Question

In Java Bean Validation (JSR 303), is there a way to programmatically (dynamically) add constraints in the code before the validate method is called (in addition to the constraints declared as annotations in the bean)?

Answer 1

The specification says

This JSR defines a metadata model and API for JavaBean validation. The default metadata source is annotations,
with the ability to override and extend the meta-data through the use of XML validation descriptors.

so I guess if any programmatic configuration exists, it is implementation specific and thus nonportable.
