hi all,
I want to apply validation using single xml for the whole project.
As writing single xml for each entity class is hard to maintain and creates code duplication.
is there any way to do that ??
any suggestion will be appriciated.
thanks.

There is two different types of XML descriptors in Bean Validation. META-INF/validation.xml is a global descriptor which configures things such as the message interpolator to be used etc. Besides that, it references one or more constraint mapping files which describe the constraints to be applied. You can work with one such mapping file for all your entities or split it up just as you want, but you don't have to create a separate mapping descriptor per entity.

Hth,
