After you compile the applet's class definition, simply create an HTML
document with the following in it.

<applet code=MyApplet width=400 height=400>
</applet>

and either load the html file with the appletviewer or a browser.
stewart260@yahoo.com - 20 Oct 2005 02:25 GMT
alright... so now whenever i try to load it, i get an error, the screen
with an x in the top left corner... um, what could be the problem this
time? i compile everything with no errors, my files are all in the same
folder... exc. any ideas?
Thanks for the help
klynn47@comcast.net - 20 Oct 2005 02:32 GMT
Can you post your applet code?
stewart260@yahoo.com - 20 Oct 2005 02:40 GMT
<html>
<body>
<applet code = "brickscreen.class" width = 500 height = 500>
</applet>

</body>
</html>
klynn47@comcast.net - 20 Oct 2005 02:43 GMT
No. I mean the actual applet.

> No. I mean the actual applet.

Of course..  an applet was meant to live in a web-page, so..

A single web page that includes the applet and *links* to
the (short but complete) applet code might be *best*, since
everything is in the same place.  Also, we can see the console
error (or not*) ourselves.

* It might just be the OP's own browser is running
an older Java, and the 1.1 compatible code has been
compiled for 1.5.

See <http://www.physci.org/codes/sscce.jsp#eg>
"Example - Extra Points/Standards on the Internet/
Java Applets" for further details..

hey so if it is the 1.1 compatable vod has been compiled for the 1.5,
how can i fix this?

I am not willing to play the '25 guesses' game with applets
at the moment.  Prepare an SSCCE and post the link - I'll
have a look over the applet and code and get back to you.

You must post code if you expect help. Your comments border on the
unsulting they are so unhelpful. It is hard not to believe you are
toying with us.

um, well, its kindof really long... and there are 4 different classes.
i have run it without error on another computer, so i am guessing the
problem is either with how i was typing it in html, or maybe i dont
have java or something on my computer...
Andrew Thompson - 20 Oct 2005 03:09 GMT

Steps (suggested) to solve this problem.
1) prepare an SSCCE
2) ....
stewart260@yahoo.com - 20 Oct 2005 03:12 GMT
um, whats that? (should i feel stupid)
stewart260@yahoo.com - 20 Oct 2005 03:21 GMT
ok, but wait, if my java creater is 1.1 and my web browser is 1.5 would
that create a problem? or would it be the other way around?
stewart260@yahoo.com - 20 Oct 2005 03:30 GMT
ok well here is the code... i have a brick class, a brickscreen class,
and a dodger class... i realized that in my html file i really called
brickmain instead of brickscreen...
hope this is what you wanted.
Here you go:

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

public class brickmain extends JApplet implements KeyListener
{
private brickscreen displayboard;
private JLabel label;
private JButton startbutton;

public void init()
   {
     displayboard = new brickscreen();
     displayboard.setBackground(Color.blue);
     startbutton = new JButton("Start");
     startbutton.addActionListener (new ButtonListener ());

      label = new JLabel("Test: ");
     Container cp = getContentPane();
      cp.add(startbutton, BorderLayout.NORTH);
    cp.add(displayboard, BorderLayout.CENTER);
    cp.add(label, BorderLayout.SOUTH);
    addKeyListener(this);
}

public void keyPressed(KeyEvent e)
{
int code = e.getKeyCode();

label.setText(Integer.toString(code));

switch(code)
{
case KeyEvent.VK_UP:
displayboard.moveup();
label.setText("It Worked");
break;

case KeyEvent.VK_RIGHT:
displayboard.moveright();
label.setText("It Worked");
break;

case KeyEvent.VK_LEFT:
displayboard.moveleft();
label.setText("It Worked");
break;

}

}

public void keyReleased (KeyEvent e)
{}

public void keyTyped (KeyEvent e)
{}

private class ButtonListener implements ActionListener
{
public void actionPerformed(ActionEvent event)
{
requestFocus ();
displayboard.start();
}
}
}

A lot of the posts that you have made since I posted that
link earler, convince me that you *think* you know what I
am asking for, but did not read the contents of the web page
from start to end.

Please do that, and then you might understand why anything
less than a *single* link to the 'broken applet' web-page
I described earlier, will be completely ignored by me.

And please drop the "i'm so dumb/toe in the sand" posting
style.

Few people would be prepared to continue a conversation with
a poster who refuses to put capital letters at the start of
sentences, or for the words such as "I"/"I'm" *.
I find such text to be quite irritating.

* I am willing to bear with it if English is so difficult
for the poster that they do not understand where to put
full-stops, but in most instances, that is obviously not
the problem.

Try putting the applet class file in the same folder as your html.
Also, Put the other classes used by applet class in the same folder.
Can you post the exact error too.

An "error"???.  That could be ANYTHING. Look the error up at

Well, at least you remember the 2 keywords: html, applet
So go to http://www.google.com and enter:
 html +applet
or better, since you look for a tutorial on these, enter:
 html +applet +tutorial

And just look at the sample html on my website, particularly in
