Dear Jugger's, saya buat kelas seperti ini
pubilc class AbsMasterDataApplication<T extends GeneralEntity, E extends GeneralVO>{ public synchronized void updateEntity(T p_entity) { m_hibernateConnection.merge(p_entity); } public void saveViewCurrency(List<vcurrency> p_viewCurrency, UserDimensionVO p_userDimVO)throws UpdateDataException, DeleteDataException, SavingDataException, GeneralException{ List<md_currency> l_mdCurrencyEntityList = Collections.synchronizedList(new ArrayList<md_currency>()); for(vcurrency viewCurrency : p_viewCurrency){ md_currency l_currencyEntity = m_hibernateConnection.find(md_currency.class, viewCurrency.getPrimaryKey()); GeneralFacility.copyPropertiesJustValuesNonNull(l_currencyEntity, viewCurrency); //di update table masternya try{ updateEntity(l_currencyEntity); //???? }catch(Exception ex){ throw new UpdateDataException(ex); } } } Itu koq jadi error yah ? Terima Kasih atas bantuannya. Best Regards, Andi Kusnadi,Skom 0813 1883 92 37 programmer .net, java, streamezzo
