I found that it only not worked in Annotated classes. If I used hbm.xml, it works. And I have to add some mapping into the hibernate.cfg.xml: But I tried to add the Annotated in the hibernate.cfg.xml, it didn't worked. What can I do if I really want to use Annotated classes and require to pack them into different JARs ?
