taskDate ist das Datum, das als String in der DB liegt.

@orlando11: Die Idee an sich klingt echt klasse, aber ich hab keinen Einfluss darauf, wie die Daten aus der Datenbank ausgelesen werden, weil das Hibernate für mich übernimmt.


Edit sagt: Die Exception wird natürlich nur geworfen, wenn ich in Setter und Getter den Timestamp in einen String bzw. den String in einen Timestamp umwandel...
