I am sorry if I am unable to express my querry.
I am giving the whole code that I am using for this document
public ActionForward downloadPDF(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
String issueDate = request.getParameter("issueDate");
CareerLetterIssue careerLetterIssue = careerLetterIssueManager
.getCareerLetter(issueDate);
/**
* collection of pages contained in this letter
*/
List pages = careerLetterIssue.getPages();
Document document = new Document(PageSize.A4);
OutputStream out = response.getOutputStream();
PrintWriter pdf = response.getWriter();
document.open();
response.reset();
response.setContentType("application/pdf");
// setting the content type
response.setHeader("Content-disposition", "attachment; filename=\""
+ issueDate + ".pdf\"");
response.setHeader("Cache-Control",
"must-revalidate, post-check=0, pre-check=0");
response.setHeader("Pragma", "no-cache");
response.setHeader("Expires", "0");
/*8
* data holds blob retrieved as byte array
*/
byte data[] = null;
for (int i = 0; i < pages.size(); i++) {
CareerLetter cl = (CareerLetter) pages.get(i);
String pageNumStr = cl.getPageNum();
data = ""> issueDate);
Image pdfImage = Image.getInstance(data);
document.add(pdfImage);
if (i < pages.size() - 1) {
document.newPage();
}
}
pdf.flush();
document.close();
response.flushBuffer();
out.close();
return null;
}
The program is running fine.
I am able to download this pdf and save it.
I am using Evence Document Viewer
I am able to view them for a single time.
When I am at(say) page no. 5, all the images from page no. 3 to page no. 1 are dis-appearing.
Can you please suggest me some other way of writing images to my pdf.
Please help..

I assume you realize that this isn't an iText related problem.
iText creates the PDF correctly; otherwise the images would
have been blank to start with. The problem is browser/plug-in related.

If a problem isn't iText related, changing the code won't help.
Except maybe if you add the images 'inline' instead of as
'Image XObjects', but I can't guarantee this will give you
a better result.

You should disable the back button, or, as I suggested a few
days ago in answer to another question, serve the PDF as
'attachment' instead of 'inline'. When you serve the PDF as
attachment, the PDF isn't shown in the Adobe Reader browser
plug-in, but in a separate Adobe Reader window (not a browser
window). The keywords to search for are: "Content-Disposition"
and "attachment" (versus "inline")
best regards,
Bruno
