Thanks, Tilman!
I tried that and made some progress, but when I view the file in the PDF
Debugger the Metadata object is still null, although the "Length" property
now shows the right size of the string I applied... Weird, no?
Here's the code I added:
OutputStream outStream = s.createOutputStream();
String jsonString = "<x:xmpmeta xmlns:x=\"adobe:ns:meta/\" x:xmptk=\"Adobe
XMP Core 5.4-c006 80.159825, 2016/09/16-03:31:08\"></x:xmpmeta>";
outStream.write(jsonString.getBytes());
outStream.close();
Do you see any issues with it?
It looks ok... here's the code from the PDMetadata class:
public void importXMPMetadata( byte[] xmp )
throws IOException
{
try (OutputStream os = createOutputStream())
{
os.write(xmp);
}
}
}
Maybe create a minimal fully (almost) working program (remove all that
isn't relevant) and share your code.

Hi all,
I have a signed document where the Signature field's value contains a
Metadata dictionary with some info in it. I'm trying to reproduce this
using PDFBox but am having a hard time doing so.
This is what the original structure of the file looks like:

I've used CreateVisibleSignature as my base, and manipulated its
findExistingSignature method to create the Metadata dictionary and add it
to the field's value, but I don't manage to set the actual contents of
the
object (seen in the right-hand side of the screenshot above). This is the
code I added:

call COSStream.createOutputStream() and then write there and close it.

The result is nearly identical to the original, just without any actual
value under the Metadata object:

It seems like I'm missing something quite basic here, so any advice would
be appreciated!
