Hi,

I want to use @IdClass to define associations between classes instead of using the concrete class and it should hopefully work with HQL as the normal mapping (#2)


#1
Code:
@Entity
@IdClass(ZonePk.class)
class Zone {
}

@Entity
class Area {
    @ManyToOne
    ZonePk zone;
}




The following use of the concrete class has certain disadvantages (serialisation of proxy, jaxb, etc).

#2
Code:
@Entity
class Area {
    @ManyToOne
    Zone zone;
}



-Tim
