Hi,
ich habe ein merkwürdiges Phänomen:
Ich habe eine GUI-Applikation, die ich innerhalb von Eclipse auch prima als Java-Application ausführen kann.
Wenn ich das dann jedoch von der Kommandozeile außerhalb von Eclipse aufrufen möchte,
bekomme ich immer folgende Exception:
Die GUI ist mit dem VE erstellt.
Die GUI-Klasse verwendet JPanel, das allerdings anschließend in einem JFrame hinzugefügt wird.
Muss ich da noch irgendwas beachten? Ich poste hier mal den vom VE erzeugten Code:
Ok, der ist nicht schön, aber aufräumen kann ich erst, wenn das Ding funktionert.
Hier noch eine Main-Classzum Aufruf:
Habt ihr einen Hinweis für mich?
Danke,
Thomas
