iText can be used differently for signing, yes, but first you should tell us what "arxCoSignService.getSignatureOfDataBuffer" really returns. Does it return the naked encrypted digest of the message bytes? Or a PKCS1 data object? Or even a PKCS7 signature container? Or something different still? The answer to that questions determines which additional steps iText must take to actually generate the integrated PDF signature. As a first estimate, unless that arxCoSignService returns a PKCS7 (or CMS) signature container (or you yourself create such a container from the arxCoSignService result), iText will definitively need both externalDigest and certificateChain.
