Can't sign

Aspose.PDF Product Family
1

Hi,

We are having a nullpointerexception at save method. We convert a docx to PDF and then we try to sign the pdf file. Converting docx to PDF is ok but we have troubles at signing.

We use this code to do that:

documento.save("/home/tmp/aspose.pdf");

Signature sgn = new Signature();
sgn.setLocation(“Lima”);
sgn.setName(“Omar”);
sgn.setReason(“Alguna razon”);
sgn.setRect(new java.awt.Rectangle(200, 500, 150, 150));
try {
PdfFileSignature pdfSign = new PdfFileSignature();
InputStream fileStream = new FileInputStream("/home/tmp/aspose.pdf");
pdfSign.bindPdf(fileStream);
pdfSign.setCertificateFile("/home/tempo/analista.pfx");
pdfSign.setSignModel(PdfFileSignature.SELF);
pdfSign.setPageNumber(1);
pdfSign.setPassword(“12345”);
pdfSign.setSignature(sgn);
pdfSign.save("/home/tmp/asposesigned.pdf");
} catch (Exception e) {
log.error(e.getMessage(), e);
throw new RuntimeException(“NO SE PUEDE FIRMAR”);
}

NullPointerException occurs in the line “pdfSign.save(”/home/tmp/asposesigned.pdf");"

asposesigned.pdf is created but corrupted or damaged and we can’t open it.

Thanks for your help
