Remove ns2 as default namespace prefix

Question

I have a file that is printed with a default namespace. The elements are printed with a prefix of ns2, I need this to be removed, how it is with my code:

<ns2:foo xmlns:ns2="http://namespace" />

how I want it to be:

<foo xmlns="http://namespace" />

this is how I have coded it, something which as I see it should be enough for the ns2 to go away:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:bar="http://namespace" targetNamespace="http://namespace"
    elementFormDefault="qualified">
...

the generated package-info turns out like this:

@javax.xml.bind.annotation.XmlSchema(namespace = "http://namespace", 
    elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.foo.bar;

I create the file like this:

JAXBContext jaxbContext = JAXBContext.newInstance(generatedClassesPackage);
Marshaller marshaller = jaxbContext.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
marshaller.marshal(new JAXBElement<Foo>(new QName("http://namespace", "Foo"),
Foo.class, rootFoo), outputStream);

generatedClassesPackage is the package where package-info.java and the elements are.

The Foo object is defined and has elements like this::

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "group"
})
@XmlRootElement(name = "Foo")
public class Foo {

    @XmlElement(name = "Group", required = true)
    protected List<Group> group;

Is it something I have missed? or have I misunderstood how this works?

Answer 1

All you need 2 do is when you open a new package select create package info in the package info add the following annotation or change it as needed

@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.sitemaps.org/schemas/sitemap/0.9", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED, xmlns = { @javax.xml.bind.annotation.XmlNs(namespaceURI = "http://www.sitemaps.org/schemas/sitemap/0.9", prefix = "") })

This will remove the ns2 prefix
