Hi,

given:

Code:
public interface A {}
public interface B {}

public class X implements A, B {}


how can i map class X that implements interfaces A and B?
i tried with:

Code:
    <class name="A">
        ...     
        <joined-subclass name="X">
            <key column="A_ID"/>
        </joined-subclass>
        ...
    </class>

    <class name="B">
        ...     
        <joined-subclass name="X">
            <key column="B_ID"/>
        </joined-subclass>
        ...
    </class>


but hibernate complains with a DuplicateMappingException for class X.

what i want (something almost normal, i thing) is a polymorphic association to any object implementing A and/or B.

(btw, the original option was annotations, is this possible with jpa + hibernate annotations?)

thanks.
