Habe mich heute das erste Mal an Insert Statements getraut und prompt gibts einen Fehler ;-)
Habe folgendes einfaches Beispiel:
Code:
public void InsertTest() throws Exception {
Session session = HibernateUtil.currentSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
EtTest test = new EtTest();
test.setText("Test");
session.saveOrUpdate(test);
tx.commit();
}
catch (Exception ex) {
if (tx != null)
tx.rollback();
msg = bundle.getString("testnachricht");
context.addMessage(null, new FacesMessage(
FacesMessage.SEVERITY_WARN, msg, null));
throw ex;
}
finally {
HibernateUtil.closeSession();
}
}
Das Mapping File dazu:
Code:
<hibernate-mapping schema="EDITOOLS" package="com.magnasteyr.editool.hibernate">
<class name="EtTest" dynamic-update="true" dynamic-insert="true" lazy="false" table="ET_TEST" schema="EDITOOLS">
<id name="id" type="long" unsaved-value="null">
<column name="ID" not-null="true" index="SYS_C0063013" sql-type="NUMBER"/>
<generator class="sequence"/>
</id>
<property name="text" type="string">
<column name="TEXT" sql-type="VARCHAR2"/>
</property>
</class>
</hibernate-mapping>
Wenn ich nun diese Methode ausführe, wird zwar in die Datenbank geschrieben, trotzdem erhalte ich in Eclipse folgende Meldung (Oben seht ihr auch noch das Select Statement, dass ausgeführt wird):
Code:
Hibernate: select EDITOOLS.hibernate_sequence.nextval from dual
Hibernate: /* insert com.magnasteyr.editool.hibernate.EtTest */ insert into EDITOOLS.ET_TEST (TEXT, ID) values (?, ?)
Problem with checked-in Statement, discarding.

Hab ich da irgendwas vergessen?Ich mein, dass is ja jetzt noch ein einfaches Beispiel und trotzdem fliegt er da...Verstehe ned ganz, wo die NullPointerException herkommt.
Bitte um Hilfe!
