An app-server might wrap queries for various reasons. The initial report here actual came about because WildFly App Server does in fact wrap the {{javax.persistence.Query}} instances Hibernate produces in non-transactional cases.
Currently Hibernate does a direct type check to implement {{javax.persistence.EntityManagerFactory#addNamedQuery}}, checking that the incoming query is of type org.hibernate.jpa.HibernateQuery. This fails when WildFly has wrapped the query.
Same for the {{javax.persistence.StoredProcedureQuery}} branch inside {{#addNamedQuery}} too.
Initial report:
----
Adding a named query at runtime:
{code}
@PersistenceContext
private EntityManager em;
@PostConstruct
public void initNamedQuery()
{
em.getEntityManagerFactory().addNamedQuery("customersOrderByName",
em.createQuery("from Customer c ORDER BY c.name DESC"));
}{code}
Results in:
{code}
Caused by: javax.persistence.PersistenceException: Cannot use query non-Hibernate EntityManager query as basis for named query
