I have a simple class where the key needs a Parent and auto generated
long id component.
I am not sure hot to implement this with JPA/JDO, here is a hack I
tried:
@Entity
public class Account {
@Id
private Key key;
..
}
Account account = new Account();
account.setKey(DatastoreServiceFactory.getDatastoreService().allocateIds(parent.getKey(),
Account.class.getSimpleName(), 1).getStart());
em.persist(account);
This seems to work, but I am wondering if there is a more elegant way?
-g.
PS: Remember, I need an auto-generated Id *with* a parent.
