Incompatible magic value 218774561 error in applet

Hi Guys,

This is my first post here, but I have been working with Java for some time now. I am working on putting a couple programs I made on my personal website as applets. I uploaded all the .class files to the web server, but when I go to the website to view the applet, I get this error:


Java Plug-in 1.6.0_25

Several searches led me to this forum to a thread that apparently no longer exists. I thought I would ask here as I continue my search. "EditorGUI" is the class that extends JApplet and contains the init() method. All the .class files are in a folder called "editor", which is also the package name for my program's source files. I use Eclipse IDE, and have verified that the applet works using the applet viewer in Eclipse.

I appreciate any help you can offer.
