Subject Re: PDFBox 2.0.12 creates invalid PDF/A

Interesting. Using your XML code works here too. So I need to use another XML Tranformer. Actually
it should be Saxon here but I didn't verify this. I'll have a look into this. Thanks.

I just ran CreatePDF.java from the example project with only one line

changed ("id.setPart(2);") and then successfully validated it on

https://www.pdf-online.com/osa/validate.aspx

and with VeraPDF.


The XML is:

I see  one difference in the title line. See this:

Hi,


I'm trying to create PDF/A files using PDFBox 2.0.12. My code is based on the example code
from the PDFBox repo. It creates the PDF file and I can verify XMP data is in it containing
my parameters. But tools like veraPDF and pdfPilot say it's invalid (no PDF/A info, no metadata).


So I converted the file using pdfPilot. I extracted the xpacket XML part from the resulting
PDF file. And I added this data directly without using PDFBox API. And the resulting PDF is
valid to both apps.


So I think the way PDFBox writes XMP data to PDF files, it gets invalid. Can someone confirm
that or is there something wrong in the way I do it?


I also wrote a question on stackoverflow with further infos on this:
