Hi,
my problem is finally resolved by changing the sequence manager in
repository.xml file, ->SequenceManagerNativeImpl,
and suprisingly, even no need to use the method getObjectId can be
displayed the id:
Department bean = new Department();
bean.setName("JDO Development");
pm.currentTransaction().begin();
pm.makePersistent(bean);
pm.currentTransaction().commit();
int i = bean.getId(); // got it here.
Thank you guys very much.
