Annotations, Class is its own composite key

Hello,

I have a problem with the following schema:

Code:

Class X {
 String a;
 String b;
}

a and b make the class' composite key.

I could work without a problem with that class using a hibernate mapping file.

Code:

<hibernate-mapping>
    <class name="X">
        <composite-id>
            <key-property name="a" type="string">
            </key-property>
            <key-property name="b" type="string">
            </key-property>
        </composite-id>
    </class>
</hibernate-mapping>

When I tried to use annotations instead (starting a move towards ejb3 annotations), I couldn't make it work.

I tried something like
@Entity
@Embeddable
@IdClass(X.class)
public class X

returns:
org.hibernate.AnnotationException: No identifier specified for entity: X

If I add @Id to both properties, I have:
Caused by: org.hibernate.AnnotationException: X has not persistent id property

when creating the annotation configuration instance.

Is this too weird?
I'd like to avoid duplicating the class just to have a PK class...
