Hi All,

This is a Basic JPA program of one to one mapping Here when i am running the program Primary key of Customer class i.e cid is 1 But ID of Address i.e aid and F.K sid is 2 I want aid and sid to be 1 instead of 2

This is main class

public class Hibernate {

public static void main(String[] args) {
Configuration cfg=new Configuration();
cfg.configure("hibernate.cfg.xml");
SessionFactory sf=cfg.buildSessionFactory();
Session se=sf.openSession();
Transaction tx=se.beginTransaction();
Customer c=new Customer();
c.setCname("srikant");
Address a=new Address();
a.setState("karnatka");
c.setAdd(a);
se.save(c);
tx.commit();
}}




@Entity
@Table(name="Cust")
public class Customer {

@Id
  @GeneratedValue
  @Column(name="cid")
  private int cid;

  private String cname;

  @OneToOne(cascade=CascadeType.ALL)
  @JoinColumn(name="sid") // Foreign Key
  private Address add;
  public int getCid() {
  return cid;
  }
  public void setCid(int cid) {
  this.cid = cid;
  }
  public String getCname() {
   return cname;
  }
    public void setCname(String cname) {
    this.cname = cname;
    }
    public Address getAdd() {
    return add;
    }
     public void setAdd(Address add) {
    this.add = add;
     }
    @Override
    public String toString() {
     return "Customer [cid=" + cid + ", cname=" + cname + ", add=" + add +
      "]";
}




  My Address Class

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

   private int aid;
   private String state;
   @Id
    @GeneratedValue
    public int getAid() {
    return aid;
     }
    public void setAid(int aid) {
    this.aid = aid;
   }
    public String getState() {
  return state;
     }
   public void setState(String state) {
    this.state = state;
   }

   @Override
   public String toString() {
    return "Address [aid=" + aid + ", state=" + state +  "]";
      }


         }
