TO Return Map like structue you need to wrap it in Wrapper class.
Wrap your Map into JAXBMap
as shown below and return it.
package myexample;
import java.util.Map;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class JAXBMap<T, K> {
Map<T, K> map;
public Map<T, K> getMap() {
return map;
}
public void setMap(Map<T, K> map) {
this.map = map;
}
public JAXBMap(Map<T, K> map) {
super();
this.map = map;
}
public JAXBMap() {
super();
}
}
