Im working with a legacy database and an application written for Apple WebObjects and migrating it to Hibernate.

I'm trying to map a many to one relationship and its join column as a property. But Hibernate gives "Repeated column in mapping" error if i try to do that, unless i make one of them readonly with insert=false and update=false.

But the application written in WebObjects requires both to be writable. Is there any way around this?

Example:

<class name="Student" table="students">

<property name="deptCode" column="dept_code" type="string">

<many-to-one name="department" class="Department">
<column name="dept_code"/>
</many-to-one>

</class>
