I dont think you need to do build level changes. If you have a ValidatorMessages.properties (and ValidatorMessages in other locales) available in the Current ClassLoader, Hibernate should be able to use that instead of the default validator messages that come bundled with it. Atleast thats how my reading of the Hibernate code indicates. I havent tried this, but if you have a ValidatorMessages.properties in ur EAR archive, that should suffice.
