> I subclass Customer that has a EmbeddedId using JOIN inheritance strategy. My embeddable class has @ManyToOne relationship. Look the classes:
> Pesson class:
> @Entity
> @Table(name="person")
> public class Person {
>    @Id
>    private Integer personId;
>    private String name;
> }   
> Embeddable class ID.
> @Embeddable
> public class PersonPk implements Serializable {
>    @ManyToOne(optional=false,
>            cascade={CascadeType.PERSIST,
>            CascadeType.REFRESH,
>            CascadeType.REMOVE}, fetch=FetchType.EAGER)
>    @JoinColumn(name="personId")
>    private Person person;
>    // ... getters and setters
> } 
> CustomerClass:
> @Entity
> @Table(name="Customer")
> @Inheritance(strategy=InheritanceType.JOINED)
> public class Customer {
>    @Id
>    private PersonPk pk = new PersonPk();
> } 
> Regional Custumer:
> @Entity
> @Table(name="AmericanCustomer")
> @PrimaryKeyJoinColumn(name="personId")
> @IdClass(PessoaPk.class)
> public class AmericanCustomer extends Customer {
>    // some american customer fields..
