Hi My Super class is having Primary key and in my Sub class Entity I want to define/use Sequencer defined in Oracle database but I am always getting value of ID(Primary Key) as 0.It seems sequencer is not getting executed.Please help.

@MappedSuperclass
public abstract class GenericEntity implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@Column(name = "ID")
protected long id;

@Version
protected Integer version = Integer.valueOf(0);

public GenericEntity() {
}

public abstract long getId() ;

public void setId(long id) {
this.id = id;
}

}

Sub Class:

@Entity
@Table(name = "pf_address")
@SequenceGenerator(sequenceName="SEQ_PF_ADDRESS", name = "seq_address", allocationSize=1)
public class Address extends GenericEntity {
private static final long serialVersionUID = 5627302335705194341L;
private String country = "";


@GeneratedValue(generator= "seq_address", strategy = GenerationType.SEQUENCE)
@AttributeOverride(name = "id", column = @Column(name = "ID"))
public long getId() {
return id;
}

return country;
}

public void setCountry(String country) {
this.country = country;
}


}
