List jsonList = new ArrayList();
net.sf.json.JSONArray array = net.sf.json.JSONArray.fromObject(json);
for (Object object : array) {
    net.sf.json.JSONObject jsonStr = (net.sf.json.JSONObject)JSONSerializer.toJSON(object);
    Document jsnObject = Document.parse(jsonStr.toString()); 
    jsonList.add(jsnObject);
}
collection.insertMany(jsonList);
