Generating pdf from jtable

[Mamatha Rudrappa]

I am developing a tool in java to generate pdf from jtable.
I tried to use itext but I am getting black pdf. Below is the code that I used.

import java.awt.BorderLayout;
import java.awt.Graphics2D;
import java.awt.Shape;
import java.io.FileOutputStream;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTable;

//import com.itextpdf.awt.PdfGraphics2D;
import com.itextpdf.text.Document;
import com.itextpdf.text.PageSize;
import com.itextpdf.text.pdf.PdfContentByte;
//import com.itextpdf.text.pdf.PdfTemplate;
import com.itextpdf.text.pdf.PdfWriter;

public class Pdf extends JFrame {
  /**
     *
     */
    private static final long serialVersionUID = 1L;
private JTable table;

  public Pdf() {
    getContentPane().setLayout(new BorderLayout());
    createTable();
  }
  private void createTable() {
    Object[][] data = {{ "a", "b", "e", new Integer(5), new Boolean(false) } };
    String[] columnNames = { "A", "B", "C", "D", "E" };

    table = new JTable(data, columnNames);

    JPanel tPanel = new JPanel(new BorderLayout());
    tPanel.add(table.getTableHeader(), BorderLayout.NORTH);
    tPanel.add(table, BorderLayout.CENTER);

    getContentPane().add(tPanel, BorderLayout.CENTER);
  }
  private void print() {
    Document document = new Document(PageSize.A4.rotate());
    try {
      PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("jTable.pdf"));

      document.open();
      PdfContentByte cb = writer.getDirectContent();

      cb.saveState();
      Graphics2D g2 = cb.createGraphicsShapes(500, 500);

      Shape oldClip = g2.getClip();
      g2.clipRect(0, 0, 500, 500);

      table.print(g2);
      g2.setClip(oldClip);

      g2.dispose();
      cb.restoreState();
    } catch (Exception e) {
      System.err.println(e.getMessage());
    }
    document.close();
  }
 
  public static void main(String[] args) {
    Pdf frame = new Pdf();
    frame.pack();
    frame.setVisible(true);
    frame.print();
  }
 
}

Can anyone help me please..................?

Also to purchase 3rd party api's or libraries, which ones are good?

Thank you..

It looks like you took the code from http://www.java2s.com/Tutorial/Java/0419__PDF/CreatePdfdocumentfromJTable.htm and modified it. Does the original example on java2s.com work for you?

Thank you for the reply.
No, example from java2s.com does not work. It generates a blank pdf.
I am not sure what wrong i am doing..
