components - hbm2java.CodeGenerator

I'm studying "Chapter 6. Components", and I did the the following example:

Code:

<class name="vo.PersonVO" table="person">
      <id name="id" column="id" type="int">
         <generator class="sequence"/>
      </id>
      <property name="birthday" type="date"/>
      <component name="name" class="vo.NamePerson">
         <parent name="person"/> <!-- reference back to the Person -->
         <property name="initial" type="char"/>
         <property name="first" type="string"/>
         <property name="last" type="string"/>
      </component>
   </class>

In this component, I put a <parent> subelement...

Quote:

The <component> element allows a <parent> subelement that maps a property of the component class as a reference back to the containing entity.

When I run the hbm2java.CodeGenerator to generate the class, two classes are generated, the PersonVO and the NamePerson.
Shouldn't the NamePerson class have a property "person" that references the PersonVO ? If not, How can I accomplish that?

Code:

/** @author Hibernate CodeGenerator */
public class NamePerson implements Serializable {

    /** nullable persistent field */
    private char initial;

    /** nullable persistent field */
    private String first;

    /** nullable persistent field */
    private String last;

then, when I run the SchemaExport, the following error happens:

net.sf.hibernate.PropertyNotFoundException: Could not find a setter for property person in class vo.NamePerson...

I think that the NamePerson class needs a property "PersonVO person;", then when I put the "private PersonVO person;" attribute in the NamePerson class, the SchemaExport runs successfully!

am I right?

thanks
