my database is externally modified so at some point I need to invalidate the entity cache in my web application.
I wrote a servlet which basically does the following:
@PersistenceContext // injected via Spring
JpaEntityManager nativeEm = em.unwrap(JpaEntityManager.class);
// this method always throws an NPE
Session session = nativeEm.getSession();
I also tried the other flavors of get*Session(), but none of them worked. What is the correct way to get access to an active session?
