Nothing happens when I execute a .jar file

Question

Hi all,
When I compile my application in NetBeans, I get a message that says:
{color:red}To run this application from the command line without Ant, try:
java -jar "C:\Documents and Settings\rob\Desktop\Java\Projects\ChapterThreePrograms\dist\ChapterThreePrograms.jar"{color}
However, when I run that command, nothing happens. Any idea what I'm doing wrong? Below is my source code (well, the source code from my text book):
import java.awt.*;
import javax.swing.JFrame;
public class DateClient extends JFrame
  String action;
  boolean firstTime = true;
  int animationPause = 3; // 3 seconds between animations
  Date dateObj; // declare Date object reference
  public void workWithDates( )
    animate( "dateObj reference declared" );
    /***** Add your code here *****/
    /**** 1. Instantiate dateObj using an empty argument list  */
    dateObj = new Date();
    animate( "Instantiated dateObj - empty argument list" );
    /***** 2. Set the month to the month you were born */
    //animate( "Set month to birth month" );
    /***** 3. Set the day to the day of the month you were born */
    //animate( "Set day to birth day" );
    /***** 4. Set the year to the year you were born */
    //animate( "Set year to birth year" );
    /***** 5. Set the day to 32, an illegal value */
    //animate( "Set day to 32" );
    /***** 6. Set the month to 13, an illegal value */
    //animate( "Set month to 13" );
    /***** 7. Assign the value null to dateObj */
    //animate( "Set object reference to null" );
    /***** 8. Attempt to set the month to 1 */
  public DateClient( )
    super( "A Date Object" );
    setSize( 300, 300 );
    setVisible( true );
  public void paint( Graphics g )
    super.paint( g );
    if ( firstTime )
      firstTime = false;
    else
      // display action
      g.drawString( action, 50, 250 );
      // object reference
      int sX = 50, sY = 75;
      int boxL = 75, boxH = 20;
      g.drawRect( sX, sY, boxL, boxH );
      g.drawString( "dateObj", sX, sY - 10 );
      if ( dateObj != null )
        draw( g );
      else
        g.drawString( "null", sX + 15, sY + 15 );
  public void draw( Graphics g )
    int sX = 50, sY = 75;
    int boxL = 75, boxH = 20;
    // arrow
    g.drawLine( sX + boxL, sY + boxH / 2,
                sX + boxL + 25, sY + boxH / 2 );
    g.drawLine( sX + boxL + 25, sY + boxH / 2,
                sX + boxL + 25, sY + boxH * 2 );
    g.drawLine( sX + boxL + 25 - 5, sY + boxH * 2 - 5,
                sX + boxL + 25, sY + boxH * 2 );
    g.drawLine( sX + boxL + 25 + 5, sY + boxH * 2 - 5,
                sX + boxL + 25, sY + boxH * 2 );
    // month
    g.drawString( "month", sX + boxL - 50, sY + 2 * boxH + 15 );
    g.drawRect( sX + boxL, sY + 2 * boxH, boxL, boxH );
    g.drawString( Integer.toString( dateObj.getMonth( ) ),
                   sX + boxL + 5, sY + 2 * boxH + 15 );
    // day
    g.drawString( "day", sX + boxL - 50, sY + 3 * boxH + 15 );
    g.drawRect( sX + boxL, sY + 3 * boxH, boxL, boxH );
    g.drawString( Integer.toString( dateObj.getDay( ) ),
                  sX + boxL + 5, sY + 3 * boxH + 15 );
    // year
    g.drawString( "year", sX + boxL - 50, sY + 4 * boxH + 15 );
    g.drawRect( sX + boxL, sY + 4 * boxH, boxL, boxH );
    g.drawString( Integer.toString( dateObj.getYear( ) ),
                  sX + boxL + 5, sY + 4 * boxH + 15 );
  public void animate( String a )
    action = a;
    repaint( );
    Pause.wait( (double) animationPause );
  public static void main( String [] args )
    DateClient app = new DateClient( );
    app.workWithDates( );
    app.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
}

I noticed that NetBeans was highlighting the very top line of my code and saying "Incorrect Package", so I copied the source files to a different location and just manually compiled them from the command line. I was then able to manually run the program from the command line. Could anyone enlighten me as to what I've done wrong with the "package", and why the program works when I compile and run it manually?
