  • Add myfaces-extval-core-.jar and myfaces-extval-property-validation-.jar to the classpath
  • Use JPA annotations within the model (e.g.: @Column(nullable = false) -> the field is required)

That's it!
The table below gives an overview of the validations that are generated, based on JPA annotations.

JPA Annotation
