Liebe Hibernate Community,
Villeicht erscheint meine Frage für einen oder anderen zu einfach, aber leider habe ich noch keine Antwort beim googlen darauf gefunden.

Frage:
Wie soll eine Hibernate Mapping Datei für folgende POJO aussehen? Ich habe insbesonders das Problemm beim der Definition eines SortedSet's welcher primitive Datentyp Werte enthält.
Code:
package hibernate.primitive.type;

import java.util.SortedSet;

/**
* how to map this bean to the hibernate?
* @author Andreas Hollmann
*
*/
public class MyBean{
   private long id;
   private String description;
   private SortedSet<Long> values;
   
   /**
    * constructor
    */
   public MyBean() {
      super();
   }
   
   public long getId() {
      return id;
   }

   private void setId(long id) {
      this.id = id;
   }


   public String getDescription() {
      return description;
   }
   public void setDescription(String description) {
      this.description = description;
   }
   public SortedSet<Long> getValues() {
      return values;
   }
   
   private void setValues(SortedSet<Long> values) {
      this.values = values;
   }
   
}


und das ist mapping Datei wie ich sie mir vorstelle. An einer Stelle weiß ich nicht mehr weiter, ich habe diese Stelle mit einem Kommentar versehen:
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
   "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
   "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="hibernate.primitive.type">
   <class name="MyBean">
        <id name="id" column="id" type="long">
            <generator class="native"/>
        </id>
      <property name="description"    column="description"    type="string"/>      
      
      <set name="values" lazy="true" cascade="all,delete-orphan" inverse="false" sort="natural">
         was soll hier stehen?
       </set>
       
   </class>
</hibernate-mapping>
