JavaBean Validation JAVA EE
Bean Validation JSR 303, 349 and 380 offer a metadata model and API for Bean validation.
The default metadata source is annotations, with the ability to override and extend the meta-data through the use of XML validation descriptors.
The Validation can be applied to the view layer (e.g. HTML Form, Swing application) or persistent layer etc.
Hibernate Validator is the reference implementation.
For more info please explore Bean Validation in a standalone application example.
