@Entity
public class Country implements Serializable {
	private static final long serialVersionUID = 1L;
	@Id
	@Column(name="id")
	private int id;
	
	@Column(name="name")
	private String name;
	
	@OneToMany(cascade=CascadeType.ALL)
	@JoinColumn( name="id")
	private Set<State> states;
}
 

 @Entity
@Table(name = "state")
public class State  implements Serializable{
	private static final long serialVersionUID = 1L;

	@Id
	@Column(name = "id")
	private int id;
