- mappedBy and inheri 2007-07-13 - By denpet

I have a problem with extending entity classes and OneToMany relations.
(The problem is not the same as http://jboss.com/index.html?module=bb&op
=viewtopic&t=111688)
My superclass, Inventory, has a column, station, which is used to map a
relation with the Station entity
| public class Station implements Serializable {
| @(protected)(cascade = ALL, mappedBy = "station")
| private Set<InventoryType1> inventory1 = new HashSet<InventoryType1>(0);
| }
|
| public class Inventory implements Serializable {
| /** Station */
| @(protected)
| @(protected)(name = "station_id")
| private Station station;
| }
|
| public class InventoryType1 extends Inventory implements Serializable {
| }
|
This fails with a
anonymous wrote : org.hibernate.AnnotationException: mappedBy reference an
unknown target entity property: Inventory1.station in Station.inventory1
As Inventory1 has no station column. In my opinion is has, as it inherits the
columns of Inventory.
I could probably work around this by moving the station_id to each sub entity,
but it really belongs in the super class as it's common for all Inventory types
.
