Hallo,

ich möchte innerhalb einer GWT Applikation Dateien von der lokalen Festplatte auf einen WebDAV-Server hochladen...

Dazu verwende ich die Library Sardine...

Die Methoden von Sardine funktionieren für hochladen, erstellen von Verzeichnissen aus einem Standalone Programm (main-Methode) einwandfrei.

Leider funktioniert das gleiche nicht mit GWT. Probiere schon nun seit viiiiiiieeeelen Stunden ohne Erfolg!

Ich weiss nicht wie ich die AccesControlException aushebeln könnte

Wäre um jeden Hinweis sehr dankbar!

Code :

Der Fehler resultiert aus den Einschränkungen der Google App Engine...

es gibt eine Möglichkeit, indem man die SecurityProvider Klasse überschreibt. Das ist nicht so schwierig!
