Hi konstantin thanks alot for your reply, do you mean that i shoul have :
@Entity
@Table(name = "Daughter")
@IdClass(DaughterKey.class)
@PrimaryKeyJoinColumn(name = "Mother_id")
public class Daughter extends Mother{
private String daughter_id;
@Id
private DaughterKey myKey=new DaughterKey();
public Daughter(){
super();
myKey.setMotherId(super.getId());
myKey.setDaughterId(getDaugherId())),
}
//.. getter/setter for all fields
}
instead of :
@Entity
@Table(name = "Daughter")
@IdClass(DaughterKey.class)
@PrimaryKeyJoinColumn(name = "Mother_id")
public class Daughter extends Mother{
@Id
private String daughter_id;
public Daughter(){ super();}
//.. getter/setter for all fields
}
Is it your idea ?
