Jakarta Bean Validation

The first draft of the proposal for method-level validation is online. The proposal covers the declaration of parameter as well as return values constraints, extensions to the Validator API, related additions to the meta-data API etc.

So check out the proposal document and let us know what you think, e.g. by sending your questions or remarks to the beanvalidation-dev mailing list.

We have introduced a new section of the website called proposals. This will include wiki-style, work in progress proposals for various features being worked on.

Check out the first proposal page describing ideas and open questions on how to propose dependency injection in ConstraintValidator instances.

The expert groups has begun its work on method-level validation. A feature that was drafted in the latest spec (appendix) but that we could nto finish in time.

You will be able to define constraints on parameters and your favorite interception technology (CDI, @Inject, AspectJ, Spring etc) will call Bean Validation.

The final approach is not fixed yet but it will look like this.

public class BidManager {
    public void placeBid(@Min(0) BigDecimal upTo) { ... }
}

The expert committee has voted yes on JSR-349. That means the work for Bean Validation 1.1 can start. Read some more on Emmanuel's blog.

The next few days will be dedicated getting an expert group up and running.
