Embedding JAR in html.

[meesterpickles]

I've successfully created a runnable JAR file. Now I'm trying to embed it into html.
I can run it fine by just clicking on the the file, but I'm having trouble running it on my webpage.

Here is the source code if its of any relevance:

package donut;

import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.geom.AffineTransform;
import java.awt.geom.Ellipse2D;

import javax.swing.JPanel;


public class Board extends JPanel{
	
	public void paint(Graphics g)
	{
		super.paint(g);
		Graphics2D g2 = (Graphics2D) g;
		RenderingHints rh = new RenderingHints(RenderingHints.KEY_ANTIALIASING,
											RenderingHints.VALUE_ANTIALIAS_ON);
		
		rh.put(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
		g2.setRenderingHints(rh);
		Dimension size = getSize();
		double w = size.getWidth();
		double h = size.getHeight();
		
		Ellipse2D e = new Ellipse2D.Double(0, 0, 80, 130);
		g2.setStroke(new BasicStroke(1));
		g2.setColor(Color.gray);
		
		for(double deg = 0; deg < 360; deg += 5)
		{
			AffineTransform at = AffineTransform.getTranslateInstance(w/2, h/ 2);
			at.rotate(Math.toRadians(deg));
			g2.draw(at.createTransformedShape(e));
		}
		
	}
	
	public Board()
	{
		
	}

}

package donut;

import javax.swing.JFrame;

public class Donut extends JFrame{

	public Donut()
	{
		add(new Board());
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setSize(360, 310);
		setLocationRelativeTo(null);
		setTitle("Donut");
		setVisible(true);
	}
	
	public static void main(String[] args)
	{
		new Donut();
	}
	
}

Here is what it does:


But when I try to run it on my webpage I get this:


Here are the aforementioned "details" of the previous image:

And finally here is the HTML code I used to embed it:

<APPLET ARCHIVE="donut.jar"
CODE="Donut.class"
WIDTH=360
HEIGHT=310>
</APPLET>

If you require any additional information I will provide it as soon as possible.

Your class Donut is a JFrame, not an Applet. Make it a (J)Applet.

I am now using JApplet instead of JFrame, however I'm having the same error.
Here is my new source:

package donut;

import java.applet.Applet;
import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.geom.AffineTransform;
import java.awt.geom.Ellipse2D;

import javax.swing.JApplet;
import javax.swing.JPanel;


public class Board extends JApplet{
	
	public void init()
	{
		add(new Board());
		setSize(360, 360);
		setVisible(true);
	}
	
	public void paint(Graphics g)
	{
		super.paint(g);
		Graphics2D g2 = (Graphics2D) g;
		RenderingHints rh = new RenderingHints(RenderingHints.KEY_ANTIALIASING,
											RenderingHints.VALUE_ANTIALIAS_ON);
		
		rh.put(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
		g2.setRenderingHints(rh);
		Dimension size = getSize();
		double w = size.getWidth();
		double h = size.getHeight();
		
		Ellipse2D e = new Ellipse2D.Double(0, 0, 80, 130);
		g2.setStroke(new BasicStroke(1));
		g2.setColor(Color.gray);
		
		for(double deg = 0; deg < 360; deg += 5)
		{
			AffineTransform at = AffineTransform.getTranslateInstance(w/2, h/ 2);
			at.rotate(Math.toRadians(deg));[QUOTE][/QUOTE]
			g2.draw(at.createTransformedShape(e));
		}
		
	}
	
	public static void main(String args)
	{
		
	}

}

Also, here is my manifest file:

Manifest-Version: 1.0
Created-By: 1.6.0 (Sun Microsystems Inc.)
Main-Class: donut.Board

[Tolls]

Assuming your applet tag is the same I'm not surprised...your applet is donut.Board, not Donut.

[DarrylBurke]

A jar for an Applet doesn't require a Main-Class. The class to be run is read from the HTML tag.
