Thank you very much. WHere do I specify that the JPA annotated classes have to be loaded automatically? I used the entry property name="hibernate.archive.autodetection" value="class, hbm" and still see that when I refer to an entity class, it gives me an exception that the entity class is not mapped. When I add an entry mapping class in hibernate.cfg.xml, the error disappears. Also, I see that the dvdstore demo does not use any entry to autodetect the schema and this is where I missed the link.
