Adam - I'm confused!! You are directly writing XFA form information (via fillXfaForm) _BUT_ then you use the acroFields APIs to change the lock state - you can NOT mix these two! Either you are working with XFA _OR_ you are working with AcroForms. It's like cross the streams....

In case it's useful to anyone else, here's the core code I've ended up with to fill in and lock an XFA form (ignoring any AcroForm parts). This code doesn't include any exception handling, checks, or other PDF manipulation, it's just to show the form filling & securing part... InputSource is = new InputSource(new StringReader(passedXfaData)); is.setEncoding("UTF-8"); ByteArrayOutputStream baos = new ByteArrayOutputStream(); PdfStamper stamper = new PdfStamper(passedPdfReader, baos); // must have ALLOW_FILL_IN otherwise fillXfaForm() silently fails stamper.getWriter().setEncryption(PdfWriter.ENCRYPTION_AES_128, "", "", PdfWriter.ALLOW_PRINTING | PdfWriter.ALLOW_FILL_IN); // mergeXfaData() ignores an XFA form if there is also an AcroForm in the PDF // So get the XfaForm explicitly and fill that, so no AcroForm stuff happens. AcroFields acroFields = stamper.getAcroFields(); XfaForm xfaForm = acroFields.getXfa(); xfaForm.fillXfaForm(is); // once the form is filled in, we have to mark each of the fields as readonly // so the users can't edit the values in the final PDF. HashMap<String, AcroFields.Item> fieldMap = acroFields.getFields(); for (String fieldName : fieldMap.keySet()) { acroFields.setFieldProperty(fieldName, "setfflags", PdfFormField.FF_READ_ONLY, null); } stamper.setFullCompression(); stamper.close(); return baos.toByteArray(); Thanks again to Mark and Leonard for all the help, it's much appreciated.
