I have used iText to fill data into existing AcroForm fields in a PDF.
I am now looking for a solution to add new AcroForm fields to a PDF. Is this possible with iText? If so, how can I do this?

This is documented in the official documentation, more specifically in the SubmitForm example. Additionally, I've written a simple example called AddField. It adds a button field at a specific position defined by new Rectangle(36, 700, 72, 730).
public void manipulatePdf(String src, String dest) throws DocumentException, IOException { PdfReader reader = new PdfReader(src); PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(dest)); PushbuttonField button = new PushbuttonField( stamper.getWriter(), new Rectangle(36, 700, 72, 730), "post"); button.setText("POST"); button.setBackgroundColor(new GrayColor(0.7f)); button.setVisibility(PushbuttonField.VISIBLE_BUT_DOES_NOT_PRINT); PdfFormField submit = button.getField(); submit.setAction(PdfAction.createSubmitForm( "http://itextpdf.com:8180/book/request", null, PdfAction.SUBMIT_HTML_FORMAT | PdfAction.SUBMIT_COORDINATES)); stamper.addAnnotation(submit, 1); stamper.close(); }
As you can see, you need to create a PdfFormField object (using helper classes such as PushbuttonField, TextField,...) and then use PdfStamper's addAnnotation() method to add the field to a specific page.
