Description

Modifying GORMSessionFactoryDefinitionParser.java by
adding the following to private ClassPathBeanDefinitionScanner configureScanner does not due the trick.

        // support for JPA Entity class
        scanner.addIncludeFilter(new AnnotationTypeFilter(javax.persistence.Entity.class));

I get the following exception when trying to add the com.grailstest.Animal @Entity class:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.grailstest.AnimalValidator': Error sett
ing property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:

Apparently, for every JPA @Entity the appication is looking for a

{CLASS_NAME}

Validator for that entity.

It would also be nice if it could support @Validateable or static constraints like a JPA Entity object supports directly in Grails.
