You mean Code sample 5.2: "Checking the integrity of a revision based on a digital signature" in section 5.1.2 "Checking the integrity of a revision" of the white paper http://itextpdf.com/book/digitalsignatures? That code merely checks whether the signature can be parsed and the hash value is correct. Or do you mean Code sample 5.5: "Verifying certificates" in section 5.3.2 "Verifying a signature against a key store" in the same paper? That code only checks whether a certificate chain rooted in a trusted certificate can be built. Or Code Sample 5.6: "Checking if a certificate was valid on a specific day"? No online check either. Or Code Sample 5.8: "Checking the validity of a certificate using OCSP"? In this case, an online check is executed. If it falsely returns "valid", please supply a sample document.
