Problem with creating an applet

Hello everyone,

For a test with applets I wanted to create an applet.

The applet code:
import javax.swing.*;
import java.awt.*;

public class ByeWorld extends JApplet {

public void init() {
Container contentPane = getContentPane();
JLabel label = new JLabel("Goodbye world",SwingConstants.CENTER);
contentPane.add(label);
}
}

The HTML file:
<html>
<head>
<title>Test</title>
</head>

<body>
<applet code="ByeWorld.class" width="200" height="300"></applet><br />
Hieronder staat een test met een applet
</body>
</html>

At running of the applet I get the following exception:

Exception in thread "Thread-6" java.lang.IllegalArgumentException
at sun.net.www.ParseUtil.decode(Unknown Source)
at sun.net.www.protocol.file.Handler.openConnection(Unknown Source)
at sun.net.www.protocol.file.Handler.openConnection(Unknown Source)

at sun.plugin.AppletViewer.appletInit(Unknown Source)
at sun.plugin.viewer.LifeCycleManager.initAppletPanel(Unknown Source)
at sun.plugin.viewer.IExplorerPluginObject$Initer.run(Unknown Source)

Where the text Thread-6, the number vary's on the number of times I tried to
access the webpage.
ps. Mozilla is giving the exception:
Exception in thread "Thread-2" java.lang.IllegalArgumentException
at sun.net.www.ParseUtil.decode(Unknown Source)

at sun.plugin.AppletViewer.appletInit(Unknown Source)
at sun.plugin.viewer.LifeCycleManager.initAppletPanel(Unknown Source)
at sun.plugin.viewer.WNetscapePluginObject$Initer.run(Unknown Source)

Does anyone know how to solve this problem? Thanks in advantage.

Greetings,

René Beltman.

Given that you are suicidal, I don't think I want to help you solve it.

Did you try running it using the AppletViewer? I just did and it seems
to run fine on my side.

It looks like your classpath has an error. Check if all the directories in
the classpath have valid names and exist.
