Hello all.  I have a very simple problem.  I am seeking to develop
java apps on mepis linux (ver. 3.4-3).  I have installed jdk 1.6.0 and
i am having runtime error problems.  It seems like a simple matter,
but i do not know how to solve the problem i am having.  I have
compiled the following code directly from the sun website...

package start;

/*
* HelloWorldSwing.java requires no other files.
*/
import javax.swing.*;

public class HelloWorldSwing {
   /**
    * Create the GUI and show it.  For thread safety,
    * this method should be invoked from the
    * event-dispatching thread.
    */
   private static void createAndShowGUI() {
       //Create and set up the window.
       JFrame frame = new JFrame("HelloWorldSwing");
       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

       //Add the ubiquitous "Hello World" label.
       JLabel label = new JLabel("Hello World");
       frame.getContentPane().add(label);

       //Display the window.
       frame.pack();
       frame.setVisible(true);
   }

   public static void main(String[] args) {
       //Schedule a job for the event-dispatching thread:
       //creating and showing this application's GUI.
       javax.swing.SwingUtilities.invokeLater(new Runnable() {
           public void run() {
               createAndShowGUI();
           }
       });
   }

}

when i compile, nothing seems to be wrong...

Aesotericon@5[HelloWorldSwing]$ ls
HelloWorldSwing.java
Aesotericon@5[HelloWorldSwing]$ /home/Aesotericon/Documents/jdk1.6.0/
bin/javac HelloWorldSwing.java
Aesotericon@5[HelloWorldSwing]$ ls
HelloWorldSwing$1.class  HelloWorldSwing.class  HelloWorldSwing.java
Aesotericon@5[HelloWorldSwing]$

when i try to run the program the following happens...

Aesotericon@5[HelloWorldSwing]$ /home/Aesotericon/Documents/jdk1.6.0/

As you all see, I have tried several methods of running the program,
but it will not work.  I feel like a simpleton, but does anyone have
any suggestions? It seems that java is having a hard time finding
my .class file.  I dunno...
