HashMap<String, Object> map = new HashMap<String, Object>();
JSONObject jsonObject = net.sf.json.JSONObject.fromObject(values);

Iterator keyIter = jsonObject.keys();
String key;
Object value;
while( keyIter.hasNext())
{
    key = (String)keyIter.next();
    value = jsonObject.get(key);
    map.put(key,value);
}
