Hi!
Thank you all for your help! :)
I've installed Foxit PDF Reader and this tool shows the signature!
It's hard to believe but this strange signature-behaviour indicates a
bug in Acrobat?!
The signature is there but Acrobat tools do not show it :(

This is really strange. The signature is in the PDF but after reading it
with Acrobat the signature disappears from the doc, no trace of it. I'll
need to think a bit more about this.

Thank you very much! :-)
Attached you find four pdf-Files:
Empty page, signed empty page, page with one form and this
one signed...

It would help to post the original pdf, the pdf with the form and the
signed pdf.

Hello all.
I've written a java-method signing pdf-documents (which are created
by the tool scribus) using itext. With standard pdf documents
no problems... But if the scribus pdf contains only one form,
something went wrong. The resulting signed pdf doesn't show the
signature although it is in the "pdf-code" (Opened with
word-pad ;-) )
Even using the setFormFlattening(true) does not help...
Surprisingly the PDF-Analyzer 2.5 preview-mode shows the digital
signature but all other tools don't.
Here's the code:
public static void signDocument(String zertifikat, String
passphrase, String
inputFile, String outputFile, String reason, String location) {
try {
KeyStore ks = KeyStore.getInstance("pkcs12");
ks.load(new FileInputStream(zertifikat),
passphrase.toCharArray());
String alias = (String)ks.aliases().nextElement();
PrivateKey key = (PrivateKey)ks.getKey(alias,
passphrase.toCharArray());
Certificate[] chain = ks.getCertificateChain(alias);
PdfReader reader = new PdfReader(inputFile);
FileOutputStream fout = new FileOutputStream(outputFile);
PdfStamper stp =
PdfStamper.createSignature(reader, fout, '');
PdfSignatureAppearance sap =
stp.getSignatureAppearance();
sap.setCrypto(key, chain, null,
PdfSignatureAppearance.WINCER_SIGNED);
sap.setReason(reason);
sap.setLocation(location);
sap.setVisibleSignature(new
Rectangle(450,700,550,800), 1, null);
stp.close();
} catch (Exception e) {
System.out.println(e);
}
}
Scribus -> new empty page -> pdf -> signing -> signed pdf works fine
Scribus -> new empty page -> Insert form -> pdf -> signing ->
signed pdf does
not work,
same configurations...
Any ideas?
Thank you very much!
