You're right, the same validation error occurs in 2.0.29 for that PDF. It seems to me that the generation of the PDF differs from v2 to v3 (?). I tried just creating a simple page for each, and only PDFBox 3 gives me the ", /XRef cross reference streams are not allowed". See code snippets below.
PDFBox 2: https://gist.github.com/enstulen/5aad78b7a590a50bced25f54591a90ea PDFBox 3: https://gist.github.com/enstulen/74b504a35db524bd6a0493fd6f82a926 I also attached two PDFs generated with our code with PDFBox 2 and 3. If it helps: the code for our PDF generation is here <https://github.com/navikt/innsending-api/blob/main/innsender/src/main/kotlin/no/nav/soknad/pdfutilities/PdfGeneratorTools.k>, and the PR to upgrade to v3 is here <https://streaklinks.com/BrNsiiaaWnLs7YdkGQV0GJoM/https%3A%2F%2Fgithub.com%2Fnavikt%2Finnsending-api%2Fpull%2F103%2Ffiles> (there aren't really any changes to the PDF generation itself). I tested with an online PDF validator <https://streaklinks.com/BrNsiieHR46g-CiyZw229TCo/https%3A%2F%2Fwww.pdf-online.com%2Fosa%2Fvalidate.aspx> and only the v3 PDF has the XRef validation error. If the PDFBox 3 validation is correct, what is required to fix the validation for XRef? ᐧ On Sat, Sep 23, 2023 at 5:22 AM Tilman Hausherr <thaush...@t-online.de> wrote: > I get the same "error" with 2.0.29. > > Tilman > > > On 20.09.2023 17:00, Morten Stulen wrote: > > After upgrading to PDFBox 3, the PreflightParser.validate() function > > returns an error. > > "Trailer Syntax error, /XRef cross reference streams are not allowed" > > > > Code: > > > > fun isValid(bytes: ByteArray): Boolean { > > val fileName = "tmp_${UUID.randomUUID()}.pdf" > > val file = File(fileName) > > > > val document = Loader.loadPDF(bytes) > > document.save(fileName) > > > > // This returns a ValidationError > > val result = PreflightParser.validate(file) > > > > return result.isValid > > } > > > > The tested PDFs are the same as before the upgrade. > > > > > > > > ᐧ > > > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@pdfbox.apache.org > For additional commands, e-mail: users-h...@pdfbox.apache.org > >
