Olá Pessoal,
bom estou brincando um pouco com JPA. Porém eu queria ficar evitando de criar classes anemicas que serão as VO e queria trabalhar mais pensando na OO. Então montei minhas classes assim:@Entity
@Table(name="persons")
@Inheritance (strategy=InheritanceType.JOINED)
public class Person {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE)
private Long id;
@Column
private String name;
@Column
private String rg;
@Column
private String email;
private Collection<Official> offial;
public Long getId() {
return id;
}
/* Getters e Setters */
@OneToMany(cascade={CascadeType.ALL},mappedBy="person")
public Collection<Official> getOffial() {
return offial;
}
public void setOffial(Collection<Official> offial) {
this.offial = offial;
}
}
@Entity
@Table(name="officials")
@PrimaryKeyJoinColumn(name="id")
public class Official extends Person {
private EntityManagerFactory factory;
private EntityManager manager;
public Official() {
this.factory = Persistence.createEntityManagerFactory("company");
this.manager = factory.createEntityManager();
}
@Column
private BigDecimal salary;
@Column
private String department;
public void add () {
EntityTransaction transaction = manager.getTransaction();
transaction.begin();
manager.persist(this);
transaction.commit();
manager.close();
}
/* Getters e Setters */
}
Ele hega a gravar as informações na tabela persons mas a de officials ele dá o seguinte erro:

Alguém poderia me ajudar ????? Outra dúvida tem alguma annotation para que na classe official ele ignore as variaveis factory e manager ... pois ele está criando como se fossem campos da minha tabela e na verdade são só para a persistencia ....
Muito obrigado pessoal ....
