Hallo!
Ich habe ein Applet das mittels JCo Verbindung zu SAP herstellt und
Daten abfragt in Eclipse erstellt. Dort funktioniert es einwandfrei.
Sobald ich dieses Applet aber in eine html-Seite integriere geht es
nicht mehr. Das Applet wird angezeigt, man kann etwas eingeben und
auch ausgeben, jedoch wird JCo nicht mehr gefunden.
In der Konsole erhalte ich folgende Fehlermeldung wenn ich es das
erste Mal versuche:
