Why won't my applet show?
I don't see whats wrong with this code. It looks fine, but the applet on the website doesn't show the gui at all
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;
import javax.swing.*;
publicclass Clientextends JAppletimplements ActionListener
{
publicvoid init()
{
setContentPane(new Client());
}
publicstatic JMenuBar menuBar =new JMenuBar();
publicstatic JMenu file =new JMenu("File");
publicstatic JMenuItem home =new JMenuItem("Main Page");
publicstatic JPanel panel =new JPanel(new BorderLayout());
publicstatic JLabel intro =new JLabel("Welcome.");
public Client(){
setLayout(new BorderLayout());
setJMenuBar(menuBar);
menuBar.add(file);
file.add(home);
home.addActionListener(this);
setLayout(new BoxLayout(panel, BoxLayout.PAGE_AXIS));
panel.add(intro);
}
publicvoid actionPerformed(ActionEvent e){
Object s = e.getSource();
if(s == home){
intro.setText("Once again, welcome!");
}
}
}

What do you see ? Do you see something different if you view the applet using the programme $SDK_home\bin\AppletViewer.exe
Do you get any errors in the JVM plugin console ?
What HTML code are you using to display the applet ?
<!--some browsers require you use an object tag to invoke a JRE plugin-->
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
width="800" height="450" name="ap">
<PARAM NAME="code" VALUE="Client.class">
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.2.2">
<PARAM NAME="scriptable" VALUE="true">
No JDK 1.2 support for APPLET!!
</OBJECT>

Your code was throwing an error at runtime: java.awt.AWTError: BoxLayout can't be shared
It seems like a bug:

Works now:
Hope ive helped.
