JAXB Fragment Marshal w/o namespace

Question

I\'m using the JAXB_FRAGMENT property for my marshaller to marshal at the WorkSet level. The problem is that when I marshal it\'s giving the WorkSet element the xmlns attribute

Assuming you want the default namespace for your document to be http://www.namespace.com, you could do the following:

Demo

The XMLStreamWriter.setDefaultNamespace(String) and XMLStreamWriter.writeNamespace(String, String) methods will be used to set and write the default namespace for the XML document.

package forum9297872;

import javax.xml.bind.*;
import javax.xml.stream.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        XMLStreamWriter writer = XMLOutputFactory.newFactory().createXMLStreamWriter(System.out);
        writer.setDefaultNamespace("http://www.namespace.com");

        JAXBContext jc = JAXBContext.newInstance(WorkSet.class);
        Marshaller m = jc.createMarshaller();
        m.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);

        writer.writeStartDocument();
        writer.writeStartElement("http://www.namespace.com", "Import");
        writer.writeNamespace("", "http://www.namespace.com");
        writer.writeStartElement("WorkSets");

        m.marshal(new WorkSet(), writer);
        m.marshal(new WorkSet(), writer);

        writer.writeEndDocument();
        writer.close();
    }

}

WorkSet

My assumption is that you have specified namespace information in your JAXB model.

package forum9297872;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="WorkSet", namespace="http://www.namespace.com")
public class WorkSet {

}

Output

Below is the output from running the demo code:
