Inheritance and overrides in xml constraint-mappings(on one

Hi,

in the Hibernate validator Reference manual (chapter 4.2 - Mapping constraints) there is a warning:

Quote:

Warning

A given entity can only be configured once across all configuration files. If the same class is configured more than once an exception is thrown.

Is there any way around this?

I'm trying to provide support for one large "common" configuration and lots of short "customer specific" configurations, and i would like to be able to override (mostly add) constraints to one class.

Is it maybe possible to load (parse) two different constraint mappings and then merge them into one?

Kind regards,
Tomas

No, there's no way around this restriction, this behavior is defined by the Bean Validation specification.

You could try to merge your mapping files yourself - e.g. using XSLT - and then pass that combined mapping to Hibernate Validator.

Hth,
