Java EE (Java Enterprise Edition) General Discussion

Hello,

I wanted to create a bi-directional @OneToOne. The Verifier mandates that I use a @JoinColumn and not a @Column.

Is this true?

I am using Glassfish RI, the accompanying Java DB (Derby) and the oracle toplink essentials that comes with the j2ee sdk.

There was no problem with using a @Column when it was an Uni Directional relationship. When I declared the fields each other, there were problems.

@Entity
@Table (name = "ORGANIZATION")
public class Organization implements Serializable {

 	@Id
 	@GeneratedValue(strategy=GenerationType.AUTO)
 	@Column(name = "ORGANIZATIONID")
	private int organizationId;

	//Bi directional OneToOne
	@OneToOne(optional=true)
        @Column(name = "ADDRESS")
	private Address address;

@Entity
@Table (name = "ADDRESS")
public class Address implements Serializable {

    private int addressId;

    @Column (name="ORGANIZATION")
    @OneToOne(mappedBy="address", optional=true)
    private Organization getOrganization() {
		return this.organization;
	}
	private void setOrganization(Organization organization) {
		this.setOrganization(organization);
	}

Your help would be very useful.

Thanks in advance,
Rajesh
