Glassfish 4 AbstractMethodError: com.objectdb.jpa.EMF.createEntityManager

Hi! I've been trying to get Glassfish 4 (Java EE 7) work with ObjectDB the whole day. It seems to be an error. The same code (adapted to Java EE 6) works perfect in Glassfish 3.1.2.2. I attached the samples as NetBeans projects, so that you could check easier. 1 for GF3 (6) and 1 for GF4 (7). Thanks! #1 2013-07-04 19:17 Hi!

java.lang.ClassCastException in OSGi runtime when loading data from DB

Hello, I'm trying to use ObjectDB in an OSGi environment (Karaf 4.0.7). I'm now facing ClassCastExceptions on my "entity" classes when I try to read data from the DB. In a very old (2011?) forum entry this problem was already discussed and it appears to be related to classloader problems. My entity is a dedicated bundle. I have one bundle with the database service (doing the actual objectdb actions -> persist, query etc). #1 2016-12-09 10:44 Hello, I'm trying to use ObjectDB in an OSGi environment (Karaf 4.0.7).

Missing Data on Retrieval (0, null values)

I try  to export all Objects in an Flatfile-Hiearchy (.csv). But only the first exported Table contains all necessary Data. Most of the others  contains all  Object-Rows', but most Values of the Columns are missing. With a  em.clear() inside the Loop, all tables are exported correctly but the Enity-Keys do not match. I can't get the point - what am i doing wrong?   emf = Persistence.createEntityManagerFactory(dbFile); em = emf.createEntityManager(); #1 2016-04-13 07:07 I try  to export all Objects in an Flatfile-Hiearchy (.csv).

@ElementCollection Set<Integer> is emptied sometimes

Hi! I'm facing a really strange behavior, which I can't yet reproduce, but it happened 3-4 times already. ObjectDB seems to clear some fields that are @ElementCollection Set<Integer> of my objects. They appear HashSet<Integer> in ObjectDB Explorer. The only common thing I've seen is that this MAY happen when schema changes, even though nothing is changed in that Object's class. Any ideas why would this happen and how could it be avoided? Thanks (version 2.5.3 & Tomee & NetBeans) #1 2013-09-13 08:10 Hi! I'm facing a really strange behavior, which I can't yet reproduce, but it happened 3-4 times ...
