Question

Is it possible to tell JAXB to create Hibernate bidirectional mapping?
Holding class can have many Policy children.
To pass Parent’s PK to Child’s FK, I have to set

policy.setHolding(holding)

and then I can say

session.save(holding)

But it doesn’t work when I am marshalling XML to Holding object using JAXB.

Note: I’m the EclipseLink JAXB (MOXy) lead and a member of the JAXB (JSR-222) expert group.

You may be interested in the @XmlInverseReference extension in EclipseLink JAXB (MOXy) for supporting this use case. Below is an example:

Customer

import javax.persistence.*;

@Entity
public class Customer {

    @Id
    private long id;

    @OneToOne(mappedBy="customer", cascade={CascadeType.ALL})
    private Address address;

}

Address

import javax.persistence.*;
import org.eclipse.persistence.oxm.annotations.*;

@Entity
public class Address implements Serializable {

    @Id
    private long id;

    @OneToOne
    @JoinColumn(name="ID")
    @MapsId
    @XmlInverseReference(mappedBy="address")
    private Customer customer;

}
