Intro

With this module, validation can be added to your JSF application based on JPA metadata that might already be available within your project. This module also offers extra ExtVal-specific annotations for cases where JPA metadata is not sufficient for the validation.

This module provides:

Simple ExtVal annotations
Cross-validation via annotations
JPA based validation (metadata of JPA annotations are used for UI-Validation)

Note that the modules provide a lot of features which aren't listed here. See the documentation for each module to learn about all available features.
