JFREE error

hi.........

the code for making chart is: WHICH IS GIVING THE ERROR

import org.jfree.chart.*;
import org.jfree.data.category.*;
import org.jfree.data.general.DefaultPieDataset;
import org.jfree.data.xy.*;
import org.jfree.data.*;
import org.jfree.chart.renderer.category.*;
import org.jfree.chart.plot.*;
import java.awt.*;

public class BarExample1{
public static void main(String arg[]){
  DefaultCategoryDataset dataset = new DefaultCategoryDataset();
  dataset.setValue(2, "Marks", "Rahul");
  dataset.setValue(7, "Marks", "Vinod");
  dataset.setValue(4, "Marks", "Deepak");
  dataset.setValue(9, "Marks", "Prashant");
  dataset.setValue(6, "Marks", "Chandan");
  JFreeChart chart = ChartFactory.createBarChart
  ("BarChart using JFreeChart","Student", "Marks", dataset, 
   PlotOrientation.VERTICAL, false,true, false);
  chart.setBackgroundPaint(Color.yellow);
  chart.getTitle().setPaint(Color.blue); 
  CategoryPlot p = chart.getCategoryPlot(); 
  p.setRangeGridlinePaint(Color.red); 
  ChartFrame frame1=new ChartFrame("Bar Chart",chart);
  frame1.setVisible(true);
  frame1.setSize(400,350);
  }
}

IN THIS WE DONT REQUIRE THE RECTANGLEINSETS NA THEN WHY ITS GIVING ME THE ERROR.
