Hello,

I'm using hibernate's mechanism for validation of objects fields. Thus I have to specify my constraints as annotations in the bean class. Example:



Unfortunately this happens to be a problem for me because:
- From my point of view I want to have a single configuration source for everything concerning hibernate managed objects - this is - OR mapping, links, validation, predefined named queries etc. This of course should be *.hbm.xml file. If this is possible I can generate everything automatically - database schema, beans, DAO, etc.
- I need to keep my object's java code as simple and plain as possible - Pojo (Note: PLAIN with capital letters). This will help me share this object in client side and other modules (I'm OSGi based), without having to worry about the dependent libraries.

So I want to be able to set my validation constraints, using meta data in the *.hbm.xml.
I know I can do this my self, creating a custom event listener, which uses custom meta data from hbm.xml, does the validation, throws exception if necessary, etc. But I think such a feature can be part of the hibernate framework. I believe this will be useful for a lot of people.

What do you think ?

If you want to externalize the validator configuration you have to use constraint mapping files which you can specify in your validation.xml. Bean Validation constraints won't be configurable in the hibernate mapping files.
