this is the mapping that i built
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping>
<class name="Inventory.Sell" table="Sell">
<id name="Id_Sell" type="integer">
<column name="Id_Sell" />
<generator class="identity" />
</id>
<property name="FechaPedido" type="date">
<column name="FechaPedido" />
</property>
<many-to-one name="Id_Cliente" class="Inventory.Client" >
<column name="Id_Cliente" not-null="false" />
</many-to-one>
<many-to-one name="Id_Employment" class="Inventory.Employment" >
<column name="Id_Employment" not-null="false" />
</many-to-one>
