" according to some definition (usually via configuration).

The term 'iScreen' means "information screen," where 'screen' means to protect or conceal. Information, represented by Java objects, are passed through the screen. If they are considered acceptable (i.e. valid), then nothing occurs. If not, then an exception is thrown, allowing the application to notify someone or something of the invalid information.

Configuration is XML, and supports reuse, dynamic error messages, internationalization, conditionals, and much more.
