I have yet an othe rmapping question. Any help is greatly appreciated.

I have a table Student and two java classes(Student & Person)

Table-Student (name,age,ssn,FatherID,FatherName,MotherId,MotherName)


Public Class Student {

Sring name..

Parent father
Parent mother
...
..
}


Public Class Parent{
String id
String name
}


Question-
I want to use a composite for mapping Parent .
How do I use the same composite for both mother and father?


This is a simplified case of an earlier question I was asking.
Again thanks a lot for all the help and support from this forum.
