javax.xml.bind.UnmarshalException converting xml to java object

Question

My application's config file that I load, myconfig.app:

<?xml version="1.0" encoding="UTF-8"?>
<application
  xmlns="http://www.example.com/com/code/app"
  authentication="form">

  <dummies>
    <dummy id="dummy1"/>
  </dummies>

</application>

Application.java

package com.code.custom;

import java.io.Serializable;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlRootElement;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = Application.XML_ELEMENT)
public class Application implements Serializable {

  public static final String XML_ELEMENT = "application";

  @XmlAttribute(name = "authentication")
  protected Boolean authentication;

  public Application() {}

  public Boolean getAuthentication() {
    return authentication;
  }
}

Loading of file content:

InputStream inputStream = ..

JAXBContext context = JAXBContext.newInstance(Application.class);

Unmarshaller unmarshaller = context.createUnmarshaller();

Application obj = (Application) unmarshaller.unmarshal(inputStream);

Error:

unexpected element (uri:"http://www.example.com/com/code/app", local:"application"). Expected elements are <{}application>
