> This article published on the O'Reilly web site - http://onjava.com/pub/a/onjava/2005/08/03/hibernate.html?page=3 - describes how to implement joins with formulas, using the hbm xml files. We should be able to do the same with annotations: 
> <hibernate-mapping>
>   <class name="Company" table="Company">
>     <id name="id" />
>     <many-to-one 
>       name="defaultContactPerson" 
>       property-ref="defaultContactPerson">
>         <column name="id"/>
>         <formula>1</formula>
>         </many-to-one>
>   </class>
>   <class name="Person" >
>     <id name="id" />
>     <properties name="defaultContactPerson">
>         <property name="companyID" />
>         <property name="defaultFlag" />
>     </properties>
>   </class>
> </hibernate-mapping>
