I have no clue how to import FDF document into PDF using PDFBox. Here is
what I tried, it just opens the pdf form with no data filled in.
String targetDirectory=System.getProperty("java.io.tmpdir");
File fout = new File(targetDirectory+"/newfile.fdf");
FileOutputStream fos = new FileOutputStream(fout);
BufferedWriter bw = new BufferedWriter(new
OutputStreamWriter(fos));
bw.write("%FDF-1.2");
bw.write("1 0 obj <<");
bw.write("/FDF <<");
bw.write("/F(https://servername/abc.pdf)");
bw.write("/Fields[");
bw.write("<</T(FieldName)/V (Sample Value)>>");
bw.write("]");
bw.write(">>/Type/Catalog");
bw.write(">>");
bw.write("endobj");
bw.write("trailer");
bw.write("<</Root 1 0 R>>");
bw.write("%%EOF");
bw.close();
FDFDocument fdfdoc=new FDFDocument();
fdfdoc.load(new File(targetDirectory+"/newfile.fdf"));
System.out.println("a:"+fdfdoc.getDocument().getCOSObject().toString());
pdfDoc = PDDocument.load("https://servername/abcTemp.pdf";);
PDDocumentCatalog docCatalog = pdfDoc.getDocumentCatalog();
PDAcroForm acroForm = docCatalog.getAcroForm();
//acroForm.setXFA(null);
acroForm.importFDF(fdfdoc);
FacesContext facesContext = FacesContext.getCurrentInstance();
HttpServletResponse response = JSFUtil.getServletRespone();
response.setContentType("application/pdf");
response.addHeader("Content-Type",
"application/force-download");
response.addHeader("Content-Disposition", "attachment;
filename=\"abc.pdf\"");
ServletOutputStream outStream = response.getOutputStream();
pdfDoc.save(outStream);
facesContext.responseComplete();
