Hallo an die Community !
Ich habe meine erste Applikation nun mit Hibernate angefangen und habe auch gleich mal ein kleines Problem. Ich benutze folgendes:
Hibernate version: 3.2 beta 8
Java Version 1.4
Mapping documents:
TableOriginalManu.hbm.xml:
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="com.***.ma.hibernate">
<class name="TableOriginalManu" table="TABLE_ORIGINAL_MANU">
<id name ="id" column="ID" >
<generator class="native">
</generator>
</id>
</class>
</hibernate-mapping>
TManu.hbm.xml:
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="com.***.ma.hibernate">
<class name="TManu" table="T_MANU">
<id name ="id" column="ID" >
<generator class="native">
</generator>
</id>
<property name ="originalId" column ="ORIGINAL_ID" type ="long" />
</class>
</hibernate-mapping>
Code:
Session s = HibernateUtil.currentSession();
Transaction tx= s.beginTransaction();
// Hole die id des gewählten Datensatzes aus dem request
Long loId = new Long(id);
// Speicherung des Original Datensatzes von T_Manu
// nach Table_Original_Manu.
TManu ma = (TManu) s.load(TManu.class, loId); <-- Lade ma Objekt mit der loID
TableOriginalManu ori = new TableOriginalManu(); <-- Erzeuge neues ori Objekt
ori.setOriginalId(loId); <-- und setze oriID gleich loID
s.saveOrUpdate(ori);
// Speichere in TManu die geänderten Kennzahlen
ma.setOriginalId(ori.getId()); <-- Hier bricht er ab mit der Fehlermeldung
s.saveOrUpdate(ma);
tx.commit();
Und dabei erhalte ich folgende Fehlermeldung:
Code:

Ich benutze die Oracle Datenbank 9i
Außerdem habe ich hibernate.cglib.use_reflection_optimizer auf false gesetzt!
Hat mir vielleicht jemand sagen was ich da falsch mache?
