applet blank screen

[plasticfood]

i don't know what happened, but i was running an applet that i made on a webpage and it works fine. i have the latest JRE and i am running firefox 4. then i've made some changes to the applet, tested it, it works, and copy and paste the class file to my html folder. i open up the webpage with the applet and it's a white blank. i've tested it on 3 browsers (opera, firefox, and chrome) and it all shows the same result. i have no idea what is wrong b/c it worked before and now it doesn't work...

it's a silly little program, but can somebody test this out for me, and let me know if it works on your browser.

[anantha.sharma]

you've created all the items but not added any of them to the container...

thats why nothing is shown... use

add(<<somecomponent);

you are adding textfields, buttons to panels, you need to add the panel to the main container...

[plasticfood]

can you please elaborate on that because it works fine when i use applet viewer.

update: there's something fundamentally wrong with my code, here's a simple applet i've wrote that a little circle follows your mouse everywhere.

import javax.swing.*;
import java.awt.event.*;
import java.awt.*;


public class Eyes2 extends JApplet{
	
	private int x2 = 198;
	private int y2 = 199;
	private int width2 = 15;
	private int height2 = 15; 
	
	public void init(){
		getContentPane().setBackground(Color.black);
	}
	
	public void paint(Graphics g){
		super.paint(g);
		
		g.setColor(Color.white);
		
		g.fillOval(x2, y2, width2, height2);
		 addMouseListener(new MyMouseListener());

		addMouseMotionListener(new MyMouseMotionListener());

	}
	private class MyMouseListener
                         implements MouseListener
   {
      public void mousePressed(MouseEvent e)
      {
              }

      public void mouseClicked(MouseEvent e)
      {
               
      }

      public void mouseReleased(MouseEvent e)
      {
               }

      public void mouseEntered(MouseEvent e)
      {
			x2 = 198;
			 y2 = 199;
			 repaint(); 
      }

      public void mouseExited(MouseEvent e)
      {
                        x2 = 198;
			 y2 = 199;
			 repaint();           
		}
   }

	   
   private class MyMouseMotionListener
                         implements MouseMotionListener
   {
      public void mouseDragged(MouseEvent e)
      {
      }

      public void mouseMoved(MouseEvent e)
      {
      	          x2 = e.getX();
			y2 = e.getY();	
			
			repaint();
      }
		
		
   }

	
	
	
	
}

when i run this, the circle does not move at all. however this works fine in an applet viewer.
