You mean a way to make a hybrid applet/application, that can run as
either?  The simplest way is of course to use appletviewer, but I'm
guessing that's not what you want.

If you want a hybrid applet/application, you will need to add some code
that does what the browser does.  Here is a main method that should get
you started:

public static void main (String args[]) {
    // set applet flag
    // your class should define this variable as a static
    inApplet = false;

    // Create the frame to hold the applet. This can be a
    // Frame or JFrame
    JFrame frame = new JFrame ("Applet Frame");

    // instantiate the applet
    MyApplet applet = new MyApplet();

    // add the applet to the frame
    frame.getContentPane().add (applet, BorderLayout.CENTER);

    // resize the frame and make it visible
    frame.setSize (640, 480);
    frame.setVisible (true);

    // run the methods the browser normally would
    applet.init();
    applet.start();
}

Depending on what your applet does, this might be all you need to do.
If, however, your applet calls getAppletContext(), getParameter(),
getCodeBase(), or getDocumentBase(), then you will need to override
these methods to do something sensible.  That's where the inApplet flag
comes into play: if inApplet is true, you just call the super and you're
done.  There may also be other methods, but I think those are the most
important ones.

HTH,
Jason
