Hi,

I am trying to map a one-to-one relation between two classes, but i want to associate a id with a not id column.

these are my two classes:

<class
name="Text"
table="Text">
<id
name="chvp"
column="chvp"
type="integer">
<generator class="identity"/>
</id>
</class>

<class
name="TipoDeContentor"
table="TipoDeContentor">
<id
name="chvp"
column="chvp"
type="integer">
<generator class="foreign">
<param name="property">descricao</param>
</generator>
</id>
<one-to-one
name="descricao"
class="Text"
cascade="all"
constrained="true"/>
</class>


I am trying that TipoDeContentor.descricao (not id) be associated with Text.chvp (id). Is that possible?

When i store a TipoDeContentor object, there are no exceptions, and both classes are stored, but TipoDeContentor.descricao has no value and both IDs have the same key value.

What am i doing wrong?

Thanks in advance,
Joao Rangel

When using one-to-one where the primary keys are not the join then you need to define in the mapping the property reference. This is only in 2.1 and is documented in the 2.1 documentation.

Where can i find hibernate 2.1 documentation?

In the Hibernate 2.1 package.
