See http://mindprod.com/products.html#DOWNLOAD for the source code.

You can't use it in an Applet unless the Applet is signed. Applets are
not allowed to read or write the hard disk.

Yep. I posted a solution to a thread
titled 'applet showDocument work with file protocol'
on the 14th, but strangely it is not showing
at Google, so here it is again..

<sscce>
import java.applet.Applet;
import java.awt.*;
import java.net.*;

/** Can a Java Applet use 'showDocument' for
files? This small example demonstrates you can.

@version 2004-04-15 */
public class FileFromServerApplet extends Applet {
public void init() {

TextArea ta = new TextArea();
add( ta );
validate();

URL url;
try {
url = new URL( getCodeBase().
toExternalForm() + "FileFromServerApplet.java");
getAppletContext().showDocument( url, "_blank" );
ta.setText( "File displayed" );
} catch (Exception e) {
ta.setText( e.toString() );
}
}
}
</sscce>

Of course, if you user complains,
'but that shows in the browser window'
tell them 'it's your own damn browser -
configure it how you want it' ..then
stride off, whistling loudly. ;-)
