JCharts in applets

I'm trying to adapt SwingDemo for working within JApplet, but can't make it 
display anything.
Could you look at my code and tell what is wrong with it?
Thank you!

import org.jCharts.chartData.ChartDataException;
import org.jCharts.chartData.PieChartDataSet;
import org.jCharts.nonAxisChart.PieChart2D;
import org.jCharts.properties.*;

import javax.swing.*;
import java.awt.*;
import java.awt.event.WindowEvent;
import java.awt.image .*;


public class AppletTest extends JApplet
{
	private JPanel panel;
	private PieChart2D pieChart2D;
	private BufferedImage bufferedImage;

	public AppletTest() {
	try {
		initComponents();
	} catch(Exception e) {};
	}

	public void init() {
		this.panel.getGraphics().drawImage(bufferedImage,0,0,this);
	}

	public void start() {
//		this.panel.getGraphics().drawImage(bufferedImage,0,0,this);
	}


	public void initComponents() throws ChartDataException, PropertyException
	{
		this.panel=new JPanel( true );
		this.panel.setSize( 500, 500 );
		this.getContentPane().add( this.panel );

		String[] labels={"BMW", "Audi", "Lexus"};
		String title="Cars that Own";
		Paint[] paints={Color.blue, Color.gray, Color.red};
		double[] data={50d, 30d, 20d};

		PieChart2DProperties pieChart2DProperties=new PieChart2DProperties();
		PieChartDataSet pieChartDataSet=new PieChartDataSet( title, data, labels, 
paints, pieChart2DProperties );

		pieChart2D=new PieChart2D( pieChartDataSet, new LegendProperties(), new 
ChartProperties(), 450, 450 );

		bufferedImage=new BufferedImage( 450, 450, BufferedImage.TYPE_INT_RGB );
		pieChart2D.setGraphics2D( bufferedImage.createGraphics() );
		pieChart2D.render();
	}
}
