A component mapped by two different classes

Assume I have three classes, User, CreditCard and Address. User has a collection of Address objects and CreditCard has a reference to an Address object. I am not supporting shared references, so I am not making Address an entity.

Code:

public class User {
   
   private long id;
   
   private String name;
   
   private Set<Address> homeAddresses=new HashSet<Address>();
   
   private CreditCard creditCard;
//the rest of the class

public class CreditCard {
   
   private long id;
   
   private String owner;
   
   private Address billingAddress;

//rest of class

public class Address {
   private String street;
   private String city;

Here are my mapping files:

Code:

           </component>
        </join>
    </class>
</hibernate-mapping>

        <many-to-one name="payment" class="user.PaymentOption" fetch="select">
            <column name="PAYMENT_ID" />
        </many-to-one>
    </class>
</hibernate-mapping>

I am getting some kind of exception in the sessin factory creation. It tells me that User is un-mapped!
Any ideas? Thank you very much.

Sometimes it can be a case sensitive question. Make sure your class has the proper qualified name in the Java code, and you're not doing some incorrect import.
