I'm sorry, it seems Document.Factory.createNamespace() works slightly
different from new Namespace(). So instead of null namespace prefix
use empty string:
Namespace ns = documentFactory.createNamespace("",
"http://www.w3.org/2005/Atom";);
Following code works for me:
public static void main(String[] args) {
DocumentFactory documentFactory = new DocumentFactory();
Namespace ns =
documentFactory.createNamespace("","http://www.w3.org/2005/Atom";);
Element el = documentFactory.createElement(QName.get("root", ns));
Document document = documentFactory.createDocument(el);
System.out.println(document.asXML());
}
Output of this code is:
<?xml version="1.0" encoding="UTF-8"?>
<root xmlns="http://www.w3.org/2005/Atom"/>
