@Audited
@MappedSuperclass
public abstract class A implements Serializable
{
private static final long   serialVersionUID    = 1L;

private Timestamp           time;
}

@Entity
@Audited
public class B extends A
{
private static final long               serialVersionUID    = 1L;

@EmbeddedId
private EmbeddedId  embeddedId;

@ManyToOne
@JoinColumn(name = "CODE")
private Code                    code;
}

@Audited
@Embeddable
public class EmbeddedId implements Serializable
{
private static final long                   serialVersionUID    = 1L;

@ManyToOne
@JoinColumn(name = "C") …
