Hello.
It is not clear what exactly does no work? The mapping looks Ok although I would reverse sides and make <one-to-one> element part of Company mapping, not MonthlyFee one...

If you need example with <one-to-one> mapping, take a look at http://www.hibernate.org/45.html

Code:

<hibernate-mapping>
    <class name="Company" table="company">
      <id name="cnpj" column="cnpj">
         <generator class="assigned"/>
      </id>
        <property name="name" column="name"/>
      <property name="address" column="address"/>
      <one-to-one name="monthlyFee" class="MonthlyFee"
         constrained="false" outer-join="false"/>               
    </class>
</hibernate-mapping>


<hibernate-mapping>
    <class name="MonthlyFee" table="monthly_fee">               
        <id name="cnpj" column="cnpj">
           <generator class="foreign"/>
         </id>
        <one-to-one name="company" class="Company" constrained="true" outer-join="auto"/>
        <property name="value" column="valor"/>       
        <property name="dtPayment" column="date_m"/>       
    </class>
</hibernate-mapping>

Key one-to-one does not exist. the DTD is an essential part of the doc.

Thank you very much!!!

I know that the property key-one-to-one does not exists,
but, unfortunately, I did not find an example for this.

thanks again,
