Java: Marshalling Object — Removing extra ns2 annotation in xml

Question

I am trying to marshall data within an object into an xml file based on a defined schema. However when I print out the xml file, I recieve extra annotations on the xml tags.

Answer 1

add to xsd schema definition elementFormDefault and attributeFormDefault:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" ...
elementFormDefault="qualified" attributeFormDefault="unqualified" ... >

Answer 2

By adding a namespace URI ("http://www.something.com/something") to the QName used to construct the JAXB element, and leveraging the package level @XmlSchema annotation will get you the namespace qualification that you are looking for:

package-info

@XmlSchema(
    namespace="http://www.something.com/something", 
    elementFormDefault=XmlNsForm.QUALIFIED)
package forum7014746;

import javax.xml.bind.annotation.*;

Food

package forum7014746;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Food {

    private String food;
    private String beverage;

    public String getFood() {
        return food;
    }

    public void setFood(String food) {
        this.food = food;
    }

    public String getBeverage() {
        return beverage;
    }

    public void setBeverage(String beverage) {
        this.beverage = beverage;
    }

}

Demo

package forum7014746;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBElement;
import javax.xml.bind.Marshaller;
import javax.xml.namespace.QName;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jaxbContext = JAXBContext.newInstance(Food.class);

        Food foodSchema = new Food();
        foodSchema.setFood("steak");
        foodSchema.setBeverage("water");

        JAXBElement<Food> element = new JAXBElement<Food> (new QName("http://www.something.com/something","FoodSchema"), Food.class, foodSchema);

        Marshaller marshaller = jaxbContext.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(element, System.out);
    }

}

Output

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<FoodSchema xmlns="http://www.something.com/something">
    <beverage>water</beverage>
    <food>steak</food>
</FoodSchema>

Answer 3

Thanks for answer. Just to give sample code before:

 marshaller.marshal(new  JAXBElement(new QName(**""**,"Document"),Document.class,swiftDoc), sw);

after:

marshaller.marshal(new  JAXBElement(new QName(**"http://www.w3.org/2001/XMLSchema**","Document"),Document.class,swiftDoc), sw);

and extra "ns:" was removed.
