I have a task to rendering a pdf to image using PDF Renderer or iText API, I did it with using PDFRenderer API, But not able to find appropriate solution to zoom in, zoom out, go to next page of rendering pdf image.

Again my issue is when user do search, the matched document will be shown in the Middle portion of the page i.e in document list as

Select file Name file Type
12.pdf pdf
134.pdf pdf
like that and After selecting a document from the grid, the details of PDF from database and thumbnail of the image has to be shown
and separate page should be opened to show entire PDF. This page should not allow right click or saving the page. This page will also contain some zoom in zoom out and navigation control to view the PDF, like go previous page, go to next .

So please give me suggestion.

i have a task to renders password protected pdf file into thumbnails image, I did it with out password protected but unsuccessful when a pdf is password protected.
My old code is

<%@page import="com.sun.pdfview.PDFFile, com.sun.pdfview.PDFPage" %>
<%@page import="java.awt.Image, java.awt.Rectangle" %>
<%@page import="java.awt.Graphics2D, java.awt.image.BufferedImage"%>
<%@page import="java.nio.ByteBuffer, java.nio.channels.FileChannel" %>
<%@page import="*, javax.imageio.ImageIO" %>
<head><title>Image Rendering</title></head>

File file = new File("D:\\Tomcat 5.5\\webapps\\ROOT\\PDF_Test\\R-intro.pdf");
RandomAccessFile raf = new RandomAccessFile(file, "r");
FileChannel channel = raf.getChannel();
ByteBuffer buf =, 0, channel.size());
PDFFile pdffile = new PDFFile(buf);

// draw the first page to an image
PDFPage dpage = pdffile.getPage(0);

//get the width and height for the doc at the default zoom
Rectangle rect = new Rectangle(0,0, (int)dpage.getBBox().getWidth(), (int)dpage.getBBox().getHeight());
BufferedImage bufferedImage = new BufferedImage(rect.width, rect.height, BufferedImage.TYPE_INT_RGB);

//generate the image
Image img = dpage.getImage(
rect.width, rect.height, //width & height
rect, // clip rect
null, // null for the ImageObserver
true, // fill background with white
true // block until drawing is done



Graphics2D bufImageGraphics = bufferedImage.createGraphics();
bufImageGraphics.drawImage(img, 0, 0, null);
ImageIO.write(bufferedImage, "jpg", new File("D:\\Tomcat 5.5\\webapps\\ROOT\\PDF_Test\\Image.jpg" ));

OutputStream strm = response.getOutputStream();


strm.close(); */
<%="Pdf is renders into jpg image which save to location at D:\\Tomcat5.5\\webapps\\ROOT\\PDF_Test\\R-intro.jpg" %>

Congratulation ....its a great score...

Can somebody tell me what will be next? In testing center they gave me only Test report with my result. Will they notice Oracle about exam result? How long it takes Oracle to send me certificate?

As I am from India, I have got my certificate exact at 30th day from my exam date. as my experience within two or three day you will get a mail from regarding to your Sun Microsystems Certification Account Activation, they send you a account authorization code by which you can make an a/c on, from where you can see your certification progress and can download the OCPJP logo.
