Datum in Java

[Macs]

Hallo,

ich habe mit Netbeans ein Formula erstellt, in welches ich Daten eingeben kann, die in der Derby Datenbank gespeichert werden.
Soweit klappt es auch, nur für das Feld "Datum" klappt es nicht. Ich gebe ein Datum ein und er übernimmt es nicht in die Datenbank. Ich vermute ich gebe das Datum im falschen Format ein.

Netbeans hatte für mich automatisch folgende Zeilen generiert:

 @Column(name = "DATE1")
    @Temporal(TemporalType.DATE)
    private Date date1;


public void setDate1(Date date1) {
        Date oldDate1 = this.date1;
        this.date1 = date1;
        changeSupport.firePropertyChange("date1", oldDate1, date1);

Wenn ich ein Datum direkt über SQL in die Datenbank schreibe, klappt natürlich.

Hallo,

ist dein Date von java.util.Date oder von java.sql.Date?

Die Frage kam mir auch erst, aber da NetBeans diese Zeilen generiert hat, war ich mal davon ausgegangen, dass die richtigen Pakete importiert wurden.

Gibt es denn irgendwelche Fehlermeldungen? "klappt nicht" ist immer so unpraezis...

hi,
er importiert java.util.Date.
