This is Parent, Person:

<set name="employers" table="EMPLOYER" cascade="save-update"  inverse="true" lazy="true">
      <key column="ssn"/>
      <one-to-many class="org.xxx.Employer"/>
   </set>

This is Child, Employer:

   <many-to-one name="Person"
       column="SSN"
       not-null="true"
       class="org.xxx.Person"/>

and Employer.java

private String ssn;
private Person person;

/*
*This returns null, but I want to keep it this way if possible.
*/
public String getSsn(){
return ssn;
}

/*
* This works, but SSN is from after referencing the parent object.
*/
public String getSsn(){
return person.getSsn();
}

child.getSSN(); // returns null.
child.getPerson().getSSN(); //returns correct SSN, its coming from parent.


But I want to make this

child.getSSN(); //getSSN(){return ssn;}

to work too. without modify getSSN() method
