Collection Bag wtih annotation

hibernate, java

Solution

If you use a `List` as the reference type but do not specify an index number column, you will have an unordered collection with no uniqueness requirement. Yes the list is an ordered collection at the java level, but there is no guarantee across copies of the entity that they have the same order.

@OneToMany
private List<OtherEntity> otherEntities;

That's all!

Problem

I'm watching a good video made by Burt Beckwith http://www.infoq.com/presentations/GORM-Performance he says: "In traditional Hibernate you could map the collection as Bag, which is just a regular Collection with no ordering or uniqueness guarantees" How Can I map this collection with no ordering or uniqueness with annotation? Thanks.
