Hello,
I've made a simple jar to protect and sign PDFs where the signing part is
copied from this example:
http://itextpdf.sourceforge.net/howtosign.html#howtosign.
It works great from the command-line (Debian), but fails on the line
"ks.load(new FileInputStream("/path/to/cert/certificate.p12"),
"password".toCharArray());" when I try to execute the Jar using the PHP exec
function (exec("java -jar /path/to/jar/SignPDF.jar /path/to/pdf/original.pdf
/path/to/pdf/signed.pdf", $response);), although it doesn't return any error
message.
I've tried to chown to www-data and chmod to 777 the Jar and the certificate
files, but it didn't help.
Any suggestions about what might be wrong?
Please bear in mind that I'm quite unexperienced with both Java and iText.
Thank you,
Pedro

Certificate[] chain = ks.getCertificateChain(alias);

PdfStamper stp = PdfStamper.createSignature(reader, fout, '\0');
PdfSignatureAppearance sap = stp.getSignatureAppearance();
sap.setCrypto(key, chain, null, PdfSignatureAppearance.WINCER_SIGNED);
sap.setVisibleSignature(new Rectangle(250, 130, 500, 190), 1, "Campo de firma");
sap.setCertificationLevel(PdfSignatureAppearance.CERTIFIED_NO_CHANGES_ALLOWED);
stp.close();------------------------------------------------------------------------------
