JPAContainer set relationship through programmatically?
Question
I've two entities and I'm using JPAContainer but I don't know how can use to do a relationship with these 2 entities.
here my code
@Entity
@Table(name="curriculum")
public class Curriculum implements Serializable{
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue
private Long idCurriculum;
@Temporal(TemporalType.DATE)
private Date dataCad;
@Size(min=5, max=50)
@NotNull
@NotEmpty
private String nome;
@NotEmpty
private String sexo;
@Email
@NotEmpty
@NotNull
@Size(max=250)
@Column(unique=true)
private String email;
@NotNull
@NotEmpty
@Size(min=14, max=14)
@Column(unique=true)
private String cpf;
}
@Entity
@Table(name="curriculum2")
public class Curriculum2 implements Serializable{
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue
private Long idC2; //NOT NULL AUTO_INCREMENT,
@NotNull @OneToOne @JoinColumn(name="cpf")
private Curriculum curriculum; //NOT NULL,
@NotNull @Temporal(TemporalType.DATE)
private Date dataNasceu; //NOT NULL,
@NotNull @NotEmpty @Size(min=5, max=50)
private String cidade; //` varchar(50) NOT NULL,
@NotNull @NotEmpty @Size(min=5, max=50)
private String endereco; //` varchar(50) NOT NULL,
@NotNull
private int numero; //` int(11) NOT NULL,
