Hi,

I have an object model that looks like: Person->A->*B. However I have only two tables: Person, and B, with B having a foreign key pointing back to Person.

So, object A's attributes reside inside the Person table. Therefore I'm making A a component of Person.

Now I would like to form a bidirectional relationship between objects A and B (one-to-many). That would force B's mapping file to reference A, which is a component.

1. The component mapping for A looks like:

<component
name="a"
class="*.*.*.A">

....
<set
name="setOfBs"
lazy="false"
inverse="true"
cascade="all">
<key column="PERSON_ID" />
<one-to-many class="*.*.*.B" />
</set>
.....
</component>

2. B's mapping looks like:
...
<many-to-one
name="a"
class="*.*.*.A"
column="PERSON_ID"
not-null="true"
insert="true"
update="false"
/>
...

Now when I try to test this, I get:

"An association from the table B refers to an unmapped class: *.*.*.A"

Please advise as for how I can make this right?

Thanks!

You can't map to components using the many-to-one or one-to-many. Components are different from entities and have their own mapping notation. To see how to map components, or how to map to a collection of components see:
