Jaxb generated xml - problem with root element prefix

Question

I am trying to generate xml using jaxb. I created xsd and generated java classes. But when I generate xml, I am geeting prefix ns2 to the root tag, which I don\'t want.

If this is your class:

package example;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="report",namespace="urn:report")
public class Root {

    private String id;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

}

Then it makes sense that there is a prefix on the root element, because you have specified that the "root" element is namespace qualified and the "id" element is not.

If you add a package-info class to your model, you can leverate the @XmlSchema annotation:

@XmlSchema(
        namespace = "urn:report",
        elementFormDefault = XmlNsForm.QUALIFIED)
package example;

import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;

Then the JAXB implementation may choose to leverage the default namespace, but note now all of the elements are namespace qualified which may or may not match your XML schema:
