Hi guys

I have an object say Basket that has a collection of Fruit which is a super class of Apple and Orange.
What I'm trying to do is fetching a Basket with all of its Fruit objects initialized so I don't get class cast exception with polymorphism and proxy obj when doing something like

(Apple)(basket.getBasketFruits().getIterator().next()) ;

And consider the following criteria :

Criteria criteria = getSession().createCriteria(Basket.class);
criteria.add(Restrictions.eq("id", basketId));
criteria.setFetchMode("basketFruits.fruit", FetchMode.JOIN);
return (Basket) criteria.uniqueResult();


with the above criteria, the Fruit objects in the collection of Basket is still not initialized, could someone please point me to the right criteria query ? Below is the brief description of my mapping. and Note that I have some restriction that I need to have the Basket object graph intact

public class Basket {
@OneToMany(fetch = FetchType.LAZY, mappedBy = "basket")
private Set<BasketFruit> basketFruits= new HashSet<BasketFruit>(0);
...
}

public class BasketFruit {
...
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "BASKET_ID")
@ForeignKey(name = "FK_BASKET_FRUIT_BASKET")
private Basket basket;

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "FRUIT_ID")
@ForeignKey(name = "......")
private Fruit fruit;
...
}

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "FRUIT")
public class Fruit {
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "BASKET_FRUIT_ID")
@ForeignKey(name = "FK_FRUIT_BASKET_FRUIT")
private BasketFruit BasketFruit ;
....
}


@Entity
@Table(name = "APPLE")
@PrimaryKeyJoinColumn(name = "FRUIT_ID")
public class Apple extends Fruit{
....
}|
