PDF Form filling with java and iText
I've been looking at PDF form filling with Java so I can use it with Railo and I came across iText, a Free Java-PDF Library.
I couldn't find a simple explanation of populating a PDF form in java so my below example assumes you have a PDF called "SimpleRegistrationForm.pdf" and it has 4 fields in it: name, address, postal_code, and email The completed form will be saved to a file called filledOutForm.pdf

24 public static void main(String[] args) throws IOException, DocumentException {

26 PdfReader reader = new PdfReader(
27 "/dir/to/pdf/SimpleRegistrationForm.pdf");
28 PdfStamper filledOutForm = new PdfStamper(reader, new FileOutputStream(
29 "/dir/to/pdf/filledOutForm.pdf"));

31 AcroFields form = filledOutForm.getAcroFields();
32 form.setField("name", "Andy Jarrett");
33 form.setField("address", "1 infinite road");
34 form.setField("postal_code", "1SW");
35 form.setField("email", "mail@example.com");
36
37 filledOutForm.close();
