Spring xml in response via JAXB - spring

Question

I am using spring 3.1, and my application is already set up to send and receive data in json format. Now I need to provide one request API that should return the same data but in xml format.
Please help me with this stuff or tell what I am doing wrong. I tried JAXB, but instead of xml I receive "406 Not Acceptable".
My requests API:
/**
* Gets objects in json format
*/
#RequestMapping(value = "/objects/json", method = RequestMethod.GET)
#ResponseBody
public List<MyObjectTO> getAll() {
List<MyObjectTO> objectsList = new ArrayList<MyObjectTO>();
//forming objects
return objectsList;
}
/**
* Gets objects in xml format
*/
#RequestMapping(value = "/objects/xml", method = RequestMethod.GET,headers={"Accept=application/xml"})
#ResponseBody
public ResponseList getAll() {
ResponseList objectsList = new ResponseList ();
//the same formation
return objectsList;
}

My changes: Added message converters to AnnotationMethodHandlerAdapter and inserted JAXB marshaller. But after this got response "406 Not Acceptable":
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="alwaysUseFullPath" value="true"/>
<property name="messageConverters">
<list>
<ref bean="marshallingConverter" />

<property name="classesToBeBound">

I would appreciate any help, thanks.
UPDATE
ResponseList structure:
public class ResponseList {
private List<FirstLevel> firstLevelObjects;
public List<FirstLevel> getFirstLevelObjects() {
return firstLevelObjects;
}
public void setFirstLevelObjects(List<FirstLevel> firstLevelObjects) {
this.firstLevelObjects= firstLevelObjects;
}
}
FirstLevel structure:
public class FirstLevel {
List<SecondLevel> secondLevelObjects;
boolean isConditional;
String beforeStart;
ConditionType type;//enum object
//...getters and setters
}

I lost hope with Castor, so tried once more with JAXB. Changed post
with details for JAXB. The same issues - I got Not Acceptable when
trying to request xml. Can you help me?
All you should need to do for JAXB is to add an #XmlRootElement annotation to your ResponseList class.
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement
public class ResponseList {
private List<FirstLevel> firstLevelObjects;
public List<FirstLevel> getFirstLevelObjects() {
return firstLevelObjects;
}
public void setFirstLevelObjects(List<FirstLevel> firstLevelObjects) {
this.firstLevelObjects= firstLevelObjects;
}
}
