PDFBox-generated PDF/A-1b not validated using PDFBox validation

[Julien Béti <ju...@beti.name>]

Hello,

Attached, you'll find a sample java code which creates a PDF/A-1b file  
using CreatePDFA sample [1], and then immediately tries to validate it  
using Preflight as described in Cookbook [2]

The validation fails with the following error:
--8<----------------
The file/tmp/test.pdf is not valid, error(s) :
7.1 : Error on MetaData, xmp should start with a processing instruction
-->8----------------

I'm using PDFBox to generates PDF/A files which are validated by an  
application which obviously uses PDFBox for validation, and my PDF  
files are rejected for the moment, with the same error.

Could you please tell me what's missing in CreatePDFA sample to make  
it pass the validation?

Kind Regards,

Julien.

I can confirm this solves the issue in my project too.
Thanks!

I didn't test the file from your code, only the one from the example, 
both with preflight and with
http://www.pdf-tools.com/pdf/validate-pdfa-online.aspx

If you want to be really sure, when you continue with development, check 
your files with the 2.0 version of the preflight app command line:

https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/preflight-app/2.0.0-SNAPSHOT/

because some of the improvements in preflight haven't been made to 1.8.

change "false" to "true", it should work then.
