AngularJS example assumes JBoss runtime

[arjantijms]

The angular example is assuming that its running on JBoss.

Persistence.xml refers to the jboss namespace: https://github.com/javaee-samples/javaee7-samples/blob/master/jaxrs/angularjs/src/main/resources/META-INF/persistence.xml#L6 and is pointing to the hibernate specific DDL properties.

Uses HQL instead of JPQL: https://github.com/javaee-samples/javaee7-samples/blob/master/jaxrs/angularjs/src/main/java/com/example/rest/NoteResourceImpl.java#L20
