У меня проблема с отображением оракула от Hibernate
Я получил эти классы

и когда я пытаюсь запустить этот тест:

import com.mc.stock.StockDailyRecord;
import com.mc.util.HibernateUtil;
public class App {
public static void main(String[] args) {
System.out.println("Hibernate one to many (Annotation)");
Session session = HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
Stock stock = new Stock();
stock.setStockCode("7052");
stock.setStockName("PADINI");
session.save(stock);
StockDailyRecord stockDailyRecords = new StockDailyRecord();
stockDailyRecords.setPriceOpen(new Integer("2"));
stockDailyRecords.setPriceClose(new Integer("11"));
stockDailyRecords.setPriceChange(new Integer("10"));
stockDailyRecords.setVolume(30L);
stockDailyRecords.setDate(new Date());
stockDailyRecords.setStock(stock);
stock.getStockDailyRecords().add(stockDailyRecords);
session.save(stockDailyRecords);
session.getTransaction().commit();
System.out.println("Done");
}
}
я получаю эту ошибку:

Я новичок в спящем режиме и буду благодарен за любую помощь по этому вопросу
Заранее спасибо.
