>  I have 2 classes viz. Product and ProductBasic having one-to-one relationship
>   
>   class Product{
>    String productId;
>    ProductBasic productBasic;
>    }
>    
>    class ProductBasic{
>     String productId;
>     String useCode;
>     TimeStamp startTime;
>    
>     Product product;
>    }
>    
>    Product is mapped to a table PRODUCT which has PRODUCTID as PK.
>    ProductBasic is mapped to a table PRODUCTBASIC which has PRODUCTID,USECODE and STARTTTIME as composite key. 
>    Also PRODUCTID (of PRODUCTBASIC table) is the foreign key referencing PRODUCT table...
>    
>   How can i define my one-to-one mapping considering ProductBasic.productId should get its value from Product.productId ?
>   
>   
>   <composite-id>
>     <key-property name="productId" column="PRODUCTID" type="string" length="10" />
>     <key-property name="useCode" column="USECODE" type="string" length="10" />
>     <key-property name="startTime" column="STARTTIME" />
>   <composite-id>
>   
>   In this only productId is the foreign key..
>   
>   I am aware that i can use a <generator> tag (with class="foreign") inside <composite-id> but i guess it will generate the
>   value for entire composite-id and not just a field of it.
