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

Answer 2

Most likely you have multiple namespaces in the response. This will use the default convention of creating ns# namespace prefixes and one of them becomes the xmlns without a prefix. If you want to control this you can do the following:

NamespacePrefixMapper mapper = new NamespacePrefixMapper() {         public String getPreferredPrefix(String namespaceUri, String suggestion, boolean requirePrefix) {             if ("http://namespace".equals(namespaceUri) && !requirePrefix)                 return "";             return "ns";         }     };     marshaller.setProperty("com.sun.xml.bind.namespacePrefixMapper", mapper);     marshaller.mashal.... 

This will set the http://namespace as the default xmlns always and use ns# for all other namespaces when marshalling. You can also give them more descriptive prefixes if you want.
