Where can I find an implementation of javax.validation.*?

Question

I've just included a new library in my project and it's dependent on some classes in javax.validation - which I can't find an implementation of. Is there a free implementation available that can be licensed for commercial, closed-source use?

Solution

Take a look at Hibernate Validator 4, it's an implementation of JSR 303 and uses javax.validation too.

Some examples:-

I downloaded hibernate-validator-4.0.2.GA.jar and included it in my build path, but my application still complains of the same missing class definition. Pardon my ignorance, but how do I specify this jar file as an implementation of the necessary javax.validation classes? I'm not using maven - just eclipse - and I don't understand the directions on the site to which you linked. Sorry!

May I know what class defs are missing? You should be able to just drop it in and use it. What library are you using?

I'm missing (at least) javax.validation.ValidationException. I'm using the JDK 1.6.0 that ships with Mac OS X, and google's appengine sdk (1.4).

Well, I downloaded 4.1.0.Final from sourceforge.net/projects/hibernate/files/hibernate-validator and that missing class def is located in validation-api-1.0.0.GA.jar. Pull this jar into your build path and you will be all set.

Sorry, this turned out to be a gwt-specific problem, resolved by including gwt-servlet-deps.jar in the WEB-INF/lib directory. See groups.google.com/group/google-web-toolkit/browse_thread/thr‌​ead/… Thanks for your help limc
