JAXB Unmarshalling not working. Expected elements are (none)

Question

I am trying to unmarshal an XML.

This is what my XML looks like

<DeviceInventory2Response xmlns="http://tempuri.org/">
<DeviceInventory2Result xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
  <Obj123 xmlns="">
     <Id>1</Id>
     <Name>abc</Name>
  </Obj123>
  <Obj456 xmlns="">
  .
  .
  .

I am trying to get Id and Name under Obj123. However when I run my unmarshal command I get the following error.

An Error:  javax.xml.bind.UnmarshalException: unexpected element (uri:"http://tempuri.org/", local:"DeviceInventory2Response"). Expected elements are (none)

My code looks like this in the main class:

Obj123 myObj123 = (Obj123) unmarshaller.unmarshal(inputSource);

And my class for Obj123 looks like this:

package com.myProj.pkg;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlElementWrapper;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;


@XmlRootElement(name="Obj123")
public class Obj123 {

  private String Id;
  private String Name;

  public String getId() {
    return Id;
  }

  public String getName() {
    return Name;
  }
}

I thought by setting my XMLRootElement that I should be able to skip the first 2 lines of my XML but that doesn't seem to be happening. Any ideas?

Edit:

This is how my JAXB Context is made:

JAXBContext jaxbContext = JAXBContext.newInstance();
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
Obj123 obj123 = (Obj123) unmarshaller.unmarshal(xmlStreamReader);

I solved the problem by adding

@XmlRootElement(name="abc_xxx") to the Root class.
(where abc_XXX is the root tag of your XML)

The JAXB classes generated by eclipse didn't add this annotation to my root class.
