problem when using javax.validation.Validator and others

Question

I'm trying to validate something using the GWT BeanValidation but these two lines are giving me some trouble:

Validator validator=Validation.buildDefaultValidatorFactory().getValidator();
Set<ConstraintViolation<Contact>> violations = validator.validate(contact, Default.class);

The thing is, I have imported the corresponding classes:

import javax.validation.ConstraintViolation;
import javax.validation.Validation;
import javax.validation.Validator;
import javax.validation.groups.Default;

But still, the Validator, Validation, ConstraingViolation and Default references in the code are underlined in red and the error they show is:

javax.validation.Validator can not be found in source packages. Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly.

I have checked that the necessary lib validation-api-1.0.0.GA.jar is in the classpath and everything seems normal.

Anyone happens to know what could be the problem?

thanks!!

So, your IDE is Eclipse. Have you checked that the JAR file is present at the _Project > Properties > Java Build Path > Libraries_ page? — Tomas Narros, Mar 24 '11 at 11:58
yes, as I said above, I checked it. It's under the Maven Dependencies Library. — Neets, Mar 24 '11 at 12:03

I see only two possibilities

Check the size of jar file , either in your local maven repository which your build path is pointing to or check that in your eclipse by browsing its source code to double check its there :)
Have you inherited this is any awt module using ? Can you check its syntax or if it is really required?

yeah, the problem is that GWT doesn't let you use any class freely. First it has to be inherited via a module in the gwt.xml. In the end, I chose to work with another validation library: GWT-VL – Neets Mar 28 '11 at 15:40

Do you have validator-implementation in your classpath? AFAIK, javax.validation is only the API (interfaces), you'll need an actual validator-implementation to use it. See for example Hibernate Validator.
