I have developed an application in eclipse using the processing libraries, in essence

I have a processing class which contains the following:

1. public class Example extends PApplet
2. {
3.       public static void main(String args[]){
               PApplet.main(new String [] { "sim.Simulation" } );
         }
   }

Thus making it an application not an applet, in this class "Example" I also used various other normal java classes and swing guis. What i am trying to say is that this project is using quite a lot of everything.

When I export to a jar I get the error:
