also i want to know how to get the image after put it in the database.
please help me, it's so urgent.

Answer 1

This is a way of getting the image out of the database.
class yourClass{
private byte[] buff;
private ByteArrayOutputStream byteArrayOutputStream;
public yourClass()
Statement statement = connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
ResultSet result = statement.executeQuery("your query");
while ( result.next()){
try{
BufferedInputStream bin = new BufferedInputStream(rs.getBinaryStream("imagecolumn"));
byteArrayOutputStream = new ByteArrayOutputStream();
int length = bin.available();
buff = new byte[length];
while ( bin.read( buff, 0, length ) != -1 ) {
byteArrayOutputStream.write( buff, 0, length );
bin.close();
catch(Exception e){
The class about is used to take the image out of the database and store it in an object which is then streamed out through a servlet to display on the jsp page.
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.sql.*;
public class ImageServlet extends HttpServlet {
public void init() throws ServletException {    }
public void destroy() {    }
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
try
yourClass pro = (yourClass)request.getSession().getAttribute("object");
while ( iterator.hasNext() ) {
pro = ( Product ) iterator.next();
response.setContentType("image/jpg");
ByteArrayOutputStream byteArrayOutputStream = pro.getImage();
response.setContentLength( byteArrayOutputStream.size() );
response.getOutputStream().write( byteArrayOutputStream.toByteArray() );
response.getOutputStream().flush();
return;
catch (Exception e)
e.printStackTrace();
throw new ServletException(e);
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
This is a little messy but if you search the forums you will find out more on it. Search for Images and database.
