Hi All,

I've had problem to map a composite key between a Customer class and Phone class in EJB3.

I mapped these classes like shown below and working fine without using EJB3. Therefore when I use these entities in EJB3 and try to retrieve a Customer, the aplication keep a loop until Glassfish turn off through protocol violation.


@Entity
@Table( name="CFGCUSTOM" )
@javax.persistence.SequenceGenerator(
    name="SEQ_CUSTOM",
    sequenceName="SEQ_CUSTO" )
public class Customer extends VObject {
    @Id
    @Column( name="NIDCUST" )
    @GeneratedValue( strategy=GenerationType.SEQUENCE, generator="SEQ_CUSTO" )
    private Long id;
    
    @NotNull
    @Column( name="CNAMECUST")
    private String name;
    
    @OneToMany( mappedBy="id.customer", cascade = { CascadeType.ALL }, fetch=FetchType.EAGER )
    private Set<Phone> phones= new HashSet<Phone>();
    ....
    ....
    ....
}

@Entity
@Table( name="CFGPHONE" )
@AssociationOverride( name="id.customer", joinColumns = { @JoinColumn( name="NIDCUST" ) } )
public class Phone extends VObject {
    @EmbeddedId private PhonePk id;
       
    @NotNull
    @Column( name="CFGNPHONE" )
    private String number
    
    @NotNull
    @Column( name="CTYPEPHONE" )
    private String phoneType;
    ....
    ....
    ....
}

@Embeddable
public class PhonePk implements Serializable {
    @Column( name="NIDPHONE" )
    private Long id;
    
    @ManyToOne( fetch=FetchType.EAGER )
    @JoinColumn( name="NIDCUST" )
    private Customer customer;
    ....
    ....
    ....
}

I read these mappings aren't support in EJB3, but I'm not sure. Do anybody know how to solve it.

Thanks,
Cleiton
