This code seems to work... the problem is something with the append mode of
FileOutputStream. So use the code below, or the long code I posted earlier
today.
{code:java}
public void saveIncrementalNEW( String fileName ) throws IOException,
COSVisitorException
{
FileInputStream fis = new FileInputStream(fileName);
byte[] ba = IOUtils.toByteArray(fis);
fis.close();
FileOutputStream fos = new FileOutputStream(fileName);
fos.write(ba);
fis = new FileInputStream(fileName);
saveIncremental(fis, fos);
}{code}

Note that even if I fix the (probable) bug, you'll still have the problem I
mentioned several days ago, i.e. you can only pass your file to the external
service in {{sign()}}, not before.

So I was able to reproduce the effect. This code
{code:java}
public void saveIncremental( String fileName ) throws IOException,
COSVisitorException
{
saveIncremental(new BufferedInputStream(new FileInputStream(fileName)),
new BufferedOutputStream(new FileOutputStream(fileName, true)));
}
{code}
is suspicious, because one is writing on the same file than the one where one
is writing, but I'm not sure is the writing start offset is really correct.
Likely the solution would be to read the input into a buffer first and to pass
that one.

{color:#33}indeed. It is still 0.{color}
{color:#33}1) Your file looks as if you called save(). I wonder if
saveIncremental(filename) works at all (your file is also cut off at the end),
our examples use the two parameter method. Make sure that the output file name
is not identical to the input file name.{color}

Tilman Hausherr commented on PDFBOX-4312:

I'm afraid you haven't understood me. You cannot calculate the signature of the
PDF before calling {{sign()}}. The input in {{sign()}} contains the signed PDF
except the signature space. This signed PDF is more than the original PDF, some
data (more than just the signature) is appended to the PDF. So if you are using
an external service to calculate the signature, {{sign()}} must look somewhat
like this:
{code:java}
public byte[] sign(inputStream is)
{
- pack the bytes from is (or a digest, don't know) into XML
- send XML to external service
- wait for response
- check for error
- receive XML response
- extract signature bytes from XML response
- return bytes
}
{code}
If the point of you using an external service is to authenticate once, and then
sign several files in one bug batch, then this isn't possible in 1.8. It is
possible in 2.0.11, see the source code of CreateVisibleSignature in the 2.0.11
source code download and the discussion in PDFBOX-3065.

Your sign() method looks suspicious. The input of this is the data to be
signed. This is NOT identical to the PDF, it is "everything except the
signature area". This data doesn't exist before calling {{saveIncremental}}.
Yet you are passing {{docSigDict["doc"]}} from earlier. Please try to follow
the signature example (see 1.8 source code download) as much as possible.
