Guten Morgen Honow,

wenn dein Programm als Java Application laufen soll, solltest du "Reiter Run – Run As – Java
Application" nehmen. Denn ein Java-Applet ist ein eig ein Programm für den Web-Browser.

Hoffe ich habe geholfen

MFG

Lade bitte deine Screen-Shots demnächst über die Anhangs-Funktion hier dierekt im Forum hoch.
Das Problem mit Fremdhostern ist das die Bilder irgendwann gelöscht werden und später niemand mehr Zugriff darauf hat.
Ich habe das mal für dich erledigt.

Hallo, Schinni999

Danke erstmal für deine Antwort, ich hab es als java application durchlaufen lassen, aber mir wurde gefragt, welchen Typ von Application ich auswählen sollte ...wie mach ich weiter ?

Danke, MFG

Hi,

also so wie es dir Schinni999 beschrieben hat funktioniert das schon. Wenn du "Reiter Run – Run As – Java
Application" ausgewählt und gedrückt hast, wird deine Application ausgeführt.
Damit dein Programm gestartet werden kann, muss dieses eine main-Methode enthalten!

Code java:

1 2 3

public static void main(String[] args) {   }

Ohne die funktioniert das sonst nicht, da das der Einstiegspunkt in ein Programm ist.

Gruß

Fabio

Danke euch, es hat geklappt

Nun jetzt hab ich nach dem Ausführen noch ne Fehlermeldung bekommen, wie sollte ich das Problem beheben ? Danke !

Das hilft uns so überhaupt nicht weiter. Du musst auch den relevanten Code preisgeben. Sonst können wir auch nur raten.

Eclipse zeigte mir nur den einzigen Fehler, aber ich glaube ich hab die Datenbank schon in den ODBC-Quellen eingetragen..weiß gerade nicht warum ..

Wie schon gesagt, ohne Code können wir dir nicht helfen...

ah, sorry ich füge gleich hier die Code hinzu..

Bitte verwende die Java-Codetags. Da da der Code gehighlighted wird.

Ok, sorry nochmal

Hi.

Zitat von hanow

Code :

1	java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Datei '(unbekannt)' nicht gefunden.

Das heißt einfach nur, das die Datenbank-Datei, die du in deinem Connection-String angegeben hast bzw. als Datenquelle in ODBC eingetragen hast, nicht gefunden werden konnte.

Bitte verwende für Code keine Zitat-Tags. Danke.

Gruß

Danke, ich brauch Vorschlag, wie kann ich am besten das Problem beheben ?

Trag die Datei als ODBC Quelle ein bzw. berichtige den Connection String.

Du hast doch Zugriffsrechte auf die Datei / das Verzeichnis in dem die Datei liegt?

Zeige den Connection String. Wo liegt die Datenbank-Datei?

Gruß
