Hi all, I add openjpa dev list into the loop as well. Looking forward to the expertise comments from both communities.

To: [email protected] Hi devs, I'm looking for if EJB persistence spec has any word on the requirement of object movie_in and movie_out (see code snippet below). Should they be movie_in == movie_out or movie_in.equals(movie_out)? EntityManager em = getEntityManager(); Movie movie_in = new Movie("MovieNameA", "DirectorNameA", "DescriptionA"); em.persist(movie_in); em.flush(); Movie movie_out = (Movie) em.createQuery("select m from MOVIE m where m.name = 'MovieNameA' ").getSingleResult(); I'm hunting in the ejb3.1 spec and persistence2.0 specs for a while, but failed to find the requirement. Can someone give me a hint on this? Thanks in advance. -- Best regards, Han Hong Fang (Janet) hanhongfang AT apache.org -- Best regards, Han Hong Fang (Janet) hanhongfang AT apache.org
