Hi.
I tryed another thing, created a blank signature field, now i can see it,
but it disapears when signing.
My hair is dying white, this is terrible.
import java.io.*;
import java.util.*;
import java.security.*;
import java.security.cert.*;
import com.lowagie.text.*;
import com.lowagie.text.pdf.*;
public class LittleTest {
public static void main(String args[]) throws Exception {
PdfReader reader1 = new PdfReader("testv15.pdf");
PdfStamper stamper = new PdfStamper(reader1, new
FileOutputStream("testv15_2.pdf"));
AcroFields form = stamper.getAcroFields();
form.setField("text1", "Value has been changed !!!");
//stamper.setFormFlattening(true);
//Now Let's Try To Add A Signature Field
PdfFormField sig = PdfFormField.createSignature(stamper.getWriter());
sig.setWidget(new Rectangle(100, 100, 200, 200), null);
sig.setFlags(PdfAnnotation.FLAGS_PRINT);
sig.put(PdfName.DA, new PdfString("/Helv 0 Tf 0 g"));
sig.setFieldName("Signature1");
sig.setPage(1);
stamper.addAnnotation(sig, 1);
stamper.close();
KeyStore ks = KeyStore.getInstance("pkcs12");
ks.load(new FileInputStream("ksb_cred.pfx"), "fujiwara".toCharArray());
String alias = (String)ks.aliases().nextElement();
PrivateKey key = (PrivateKey)ks.getKey(alias, "fujiwara".toCharArray());
java.security.cert.Certificate[] chain = ks.getCertificateChain(alias);
reader1 = new PdfReader("testv15_2.pdf");
FileOutputStream fout = new FileOutputStream("testv15_2_signed.pdf");
PdfStamper stp = PdfStamper.createSignature(reader1, fout, '\0');
PdfSignatureAppearance sap = stp.getSignatureAppearance();
sap.setCrypto(key, chain, null, PdfSignatureAppearance.WINCER_SIGNED);
sap.setReason("For no reason at all");
sap.setLocation("V. Castelo");
// comment next line to have an invisible signature
sap.setVisibleSignature("Signature1");
stp.close();
}
}
