a complex one-to-one problem

[Dekel Yaacov]

Hi All,
I'm having a problem defining one-to-one.
I have 4 objects:
1.Manager
2. Employee
3. Customer

4. Address

Each of the objects 1-3 has a column called Address_Id and it supposed
to load (or create new) the address from the ADDRESS table.

How do I specify in my mapping files that the column Address_Id is
actually the pk called Id in the Address class/table?

many thanks
D

import javax.persistence.*;    
@Entity
@Table(name="manager")
class Manager{
Address address;
@OneToOne(cascade = CascadeType.ALL)
@PrimaryKeyJoinColumn
public Address getAddress() {
    return address;
}
 
}
@Entity
@Table(name="employee")
class Employee{
Address address;
@OneToOne(cascade = CascadeType.ALL)
@PrimaryKeyJoinColumn
public Address getAddress() {
    return address;
}
 
}
 

@Entity
@Table(name="customer")
class Customer{
Address address;
@OneToOne(cascade = CascadeType.ALL)
@PrimaryKeyJoinColumn
public Address getAddress() {
    return address;
}
}
 

class Address {
Integer id
@Id @GeneratedValue(strategy=GenerationType.AUTO)
    public Integer getId() {
        return id;
    }
}

Hopefully it works for you!
