Incompatible magic value 1008821359

Dear Java friends
The image slideshow applet works on a web browser (hardwired was wright one should use URL for file download for applets) but once uploaded at the server I get the following message:

java.lang.ClassFormatError: Incompatible magic value 1008821359 in class file Imgslides

The applet consists of one single file called Imgslides.class and the netbeans 5.5.1 ide generates four more according some inner classes (called Imgslides$1.class, Imgslides$EventHandler.class, Imgslides$ImageDisplay.class, Imgslides$Img.class). The applet downloads stuff from a folder (called Imagestore) that sits on
the base folder of my web page. The htm tag of the applet is the following:
<applet align="left" code="Imgslides.class" width="350" height="390"></applet> (I uploaded all mentioned classes)
(All this works fine when viewing at several of my macbook web browsers) What is missing here???
