Hi,
i am getting crazy. Hope someone can point me to the right spot. Suppose the
following tables:
DB-Table: orders
--------
oid int
...
DB-Table: Adress
----------
oid int
order_oid
Now my classes:
@Entity
@Table(name = "orders")
public class Order {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "oid")
int oid;
@OneToMany(mappedBy = "order", fetch = FetchType.EAGER, cascade =
CascadeType.ALL)
List<DeliveryAddress> deliveryAddresses;
....
})
@Entity
public class DeliveryAddress extends Address {
.... (Id and Table annotation from superclass. Id field is also "oid")
@ManyToOne(cascade = CascadeType.ALL)
@JoinColumn(name="order_oid", referencedColumnName="oid")
Order order;
}
Now when i persist my order table, everything is fine but the foreign key
"order_oid" inside the address table is null. Same goes on for other mappings
as well. Whats the problem here?
Thanks.
