On it's official website you can download a alpha release of Mustang 2.
- Factur-X/ZUGFeRD 2 is now the default. In Mustangproject 1.x one had to select ZUGFeRD version 2 if that was desired, in Mustangproject 2 one now has to select ZUGFeRD version 1 if version 2 is not appropriate.
- Mustang is now available via Maven Central, which makes it even easier to use the Mustang library. Apart from making it easier in Maven because there is no longer the need to mention the custom repository, it also makes it possible to use Mustang in Gradle projects
- ZUGFeRD 2.1.1 is now supported with it's XRechnung "reference profile". The previous stable version, Mustang 1.7.8, only supported ZUGFeRD 2.1.
- There is now an experimental visualization feature and an improved experimental upgrade functionality from ZF1 XML to ZF2 XML.
- Mustang now supports percentual and absolute charges and allowances on both item and document level
- Mustang can now embed additional invoice-accompanying files like plans or worklists into the PDFs
- Additionally to the usual interface-based architecture there are now also classes for invoice, tradeparty etc., which makes it easier to develop in the Mustang library. Please feel free to have a look at it's tests on https://github.com/ZUGFeRD/mustangproject/blob/master/library/src/test/java/org/mustangproject/ZUGFeRD/ZF2PushTest.java.
- Mustang now includes a validator, which can check the syntactical correctness of an e-invoice. The validator component has previously been developed under the name ZUGFeRD and VeraPDF "ZUV". It is now mature enought to be merged into the Mustang mainstream project. ZUV already was the validator behind https://www.zugferd-community.net/de/open_community/validation with around 1,000 validations/month alone, supports ZUGFeRD 1 and ZUGFeRD 2 and can be used via commandline. Additionally, the Mustang validator now also supports XRechnung 2, can now also be used as library and supports validation of whole directory trees.
java -jar Mustang-CLI-2.0.0-alpha3.jar --action=combine embedds a XML into a PDF (A-1) file and exports as PDF/A-3
java -jar mustang-cli.jar --action=extract extracts XML from a ZUGFeRD file and
java -jar mustang-cli.jar --action=validate validates XML or PDF files.
java -jar mustang-cli.jar --help still outputs the parameters which can be used
to for non-interactive (i.e., batch) processing.
The source file parameter for validation changed
from -f (ZUV) to the usual --source. The following
result codes apply:
| section | meaning |
|---|---|
| 1 | file not found |
| 2 | additional data schema validation fails |
| 3 | xml data not found |
| 4 | schematron rule failed |
| 5 | file too small |
| 6 | VeraPDFException |
| 7 | IOException PDF |
| 8 | File does not look like PDF nor XML (contains neither %PDF nor <?xml) |
| 9 | IOException XML |
| 11 | XMP Metadata: ConformanceLevel not found |
| 12 | XMP Metadata: ConformanceLevel contains invalid value |
| 13 | XMP Metadata: DocumentType not found |
| 14 | XMP Metadata: DocumentType invalid |
| 15 | XMP Metadata: Version not found |
| 16 | XMP Metadata: Version contains invalid value |
| 18 | schema validation failed |
| 19 | XMP Metadata: DocumentFileName contains invalid value |
| 20 | not a pdf |
| 21 | XMP Metadata: DocumentFileName not found") |
| 22 | generic XML validation exception |
| 23 | Not a PDF/A-3 |
| 24 | Issues in CEN EN16931 Schematron Check |
| 25 | Unsupported profile type |
| 26 | No rules matched, XML to minimal? |
| 27 | XRechnung Schematron Check |
We're now on maven central, please remove the old github repository. Additionally, the following changed
| What | old value | new value |
|---|---|---|
| Group id | org.mustangproject.zugferd | org.mustangproject |
| Artifact ID | mustang | library |
| Version | 1.7.8 | 2.0.0-alpha3 |
If you want you can also embed the validator in your software using validator as artifact ID. "validator" includes the library functionality but is >20 MB bigger due to it's dependencies.
ZF2 was possible with Mustang 1 but it is default in Mustang 2, so
you will need to .setZUGFeRDVersion(1) if you don't want ZUGFeRD 2 files.
In the commandline, all actions will have to be invoked via --action=, so --combine changes to --action=combine.
PDFattachZugferdFile is now called setTransaction and instead of
a ZUGFeRDExporterFromA1Factory the ZUGFeRDExporterFromA1 will now return a
a class implementing IZUGFeRDExporter instead of a ZUGFeRDExporter.
So
ZUGFeRDExporter ze = new ZUGFeRDExporterFromA1Factory().setZUGFeRDConformanceLevel(ZUGFeRDConformanceLevel.COMFORT).load(SOURCE_PDF)) {
changes to
IZUGFeRDExporter ze = new ZUGFeRDExporterFromA1().setZUGFeRDVersion(1).setZUGFeRDConformanceLevel(ZUGFeRDConformanceLevel.EN16931).load(SOURCE_PDF)) {
Instead of Profile.EXTENDED use Profiles.getByName("Extended").
If you want to use Profiles from older versions, please specify the version like
Profiles.getByName("Extended") for an Extended profile of ZF1.
The old Contact class has been corrected to TradeParty. The TradeParty class can now refer to a (human) Contact from the new Contact() class.
The importer can still be used like
ZUGFeRDImporter zi = new ZUGFeRDImporter(inputStream);
String amount = zi.getAmount();
but there is also the new invoiceImporter
ZUGFeRDInvoiceImporter zii=new ZUGFeRDInvoiceImporter(TARGET_PDF);
Invoice invoice=null;
try {
invoice=zii.extractInvoice();
} catch (XPathExpressionException | ParseException e) {
// handle Exceptions
}
assertFalse(hasExceptions);
// Reading ZUGFeRD
assertEquals("Bei Spiel GmbH", invoice.getOwnOrganisationName());
assertEquals(3, invoice.getZFItems().length);
assertEquals("400.0000", invoice.getZFItems()[1].getQuantity().toString());
assertEquals("160.0000", invoice.getZFItems()[0].getPrice().toString());
assertEquals("Heiße Luft pro Liter", invoice.getZFItems()[2].getProduct().getName());
assertEquals("LTR", invoice.getZFItems()[2].getProduct().getUnit());
assertEquals("7.00", invoice.getZFItems()[0].getProduct().getVATPercent().toString());
assertEquals("RE-20170509/505", invoice.getNumber());
SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");
assertEquals("2017-05-09",sdf.format(invoice.getIssueDate()));
assertEquals("Bahnstr. 42", invoice.getRecipient().getStreet());
assertEquals("88802", invoice.getRecipient().getZIP());
assertEquals("DE", invoice.getRecipient().getCountry());
assertEquals("Spielkreis", invoice.getRecipient().getLocation());
TransactionCalculator tc=new TransactionCalculator(invoice);
assertEquals(new BigDecimal("571.040000"),tc.getTotalGross());

A invoice like this
Invoice i = new Invoice().setDueDate(new Date()).setIssueDate(new Date()).setDeliveryDate(new Date()).setOwnOrganisationName(orgname).setOwnStreet("teststr").setOwnZIP("55232").setOwnLocation("teststadt").setOwnCountry("DE").setOwnTaxID("4711").setOwnVATID("0815").setRecipient(new Contact("Franz Müller", "0177123456", "fmueller@test.com", "teststr.12", "55232", "Entenhausen", "DE")).setNumber(number).addItem(new Item(new Product("Testprodukt", "", "C62", new BigDecimal(0)), amount, new BigDecimal(1.0)));
can be used to get XML
ZUGFeRD2PullProvider zf2p = new ZUGFeRD2PullProvider();
zf2p.generateXML(i);
String theXML = new String(zf2p.getXML());
or can also be used with setTransaction to generate invoice PDFs straight away.
The functionality is based on the XSLT file in library/src/main/resources/stylesheets/ZF1ToZF2.xsl, it can be accessed via
XMLUpgrader zmi = new XMLUpgrader();
String xml = zmi.migrateFromV1ToV2(xmlName);
Files.write(Paths.get(outName), xml.getBytes());
In case you don't want to access this functionality over the commandline you can use
ZUGFeRDVisualizer zvi = new ZUGFeRDVisualizer();
xml = zvi.visualize(sourceName);
Files.write(Paths.get("factur-x.xml"), xml.getBytes());
for the visualizer. The output requires a CSS and a javascript file which are in the jar's resources as (/src/main/resources/)xrechnung-viewer.css (/src/main/respurces/)xrechnung-viewer.js
The validator library also contains the functionality to read/write ZUGFeRD-invoices like the (smaller) library module.
