Running application from jar file in a PDE project?

Question

I have a jar file with a simple application:
import javax.swing.*;
public class MyTest {
  public void test(){
    JOptionPane jp = new JOptionPane();
    jp.showInputDialog("Bob");
  public static void main(String[] args) {
    MyTest m = new MyTest();
    m.test();   
}I have made the Hello World PDE Project in Eclipse on Vista. From the execute function I do:
      * the command has been executed, so extract extract the needed information
      * from the application context.
     public Object execute(ExecutionEvent event) throws ExecutionException {
//          IWorkbenchWindow window = HandlerUtil.getActiveWorkbenchWindowChecked(event);
//          MessageDialog.openInformation(window.getShell(), "MyPlugin", "Hello, Eclipse world");
       MyTest m = new MyTest();
       m.test();
          return null;
     }But nothing happens. I have added the external Jar file to the build path. Any ideas?

I have tried running a debugger but I just get:
"Source not found"
when stepping over this line:
     MyTest m = new MyTest();
I have not been able to find any pages on google that describes this problem or how to use external jars with a PDE project so any ideas are most welcome!
