Java: Marshalling Object -- Removing extra ns2 annotation in xml
Solution 1
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>
Solution 2
add to xsd schema definition elementFormDefault and attributeFormDefault:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" ...
elementFormDefault="qualified" attributeFormDefault="unqualified" ... >
Solution 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.

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. Is there any way to get rid of the extra namespace annotation (i.e. ns2)
This is an example of the xml I receive from marshalling.
<?xml version="1.0" encoding="UTF-8" standalone="yes"> <root xmlns:ns2="http://www.something.com/something"> <ns2:food>steak</ns2:food> <ns2:beverage>water</ns2:beverage> </root>
What I want is something like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"> <root xmlns="http://www.something.com/something"> <food>steak</food> <beverage>water</beverage> </root>
This is what my Java code is doing:
JAXBContext context = JAXBContext.newInstance("com.schema"); JAXBElement<FoodSchema> element = new JAXBElement<FoodSchema> (new QName("FoodSchema"), Food.class, foodSchema); Marshaller marshaller = context.createMarshaller(); OutputStream os = new FileOutputStream(object.getFilePath()); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); marshaller.marshal(element, os);
Any help is much appreciated! Thanks!

user459811 over 12 yearsPerfect! I didn't have to add the package info annotation tag in order for it to work. Adding the extra schema namespace location in the QName was enough. Thanks again!

viruskimera over 6 yearsThis helped me, I was sending a different URI than the defined in the schema and it was causing the resultXMLstring to have another namespace
