No Prefix is geting added after adding the namespace context

[rajeev-jha1988]

final MapBasedNamespaceContext aNSContext = UBL21NamespaceContext.getInstance ().getClone ();
    aNSContext.clear();
    aNSContext.addDefaultNamespaceURI ("urn:oasis:names:specification:ubl:schema:xsd:Invoice-2");
    aNSContext.addMapping ("cac", CUBL21.XML_SCHEMA_CAC_NAMESPACE_URL);
    aNSContext.addMapping ("cbc", CUBL21.XML_SCHEMA_CBC_NAMESPACE_URL);
    aNSContext.addMapping ("cec", CUBL21.XML_SCHEMA_CEC_NAMESPACE_URL);
    aNSContext.addMapping ("ds", CXMLDSig.NAMESPACE_URI);

   // typeUBL21WriterBuilder.setMarshallerCustomizer( GenericJAXBMarshaller )
    typeUBL21WriterBuilder.setNamespaceContext( aNSContext );

By default its adding NS in XML

<?xml version="1.0" encoding="UTF-8"?>

Dummy Invoice number 2022-11-16Z 10 10 10 Z 10 VAT 10 1 10 Dependencies: implementation group: 'com.helger.ubl', name: 'ph-ubl21', version: '6.7.0' // https://mvnrepository.com/artifact/com.helger.ubl/ph-ubl21-codelists implementation group: 'com.helger.ubl', name: 'ph-ubl21-codelists', version: '6.7.0'

Hi @rajeev-jha1988 please post a bit more of your code.

You can btw. simplify your code if you like:

final MapBasedNamespaceContext aNSContext = new MapBasedNamespaceContext  ();
    aNSContext.addDefaultNamespaceURI ("urn:oasis:names:specification:ubl:schema:xsd:Invoice-2");
    aNSContext.addMapping ("cac", CUBL21.XML_SCHEMA_CAC_NAMESPACE_URL);
    aNSContext.addMapping ("cbc", CUBL21.XML_SCHEMA_CBC_NAMESPACE_URL);
    aNSContext.addMapping ("cec", CUBL21.XML_SCHEMA_CEC_NAMESPACE_URL);
    aNSContext.addMapping ("ds", CXMLDSig.NAMESPACE_URI);

It's important that you call .setNamespaceContext BEFORE you call write... or getAs... methods on the marshaller..

Hi @phax ,

here is code , UBL21WriterBuilder typeUBL21WriterBuilder = UBL21Writer .invoice() ;

    final MapBasedNamespaceContext aNSContext = new MapBasedNamespaceContext  ();
    aNSContext.addDefaultNamespaceURI ("urn:oasis:names:specification:ubl:schema:xsd:Invoice-2");
    aNSContext.addMapping ("cac", CUBL21.XML_SCHEMA_CAC_NAMESPACE_URL);
    aNSContext.addMapping ("cbc", CUBL21.XML_SCHEMA_CBC_NAMESPACE_URL);
    aNSContext.addMapping ("cec", CUBL21.XML_SCHEMA_CEC_NAMESPACE_URL);
    aNSContext.addMapping ("ds", CXMLDSig.NAMESPACE_URI);

    typeUBL21WriterBuilder.setNamespaceContext( aNSContext );

    // Write to disk
    final ESuccess eSuccess = typeUBL21WriterBuilder
        .setUseSchema (false)
        .setFormattedOutput (true)
        .write (aInvoice, new File("target/dummy-invoice.xml"));

[phax]

Please also look at #34 - it contains a solution for your problem. Eventually your file does not get written, because the content of aInvoice is not correct. What does ESuccess tell you - is it successful or not?

[rajeev-jha1988]

Hi @phax , Here is code which i am using now its giving success in ESuccess but still the prefix are dynamic like NS4,NS3 ... ` final String sCurrency = "SAR";

    // Create domain object
    final InvoiceType aInvoice = new InvoiceType ();

   // aInvoice.setUBLExtensions( ublExtensionsType );

    // Fill it
    aInvoice.setID ("Dummy Invoice number");
    aInvoice.setIssueDate ( PDTFactory.getCurrentXMLOffsetDateUTC ());

    final SupplierPartyType aSupplier = new SupplierPartyType ();
    aInvoice.setAccountingSupplierParty (aSupplier);

    final CustomerPartyType aCustomer = new CustomerPartyType ();
    aInvoice.setAccountingCustomerParty (aCustomer);

    final MonetaryTotalType aMT = new MonetaryTotalType ();
    aMT.setPayableAmount ( BigDecimal.TEN).setCurrencyID (sCurrency);
    aInvoice.setLegalMonetaryTotal (aMT);

    final InvoiceLineType aLine = new InvoiceLineType ();
    aLine.setID ("1");

    final ItemType aItem = new ItemType ();
    aLine.setItem (aItem);

    aLine.setLineExtensionAmount (BigDecimal.TEN).setCurrencyID (sCurrency);

    aInvoice.addInvoiceLine (aLine);

    {
        final TaxSubtotalType aTaxSubtotal = new TaxSubtotalType ();
        aTaxSubtotal.setTaxableAmount (BigDecimal.TEN).setCurrencyID (sCurrency);
        aTaxSubtotal.setTaxAmount (BigDecimal.TEN).setCurrencyID (sCurrency);

        final TaxCategoryType aTaxCategory = new TaxCategoryType ();
        final IDType aTCID = new IDType ();
        aTCID.setSchemeID ("UNCL5305");
        aTCID.setSchemeAgencyID ("6");
        aTCID.setValue ("Z");
        aTaxCategory.setID (aTCID);

        aTaxCategory.setPercent (BigDecimal.TEN);

        final TaxSchemeType aTaxScheme = new TaxSchemeType ();
        final IDType aTSID = new IDType ();
        aTSID.setSchemeID ("UNCL5305");
        aTSID.setSchemeAgencyID ("6");
        aTSID.setValue ("VAT");
        aTaxScheme.setID (aTSID);
        aTaxCategory.setTaxScheme (aTaxScheme);

        aTaxSubtotal.setTaxCategory (aTaxCategory);

        final TaxTotalType aTaxTotal = new TaxTotalType ();
        aTaxTotal.setTaxAmount (BigDecimal.TEN).setCurrencyID (sCurrency);
        aTaxTotal.addTaxSubtotal (aTaxSubtotal);
        aInvoice.addTaxTotal (aTaxTotal);
    }

    UBL21WriterBuilder<InvoiceType> typeUBL21WriterBuilder = UBL21Writer
        .invoice()
        ;

    final MapBasedNamespaceContext aNSContext = new MapBasedNamespaceContext  ();
    aNSContext.addDefaultNamespaceURI ("urn:oasis:names:specification:ubl:schema:xsd:Invoice-2");
    aNSContext.addMapping ("cac", CUBL21.XML_SCHEMA_CAC_NAMESPACE_URL);
    aNSContext.addMapping ("cbc", CUBL21.XML_SCHEMA_CBC_NAMESPACE_URL);
    aNSContext.addMapping ("cec", CUBL21.XML_SCHEMA_CEC_NAMESPACE_URL);
    aNSContext.addMapping ("ds", CXMLDSig.NAMESPACE_URI);

   // typeUBL21WriterBuilder.setMarshallerCustomizer( GenericJAXBMarshaller )
    typeUBL21WriterBuilder.setNamespaceContext( aNSContext );
   // typeUBL21WriterBuilder.getMarshallerCustomizer()

    // Write to disk
    final ESuccess eSuccess = typeUBL21WriterBuilder
        .setUseSchema (true)
        .setFormattedOutput (true)
        .write (aInvoice, new File("target/dummy-invoice.xml"));
    System.out.println(eSuccess.isSuccess ());`

I used your code, create a file and it looks good. In the above commit, the only thing I changed is to use getAsString (...) instead of write (....)

The output in my console is:

Hi @phax, I have checked, when I am using the Project test case it's generating the right XML but when I am using it as Gradle it's not getting generated.

Please check my sample project https://github.com/rajeev-jha1988/xml-parser-ksa/blob/main/src/main/java/org/example/CreateXMLFromScratch.java

[phax]

Sorry, I can't help you here. I don't know Gradle and I don't have the time. What I saw: a) Don't push the folders build or target to GitHub - they should be created on the flay b) It seems like your code is not called from the commandline. Is your "Main" class configured correctly?

[rajeev-jha1988]

Hi @phax , I checked it . looks like we need to add additional dependency to generate in above mention format , here are dependencies which I have added and after that its generated the XML with proper prefix define in class.

I am adding here to list all the mandatory dependencies for other if they faced same issue.

`

implementation group: 'com.helger.ubl', name: 'ph-ubl21', version: '6.7.0'

Thanks for your time

[phax]

Congrats :) Glad to hear that it worked for you and thanks for sharing the solution as well. Very helpful!
