Bean validation sample app ?

[misqu23]

Hi

I'd like to see bean validation in action and probably include this feature in my app. I have downloaded jboss 6 M1, my app is working correctly.

But I don't know how to apply bean validation on persisting and updating entities.

I'm wondering if there is available demo app which shows the new features of the jboss in action, which can be treated as a reference implementation and the strong programming pattern ?

I have read the doc you posted. Thanks for that link.

But I still have some problems.

The bean validation docs says that it should be possible to inject the validator instance, in my stateless session bean when I try to inject validator using well known @Resource annotiation I get the following exception during deployment :

Also when I try to inject using @Inject annotation I get the null pointer exception.

The other problem is validation of the entity when persisting or updating the docs says :

If you are using JPA 2 and Hibernate Validator is in the classpath the JPA2 specification requires that Bean Validation gets enabled. The properties javax.persistence.validation.group.pre-persist,javax.persistence.validation.group.pre-update and javax.persistence.validation.group.pre-remove as described in Section 6.2.1, “Hibernate event-based validation” can in this case be configured inpersistence.xml. persistence.xml also defines a node validation-mode while can be set to AUTO, CALLBACK,NONE. The default is AUTO.

My question is how can I tell jboss that I wan't to use jpa2, should I only change the version from 1.0 to 2.0 in the presistence.xml.

As you can see I need (and I think that others too) some skeleton app with the demonstration of the new features of the jboss.
