Код, в котором хранятся Клиент и Аккаунт

     ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext(new     String[] {

    Customer customer = new Customer();

customer.addAccount(acc);


CustomerDAOImpl customerDAOImpl = (CustomerDAOImpl) appContext.getBean("customerDAOTarget");
   customerDAOImpl.addCustomer(customer);

Мой вопрос: теперь он работает без транзакций.Поскольку даже после того, как клиент вставлен в базу данных в то время, когда возникает исключение, данные не добавляются в таблицу счетов.В этот момент я хочу удалить запись в таблице клиентов.Что я должен сделать, чтобы выполнить это?
