Validating entity properties that don't get persisted?

[grettke_spdr]

Say that we've got an entity with some fields that would never get persisted. (for example, we take a credit card number and use it for a purcase). Still, we need to validate it.

In cases like this is it better to use Hibernate validators on fields that are not persisted, or just use a JSF validator instead?

Why wouldn't you use Hibernate Validator annotations for that? Because the word "Hibernate" appears in the name? :)

Yea yea :)

The Seam book I'm reading covers this topic. I suspect they reviewed just to communicate that you can indeed use JSF validations if you wish.

I would rather DRY and use Hibernate Validation annotations.
