Java: Show image in a table of PDF from database

The following program will show you how to show image in  the table of a pdf  using java and iText. It is too much easy.  If you face any problem to understand please leave a reply.

** I have used NetBeans IDE 5.0  and JDK 1.4.2 –Old Version 😦

 ** To run this Code, you have to add pgsql.jar (postgre sql driver),iText-2.1.7.jar( To Create PDF) in your classpath

The OutPut will be like this:

/*****************************************************/

package db2pdf;

import java.io.*;

import com.lowagie.text.*;

import com.lowagie.text.pdf.*;

import java.sql.*;

import java.util.*;

import java.io.*;
