when i try to retireve data from coding



UserBean obj = (UserBean) pri.get(UserBean.class, Long(1));



and when i try to get address of user



Set<AddressBean> set = view.getAddressBean();
Set<AddressDTO> addressList = new HashSet<AddressDTO> ();
if (set != null) {
for (AddressBean bea : set) {
AddressDTO aDTO = new AddressDTO();
AddressBean.convertBeanToDTO(aDTO, bea);
addressList.add(aDTO);
}
}

as this
jboss throws error
