I also get this error, when I try the Hibernate 4.2 on GFv4.

Here is the code I'm using which works on JBoss and GFv4 with ExclipseLink.
The code was from a sample JBoss application.

@PostConstruct
public void retrieveAllMembersOrderedByName()

{ CriteriaBuilder cb = em.getCriteriaBuilder(); CriteriaQuery<Member> criteria = cb.createQuery(Member.class); Root<Member> member = criteria.from(Member.class); // Swap criteria statements if you would like to try out type-safe criteria queries, a new // feature in JPA 2.0 // criteria.select(member).orderBy(cb.asc(member.get(Member_.name))); criteria.select(member).orderBy(cb.asc(member.get("name"))); members = em.createQuery(criteria).getResultList(); }
