 Post subject: Rückgabewert createQuery = null?

Wann gibt die Methode createQuery für Listen eines Sessionobjektes den Wert null zurück?
Wenn die Tabelle leer ist, gibt es eine Liste zurück. Wenn die Tabelle nicht befunden wird, gibt es eine Exception.
Nun habe ich einen Fall, wo der Rückgabewert null ist. Aber ich weiß nicht, warum. Hat da jemand vielleicht eine Idee?
Kann es irgendwie an der Datenbankverbindung liegen?
