Remove ns2 prefix from xml using jaxb while marshalling

Question

I am performing marshalling using jaxB and xml is generated, but the issue is that there is "ns2" prefix in the root element of xml. I want to remove this prefix "ns2" from the generated xml while marshalling using jaxb.

I have made changes in package-info.java by putting the prefix as "" for the particular namespaceURI, so in that case instead of ns2 it becomes ns3, and my issue remained same.

I have also tried using NamespacePrefixMapper and same thing is happening with that as well (instead of ns2 it becomes ns3).

I want xml as below-

<?xml version="1.0" encoding="UTF-8"?>
<Document
    xmlns="urn:iso:std:iso:20022:tech:xsd:pacs.008.001.02"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="urn:iso:std:iso:20022:tech:xsd:pacs.008.001.02 pacs.008.001.02.xsd">
<FIToFICstmrCdtTrf>
        .....
</FIToFICstmrCdtTrf>
</Document>

But this is wat I am getting -:

 <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
 <ns3:Document xsi:schemaLocation="urn:iso:std:iso:20022:tech:xsd:pacs.008.001.02 
 pacs.008.001.02.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xmlns:ns3="urn:iso:std:iso:20022:tech:xsd:pacs.008.001.02">
 <ns3:FIToFICstmrCdtTrf>
 .....
 </ns3:FIToFICstmrCdtTrf>
 </ns3:Document>

Please have a look at my code-

1. Demo Code

    jaxbContext = JAXBContext.newInstance(/*my class*/); Marshaller marshaller = jaxbContext.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); StringWriter stringWriter = new StringWriter(); marshaller.setProperty(Marshaller.JAXB_SCHEMA_LOCATION, "urn:iso:std:iso:20022:tech:xsd:pacs.008.001.02 pacs.008.001.02.xsd"); marshaller.marshal(document, stringWriter);

2. package-info.java

    @javax.xml.bind.annotation.XmlSchema (namespace = "urn:iso:std:iso:20022:tech:xsd:pacs.008.001.02", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED, xmlns = { @javax.xml.bind.annotation.XmlNs(prefix="xsi", namespaceURI="http://www.w3.org/2001/XMLSchema-instance"), @javax.xml.bind.annotation.XmlNs(prefix="", namespaceURI="urn:iso:std:iso:20022:tech:xsd:pacs.008.001.02") } )

3. Root element

   @XmlRootElement(name="Document") @XmlAccessorType(XmlAccessType.NONE) @XmlType(name = "Document", propOrder = { "fiToFICstmrCdtTrf" }) @XmlSeeAlso({ DocumentEPC12216SCTINSTIB2019V10 .class }) @ToString public class Document extends ISODocument { @XmlElement(name = "FIToFICstmrCdtTrf", required = true) protected FIToFICustomerCreditTransferV02 fiToFICstmrCdtTrf; public FIToFICustomerCreditTransferV02 getFIToFICstmrCdtTrf() { return fiToFICstmrCdtTrf; } public void setFIToFICstmrCdtTrf(FIToFICustomerCreditTransferV02 value) { this.fiToFICstmrCdtTrf = value; } }

I tried various solutions for this but unfortunately none of them worked. Please let me know if anyone knows the solution, it would be very helpful for me.

Thanks in advance.!
