Hi,
I'm using Hibernate 2.1.1 on Jonas. I have a very simple class and I want to store objet of it.
The point is that the object I want to save may already be stored in the database, in this case I want to update it. So I though that the saveOrUpdate methode could be the right one.
But I get an HibernateException :

net.sf.hibernate.HibernateException: Batch update row count wrong: 0
I have checked with the methode save by clearing the table before, and it works.
Here is the mappings :
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping
PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping>
<class name="org.enhydra.shark.instancepersistence.data.HibernateProcessState" table="processstates">
<id name="id">
<column name="id" not-null="true"/>
<generator class="increment"/>
</id>
<property name="keyValue">
<column name="keyvalue" not-null="true"/>
</property>
<property name = "name">
<column name="name" not-null="true"/>
</property>
</class>
</hibernate-mapping>
And here is the piece of useful code :
HibernateTransactionFactory hibFact = new HibernateTransactionFactory();
SharkTransaction t = hibFact.createTransaction();
HibernateProcessState hibProcessState = new HibernateProcessState();
HibernateActivityState hibActivityState = new HibernateActivityState();
Session session = ThreadLocalSession.currentSession();
for (int i=0; i<1/*activityAndProcessStates.length*/; i++) {
String state=activityAndProcessStates[i];
System.out.println("hibProcessState " + i + "= " + state);
hibProcessState.setKeyValue(state);
hibProcessState.setName(state);
session.saveOrUpdate(hibProcessState);
}
t.commit();
session.close();
Here is the POJO class :
public class HibernateProcessState {
private String keyValue;
private String name;
private int id;
public HibernateProcessState() {
}
public String getKeyValue() {
return keyValue;
}
public String getName() {
return name;
}
public void setKeyValue(String string) {
keyValue = string;
}
public void setName(String string) {
name = string;
}
public int getId() {
return id;
}
public void setId(int i) {
id = i;
}
}
Any idea, I saw that unsaved-value is important and by default check the identifier. But I think my problem is a little bit more complicated. The id is generated by incrementing the existing and last value in the DB table, but when I will try to saveOrUpdate the object, there have not yet id set.
