Look more closely to the example Jeff posted, the DAO manager links a
DAO-interface to a concrete implementation (see interface and
implementation attributes in the DAO config). Something like:

OdmLinkDAO linkDao =3D (OdmLinkDAO)daoManager.getDao(OdmLinkDAO.class);

now i tried this:


OdmLinkDAOImpl linkDao =3D=20
(OdmLinkDAOImpl)daoManager.getDao(OdmLinkDAOImpl.class);

the error i get doesnt really give me a clue:
