Is it possible to validate a collection of objects in JSR 303 - Jave Bean Validation where the collection itself does not have any annotations but the elements contained wit
Yes, just add @Valid to the collection.
@Valid
Here is an example from the Hibernate Validator Reference.
public class Car { @NotNull @Valid private List passengers = new ArrayList(); }
This is standard JSR-303 behavior. See Section 3.1.3 of the spec.
