I get this message when attempting to run a jFreeChart application. Code:

package chapter04b;

import org.jfree.ChartFactory;
import org.jfree.ChartFrame;
import org.jfree.jFreeChart;
import org.jfree.data.general.DefaultPieDataset;

public class First3 {

/**
* @param args
*/
public static void main(String[] args) {

//create a dataset
DefaultPieDataset dataset = new DefaultPieDataset();
dataset.setValue(“Category 1”, 43.2);
dataset.setValue(“Category 2”, 27.9);
dataset.setValue(“Category 3”, 79.5);

// create a chart
JFreeChart chart = ChartFactory.createPieChart(
“Sample Pie Chart”,
dataset,
true, // legend?
true, // toottips?
false // URLs?
);

// create and display a frame
ChartFrame frame = new ChartFrame(“First”, chart);
frame.pack();
frame.setVisible(true);

}

}

What’s going on???

TIA
