    Default Unable to view applets on a web browser

    Hi i'm a newbie and i tried that hello world example except that i renamed it to HelloApplet.java . I tried to view it on a html page using hotjava 3.0 and i get these exceptions when i do

    PHP Code:
    ?HelloApplet.class?:
    
    
    java.lang.ClassNotFoundException: ?HelloApplet.class?
    
    	at sunw.hotjava.applet.BasicAppletManager.createApplet(BasicAppletManager.java:245)
    
    	at sunw.hotjava.applet.BrowserAppletManager.createApplet(BrowserAppletManager.java:109)
    
    	at sunw.hotjava.applet.AppletPanel.runLoader(AppletPanel.java:480)
    
    	at sunw.hotjava.applet.AppletPanel.processEvent(AppletPanel.java:338)
    
    	at sunw.hotjava.applet.AppletPanel.run(AppletPanel.java:323)
    
    	at java.lang.Thread.run(Thread.java:466)
    My HTML document looks like this (html.html)

    PHP Code:
    <HTML>
    <HEAD>
    <TITLE>This page has an applet on it</TITLE>
    </HEAD>
    <BODY>
    <P>My second Java applet says:
    <BR>
    <APPLET CODE = HelloApplet.class WIDTH=200 HEIGHT=50>
    There would be an applet here if your browser
    supported Java.
    </APPLET>
    </BODY>
    </HTML>
    And my HelloApplet.java :

    PHP Code:
    /* 
    By Bavo Bruylandt (Http://www.realapplets.com") 
    */ 
    
    // and now The inevidable "Hello World" example :) 
    
    // tell the compiler where to find the methods you will use. 
    // required when you create an applet 
    import java.applet.*; 
    // required to paint on screen 
    import java.awt.*; 
      
    
    // the start of an applet - HelloWorld will be the executable class 
    // Extends applet means that you will build the code on the standard Applet class 
    public class HelloApplet extends Applet 
    { 
    
    // The method that will be automatically called  when the applet is started 
         public void init() 
         { 
     // It is required but does not need anything. 
         } 
      
    
    // This method gets called when the applet is terminated 
    // That's when the user goes to another page or exits the browser. 
         public void stop() 
         { 
         // no actions needed here now. 
         } 
      
    
    // The standard method that you have to use to paint things on screen 
    // This overrides the empty Applet method, you can't called it "display" for example. 
    
         public void paint(Graphics g) 
         { 
     //method to draw text on screen 
     // String first, then x and y coordinate. 
          g.drawString("Hey hey hey",20,20); 
          g.drawString("Hellooow World",20,40); 
    
         } 
    
    } 
      
    
    // That's it. Next is drawing special shapes on screen and using fonts. 
    // Go to DrawExample.java.
    I compiled HelloApplet.java on Forte for Java 4.0 CE

    All files i.e HelloApplet.java , HelloApplet.class and html.html are in the same directory i.e C:\forte_jdk\forte4j\bin\ide-userdir\sampledir

    Could someone pls tell me where i went wrong ...
