Fail to load document (Solved)

Hi ,
this problem is solved using the code below:

response.reset();
response.setHeader("Expires", "0") response.setHeader("Cache
-Control", "must-revalidate, post-check=0, pre-check=0");
response.setHeader("Pragma", "no-cache");
response.setHeader("Content-disposition", "attachment; filename=\""
+ issueDate + ".pdf\"");

response.setContentType("application/pdf");

Document document = new Document(PageSize.A4);

OutputStream out = response.getOutputStream();
PdfWriter.getInstance(document, out);

document.open();

/*8
* data holds blob retrieved
*/

byte data[] = null;

data = imageData
Image image2 = Image.getInstance(data);
document.add(image2);
document.newPage();
}

document.close();
But this time I have a new problem.

once I open the document every thing is as expected. When I go down the pages
and return back. Every thing is erased.

If I reopen this document the same thing is happenning.
Can any one please tell me if it is my Documents problem.
I am usin Evince Document Viewer that comes with linux.

I am repeatedly getting this error when I open a pdf file created by my server.

UNABLE TO OPEN DOCUMENT
Fail to load document (error:3) 'file;///location/myfile.pdf'

My code to generate this file is this:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Document document = new Document(PageSize.A4);

PdfWriter.getInstance(document, baos);
document.open();
document.add(new Paragraph(new Date().toString()));
for(int j=0; j<100;j++){
document.add(new Paragraph("sagri your pdf is working well"));
document.add(Chunk.NEWLINE);
}
response.setHeader("Expires", "0");
response.setHeader("Cache-Control", "must-revalidate, post-check=0,
pre-check=0");
response.setHeader("Pragma", "public");
response.setHeader("Contgent-disposition", "attachment; filename=\""
+ issueDate + ".pdf\"");
response.setContentType("application/pdf");
response.setContentLength(baos.size());
ServletOutputStream out = response.getOutputStream();
baos.writeTo(out);
out.flush();

document.close();
*************************************************************************
Instead of printing a line i wanted to add a image using

[[[[ byte[] imagedata = null;
try {
Blob image = page.getFile();
imagedata = image.getBytes(1, (int) image.length());
} catch (Exception e) {
log.error("Exception in getting the file", e);
return null;
}
return imagedata;
]]]]

byte[] data = imagedata;
Image image2 = Image.getInstance(200, 150, 3, 8, data);
document.add(image2);

when I execute this code the generated exception shows unknown source for
image2.

Exception:....................document.add(unknown source)..........

what way can we add data to a pdf that can be downloadable .
