I have a parent table Employee and a child table Employee_Address

Primary key of Parent empId
Composite key of child empAddressId and accountNumber

Parent table has accountNumber as a column
Child table has empId as a column

I am unable to set one-tomany association in this scenario

Here is my Employee (PARENT) mapping file

<hibernate-mapping>
<class name="Employee" table="EMPLOYEE">
<id name="empId" type="long">
<column name="EMP_ID" precision="15" scale="0" />
<generator class="assigned" />
</id>
<property name="acctNo" type="string">
<column name="ACCT_NO" length="5" not-null="true" />
</property>


<set name="empAddresses" inverse="true" lazy="true">
<key>
<column name="empId"/>

</key>
<one-to-many class="EmpAddress" />
</set>

</class>
</hibernate-mapping>


Java BEAn for Employee is very standard with all the getters/setters


EmployeeAddress (CHILD) mapping file:

<hibernate-mapping>
<class name="EmpAddress" table="POL_INT_ADDRESS">


<composite-id name="id" class="EmpAddressKey">
<key-property name="addressId"/>
<key-property name="acctNo"/>
<key-property name="empId"/>
</composite-id>


<many-to-one name="emp" class="Employee" insert="false" update="false" fetch="join">
<column name="empId"/>
</many-to-one>
<property name="xval" type="long">
<column name="X_VAL" precision="15" scale="0" not-null="true" />
</property>
<property name="yVal" type="int">
<column name="Y_VAL" not-null="true" />
</property>
</class>
</hibernate-mapping>


Java code for the composite key EmpAddresskey
public class EmpAddressKey implements Serializable{


private String acctNo;
private long empAddressId;
private long empId;

public EmpAddressKey(long empAddressId, String acctNo, long empId) {
///intialize parametrs
}

//getters/setters for empAddressId, empId, acctNo

//equals and has code methods also implemented

}


When I run Session.load(Employee)...I get the result set for Employee (PARENT ) table but the collections size for EmpAddress is Zero.


Can someone point me in right direction. Anything wrong with the mapping???
I get Error:could not load an entity: [Employee#1234]
