You're throwing a Rather Large chunk of code at us and then expecting us
to execute it (on our own servlet-capable server) to get the resulting
PDF. That's fine for commercial support, but that's not what this
mailing list is for.
I suggest you remove the PDF code from your servlet code. Get it
working "stand alone" with basic file I/O first, then wrap it in a
servlet.
Having said that, nothing in your code is jumping out at me as The
Problem:
//This would simulate the pdf we would display to customer to fill out
InputStream is =
getServletContext().getResourceAsStream("wwwroot/sample2.pdf");
// We create a reader with the InputStream
PdfReader reader = new PdfReader(is, null);
// We create an OutputStream for the new PDF
ByteArrayOutputStream baos = new ByteArrayOutputStream();
// Now we create the PDF
PdfStamper stamper = new PdfStamper(reader, baos);
// We get submit button from existing form and change the submit
properties of which
AcroFields form = stamper.getAcroFields();
PushbuttonField button =
form.getNewPushbuttonFromField("ScalepointButton");
PdfFormField submit = button.getField();
submit.setAction(PdfAction.createSubmitForm("http://localhost:8084/PDFFo
rms/CapturePdf?category=" + category, null, PdfAction.SUBMIT_PDF));
form.replacePushbuttonField("ScalepointButton", submit);
stamper.close();
// We write the PDF bytes to the OutputStream
OutputStream os = response.getOutputStream();
baos.writeTo(os);
os.flush();

Subject: [iText-questions] How to update A PushbuttonField on an
existing PDF
Hi iText,
First of we are very much interested in using this application
to our product.
Currently we are new to this and still testing this if it could
cater our needs.
What I'm trying to do is to get an existing PDF as stream, then
setting the url of a pushbutton field that is already existing in the
PDF, then showing that PDF with the modified action.
The PDF is displayed but there was no change in the button.
Could you please point me on the right direction on this.
I have attached here the PDF file and the Servlet that supposed
to display the pdf with the modified button.
Your help would be greatly appreciated.
Thanks,
Nelson
