Add addJar() and addClassesFromPackage() to EntityManagerFactoryBuilder
-----------------------------------------------------------------------

                 Key: HHH-6483
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6483
             Project: Hibernate Core
          Issue Type: New Feature
          Components: entity-manager
    Affects Versions: 4.0.0.next
            Reporter: Ondra Žižka


JPA's persistence.xml has <jar-file> :

{code}
<persistence>
  <persistence-unit name="TestPU">
    <jta-data-source>java:/TestDS</jta-data-source>
    <jar-file>foo/bar/entities.jar</jar-file>
  </persistence-unit>
</persistence> 
{code}

It would be fine to have  Ejb3Configuration.addClassesFromJar() with the same effect.
Also, Ejb3Configuration.addClassesFromPackage() would be handy, which would find package-info.class and scan it's place (dir, jar, ...) for entities
(assuming a package is in one place only).

After HHH-6159, they would be EntityManagerFactoryBuilder.addClassesFromJar() and EntityManagerFactoryBuilder.addClassesFromPackage(), respectively.

Without this feature, users tend to hack their own scanning or use external lib like Scannotation, which is pitty since scanning code is already in Hibernate.

Thanks for considering.
