Create a facturX with Mustang from XML String

I'm trying to build a facturx using Mustang library in an API. I have a (valid) XML string as entry

@PostMapping
public FxResponse createFacturX(@RequestBody XmlRequest request) throws IOException {
    if(request.getVersion() == null) {
        request.setVersion(2);
    }

    ByteArrayOutputStream output = new ByteArrayOutputStream();
    log.debug("Converting to PDF/A-3u");

    if ((request.getVersion() < 1) || (request.getVersion() > 2)) {
        throw new IllegalArgumentException("invalid version");
    }


    PDFAConformanceLevel pdfaConformanceLevel;
    switch (request.getConformanceLevel()) {
        case "BASIC":
            pdfaConformanceLevel = PDFAConformanceLevel.BASIC;
            break;
        case "ACCESSIBLE":
            pdfaConformanceLevel = PDFAConformanceLevel.ACCESSIBLE;
            break;
        case "UNICODE":
            pdfaConformanceLevel = PDFAConformanceLevel.UNICODE;
            break;
        default:
            throw new IllegalArgumentException("invalid level");
    }

    System.out.println(Arrays.toString(request.getPdf().getBytes(StandardCharsets.UTF_8)));
    byte[] xmlData = request.getXml().getBytes(StandardCharsets.UTF_8);
    byte[] pdfData = Base64.getDecoder().decode(request.getPdf().getBytes(StandardCharsets.UTF_8));


    ZUGFeRDExporterFromA1 ze = new ZUGFeRDExporterFromA1()
            .setProducer("Mustang API")
            .setCreator("Creator ME")
            .setZUGFeRDVersion(request.getVersion())
            .setConformanceLevel(pdfaConformanceLevel)
            .load(pdfData);
    ze.attachFile("factur-x.xml", xmlData, "text/xml", "Data");
    ze.setXML(xmlData);

    log.debug("Attaching ZUGFeRD-Data");
    ze.disableAutoClose(true);
    ze.export(output);
    byte[] bytes = output.toByteArray();
    InputStream inputStream = new ByteArrayInputStream(bytes);

    byte[] pdfBytes = IOUtils.toByteArray(inputStream);

    try {
        Utils.facturxValidator(request.getXml());
    } catch (Exception e) {
        e.printStackTrace();
    }

    String encoded = Base64.getEncoder().encodeToString(pdfBytes);
    return new FxResponse("OK", encoded);
}

I do retrieve a PDF as output but i have errors while validating the PDF.

On the other hand, my XML is fully valid

I tried to check if pdf was compliant or not to and I also tried mustang cli to check the ouput. I do have the following failures:

My questions are the following :

  1. How can I solve those failure
  2. Are those errors have impact on my facturX ? I do validated them on a test site, It's not on production
Solution

  • I noticed that i forgot to set facturx profile, for example, EXTENDED:

    ZUGFeRDExporterFromA1 ze = new ZUGFeRDExporterFromA1()
        .setProducer("Mustang API")
        .setCreator("Creator ME")
        .setProfile("EXTENDED");
        .setZUGFeRDVersion(request.getVersion())
        .setConformanceLevel(pdfaConformanceLevel)
        .load(pdfData);
ze.attachFile("factur-x.xml", xmlData, "text/xml", "Data");
ze.setXML(xmlData)

    Available values are the following:

    {"MINIMUM", new Profile("MINIMUM", "urn:factur-x.eu:1p0:minimum")},
{"BASICWL", new Profile("BASICWL", "urn:factur-x.eu:1p0:basicwl")},
{"BASIC", new Profile("BASIC", "urn:cen.eu:en16931:2017#compliant#urn:factur-x.eu:1p0:basic")},
{"EN16931", new Profile("EN16931", "urn:cen.eu:en16931:2017")},
{"EXTENDED", new Profile("EXTENDED", "urn:cen.eu:en16931:2017#conformant#urn:factur-x.eu:1p0:extended")},
{"XRECHNUNG", new Profile("XRECHNUNG", "urn:cen.eu:en16931:2017#compliant#urn:xoev-de:kosit:standard:xrechnung_2.1")}

    It works fine now !
