привет всем.
проблема в следующем: создается новый объект, у которого есть отношение один ко многим к другому классу, в данный Лист добавляются новые экземпляры при сохранении базового класса происходит ексепшин, ругается на отсуствие foreignkey — нов базеон есть, скорее всего напутал где-то с аннотациями но самому найти не удалось ..

@Entity
@Table( name = "Bill" )
public class Bill
{
    private long billId;
    private Set<Payment> payments = new HashSet<Payment>();

    public Bill()
    {
    }

    @Id
    @GeneratedValue( strategy = GenerationType.AUTO )
    public long getBillId()
    {
        return billId;
    }

    @OneToMany( fetch = FetchType.LAZY, cascade = CascadeType.ALL, mappedBy = "paymentId")
    public Set<Payment> getPayments()
    {
        return payments;
    }
}

@Entity
@Table( name = "Payment" )
public class Payment
{
    private long paymentId;
    private String name;
    private Bill bill;


    public Payment()
    {
    }


    @Id
    @GeneratedValue( strategy = GenerationType.AUTO )
    public long getPaymentId()
    {
        return paymentId;
    }

    @ManyToOne( fetch = FetchType.LAZY )
    @JoinColumn( name = "billId" )
    public Bill getBill()
    {
        return bill;
    }

}

эксепшен

сам код который вызывает исключение

       Bill bill = new Bill();

        Payment payments = new Payment();
        payments.setName( "fruits" );

        Payment payment2 = new Payment();
        payment2.setName( "goods" );

        bill.getPayments().add( payment2 );
        bill.getPayments().add( payments );

        IBillDAO billDAO = ( IBillDAO ) applicationContext.getBean( "billDao" );
        billDAO.saveBill( bill );
