Hallo! Ich habe ein JSF-Formular. Die eingegebenen Daten sollen gespeichert werden. Dabei treten leider folgende Fehler auf. Ich hoffe hier kann mir jemand helfen.

java.lang.ExceptionInInitializerError
beans.UserHandler.processAction(UserHandler.java:32)
javax.faces.event.ActionEvent.processListener(ActionEvent.java:51)

org.apache.myfaces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:70)
javax.faces.webapp.FacesServlet.service(FacesServlet.java:139)

Meine action-methode wo der das speichern geschehe soll sieht so aus:
public void processAction(ActionEvent ae) throws AbortProcessingException {
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
Transaction trans = session.beginTransaction();
session.save(user);
trans.commit();
session.close();
}

ich habe eine SQL-DB angelegt. Die Spalten der Tabelle sond so eingestellt, das sie nicht null sein können. Wenn ich not null rausnehme, dann wird in alle Spalten der Tabelle der wert null eingetragen....

beim mappen dürfte eigentlich kein fehler aufgetereten sein. constarint hat ja eigentlich was mit wertebeschränkung zu tun. Da steht ja column betriebsmittel cannot be null. soll sie ja auch nicht...

kann da jemand was zu sagen?

Das Objekt der Klasse, die Du speicherst hat Null in den Attributen stehen.
