Hi Andrea,

i'm not sure why it gives you the bad magic number, but here is something that explains what
it is.

It seems that your class file isn't recognized by the classloader. Maybe try to create the
jar again?

Kind regards,

Jeroen Reijn

Subject: Signed Applet and Cocoon


Hi all,
I have to integrate an applet into my web application. The 
webapplication code is implemented with cocoon 2.1.9. The applet has to 
be signed. If I copy my package tree into my application directory I can 
start my applet. For signing the applet I have to pack my classes into a 
jar file. But if I try to start my applet archived in a jar file the 
following exception is thrown:
 java.lang.ClassFormatError: package/LoginApplet (Bad magic number)

Is there anybody could give a hint?

Best regards
