I have a basic skeleton here and I am finding it really tough to map Polymorphic Queries with annotations. Provided that I have a location field in each item type (offence and defence) How would I go about bidirectionally mapping this query, or even unidirectionally for that matter?

I really appreciate any help, mixing all of this together for such an exotic mapping is really tough to figure out. The following is the basic structure which I've got (which i hope is right)

@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
interface item {
}

@Entity
@Table("Defence")
class Defence implements Inventoryable, Wearable {
..
}

@Entity
@NamedQuery(name = "ClosetItems", query = 'Select * from Inventoryable where location = "INVENTORY"')
class Inventory implements Location {
....
Set<Inventoryable> getItems() {
}
