Hi,

i have a problem with one-to-many relation.

I always have to store first the child object,
if not do that and try to store the parent with
the child without explicit store the child it
throws a Exception.

Which says SQL insert, update or delete failed (row not found).

Is that not possible that i can store a relation as whole Object,
and the hibernate resolves where he should put the parent and where the
childs.


I will put below my Configuration.xml and the code snip af my store.

<hibernate-mapping>
<class name="net.Schema.enterprise.test.Auftrag" table="Schema.Auftrag">
<id name="auftragnr" column="auftragnr" type="int">
<generator class="sequence">
<param name="sequence">Schema.Auftrag_Seq</param>
</generator>
</id>
<property name="auftragdatum"/>
<property name="auftragtermin"/>
.
..

<set name="auftragattribute" table="Schema.Auftragattribut">
<key column="auftragnr"/>
<one-to-many class="net.Schema.enterprise.test.Auftragattribut"/>
</set>
</class>

<class name="net.Schema.enterprise.test.Auftragattribut" table="Schema.Auftragattribut">
<id name="auftragnr" column="auftragnr" type="int">
<generator class="assigned"/>
</id>
<property name="attributnr"/>
<property name="attribut"/>
.
..

</class>
</hibernate-mapping>

And the save call SNIP.

net.sf.hibernate.Session hiberSess = HibernateUtil.currentSession();
Transaction tx = null;
try{
tx = hiberSess.beginTransaction();
Auftrag auft = new Auftrag();
auft.setAuftragdatum(new Timestamp(System.currentTimeMillis()));
auft.setAuftragtermin(new Date(System.currentTimeMillis()));

.....

Set set = new HashSet();

Auftragattribut att = new Auftragattribut();
att.setExtauftragnr("Ext AuftNR");
att.setAttribut(25);

......

hiberSess.save(att); // ---------------> Without this call it throws the Exception below
set.add(att);

auft.setAuftragattribute(set);
hiberSess.save(auft);
tx.commit();
}catch(HibernateException e)
{
e.printStackTrace();
out.println(e.getMessage());
}

HibernateUtil.closeSession();



Can anyone Help. I hope the description is detailed enough.

Taner.
