Table 1 : EmpData
Emp_id Number(5);
Amend_CNT Number(5)
Address VARCHAR(100)

Here Primary Key is Emp_Id, Amend_CNT. now Child Table is
Child Table : EmpContact
Emp_id Number(5);
Amend_CNT Number(5)
Contact_No Number(10)

hibernate :
public EmpContact() {
private EmpData empData;
private String address;
}

in this table Emp_id and Amend_CNT is a foreign Key which reference of Table1:


code :
EmpData emp = new EmpData();
emp.setEmpId(1);
emp.setAmendCnt(1);
emp.setAddress("Bangalore");

EmpContact cnt1 - new EmpContact()
cnt1 .setEmpData(emp)
cnt1.setContactNo(99999999);
emp.getEmpContact().add(cnt1);

EmpContact cnt2 - new EmpContact()
cnt2.setEmpData(emp)
cnt2.setContactNo(00000000);

emp.getEmpContact().add(cnt2);

session.save(emp );
session.flush();
session.refresh(emp );

in the above code data get written in EmpData . but in the child table EmpContact data not written.

Please Help me to solve this problem
