Wenn ich ein JAR erstelle und die Zeilen 232 + 233 auskommentiere funktioniert alles super, mit den Zeilen bekomme ich folgende Fehlermeldung, wenn ich das JAR ausführe: "Could not find the main class. Program will exit."
Was ist denn an diesen Zeilen falsch??? Wenn ich meinen Code in der Programmierumgebung starte funktioniert alles ohne Fehler.

Danke

..vielleicht findet er OutputFrame nicht ? ...

 

[chrissy]

Dann würde er doch aber schon bei

output1 = new OutputFrame()

hängen und in der Programmierumgebung auch nicht laufen, oder?

Den Fehler habe ich auch manchmal. Ich weis leider nicht mehr genau, wie ich ihn behebe...
Ich glaube es lag an der Manifest (ich glaube die leeere Zeile am Ende fehlt).
Überprüfe noch mal deine manifest-Datei (Leere Zeile am Ende, Korrekte Schreibweise etc.).

Danke, das war's ...
