Configuration :: Java Applet - IIS Web Server Public Folder Doesn't Work Anymore

I am trying to write an asp.net webpage which contains an applet. Everything works fine when I run this in a development folder, but when I move it to the IIS web server public folder it doesn't work anymore. I don't get any error message. The browser doesn't repaint the applet area Here is the source code:

//web page
<script src="http://www.java.com/js/deployJava.js"></script>
<script>
var attributes = { code:'ImageApplet.class', archive:'ImageApplet.jar', width:864, height:1000} ;
var parameters = {jnlp_href: 'image-applet.jnlp'} ;
deployJava.runApplet(attributes, parameters, '1.4');
</script>
//applet
public void init() {
buildUI();
}
public void buildUI() {
JButton jumbleButton = new JButton("Jumble");
jumbleButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
};
});
add("South", jumbleButton); }
