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?
