Subject: [iText-questions] Adding javascript to existing pdf to print


Hey Guys,

I understand that this question has been asked before, but something is not
working for me. I have a PDF doc (as a byte array). I want to add javascript
to it, so that it prints out on the client. Pasted below is my code

When I do a document.close(), I get an error "The document has no pages". I
am not sure, what I am doing wrong.
I tried to add some content to the doc, but then, it only prints the new
content.
I also tried to add javascript to the document object, instead of the
writer, but that doesn't work either.

Can someone help me with this.  Thank you so much guys*

byte[] pdfData = dctxt.getDocData();  // getting the pdf data
ByteArrayOutputStream bos = new ByteArrayOutputStream(pdfData.length);
bos.write(pdfData);
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, bos);
writer.setViewerPreferences( PdfWriter.HideMenubar | PdfWriter.HideToolbar|
PdfWriter.HideWindowUI );
document.open();
writer.addJavaScript(
  "this.print({bUI: false,bSilent: false,bShrinkToFit: true});" +
  "\r\n" +
  "this.closeDoc();"
  );
document.close();
response.setHeader("Content-Type", "application/pdf");
response.setContentLength(bos.size());
OutputStream os = response.getOutputStream();
bos.writeTo(os);
os.flush();
os.close();
