Ich habe ein Applet mit Eclipse erstellt:

package gui;
public class MyApplet extends JApplet {

Dieses Applet benötigt zwei externe Jars: proj.jar und firebirdsql-full.jar (jdbc)

Deshalb habe ich den HTML-Code so erstellt, und zwar im selben Ordner wie die Gläser:

<APPLET CODE="gui.MyApplet.class" width="650" height="650" ARCHIVE="proj.jar,myApplet.jar,firebirdsql-full.jar">
    <a href="http://java.com/en/download/index.jsp">Java</a>
</APPLET>

Ich habe auch versucht, die Glasreihenfolge im zu ändernARCHIVE Attribut.

Ich erhalte jedoch weiterhin die folgende Fehlermeldung (in der Java-Konsole):

Exception in thread "thread applet-gui.MyApplet.class-2" java.lang.NoClassDefFoundError: Could not initialize class org.firebirdsql.jdbc.FBDriver

    at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
    at java.lang.Thread.run(Unknown Source)

Vermisse ich etwas?

Bearbeiten:

Irgendwie habe ich beim Debuggen auch ein anderes Stacktrace erhalten:
