Hallo Zusammen,

Wie kann man ein zweidimensionales Array von einer eigenen Klasse Position mit Hibernate als Entity-Bean persistieren? -> Position[][] field

Code:
@Entity(name="BS_BATTLEFIELD")
public class Battlefield {

   @Id @GeneratedValue
   private int battlefieldId;
   
   private  Position[][] field;
   
   @OneToMany(cascade = CascadeType.ALL)
   @JoinColumn(name="Battlefield_FK")
   private  Set<Ship> ships = new HashSet<Ship>();

   private int dim;



Alternativ wenn dieses nicht geht. Wie kann ich eine Collection persistieren? (z.B. ArrayList) Bzw. 2 verschachtelte ArrayLists?

Gruß
Michael
