I have updated the version of iText we are using to 5.0.5 and made the required
package changes. When the PDF is being stamped within our application, we get
the following error:
500 Servlet Exception
java.lang.NullPointerException
at com.itextpdf.text.pdf.PdfPKCS7.<init>(PdfPKCS7.java:577)
at com.itextpdf.text.pdf.PdfSigGenericPKCS.setSignInfo(
PdfSigGenericPKCS.java:95)
at com.itextpdf.text.pdf.PdfSignatureAppearance.preClose(
PdfSignatureAppearance.java:973)
at com.itextpdf.text.pdf.PdfSignatureAppearance.preClose(
PdfSignatureAppearance.java:897)
at com.itextpdf.text.pdf.PdfStamper.close(PdfStamper.java:192)
I took a look at 5.0.5's source code for PdfPKCS7.java leading me to this line
of code:
signCert = (X509Certificate)certChain[0];
Is there a configuration issue with the PDFStamper or PdfSignatureAppearance,
or is this problem related to the actual certificate being used to sign the
PDF?
Thanks again. Your help is appreciated.
Regards,
Adam
