android2.2 package import json common abnormalities

I do a client on android http client to accept the return data. Get a String mess, the JSONobject.toString get.
Import java json common package (6) afterandroid parsing code as follows:
String mess = "{" loginuser ": [{" password ": " 123 ", " person ": {" address & quot;: " 4654 ", " id ": 1, " name ": " ttjxffda ", " phone ": " 1212 "}, " status ": 0, " username ": " ttjxtjx "}], " loginresult ": " success "} ";
JSONObject jsonObject = JSONObject.fromObject (mess);
String state = (String) jsonObject.get ("loginresult");
if (state.equals ("success")) {
JSONArray jsonArray = jsonObject.getJSONArray ("loginuser");
for (int i = 0; i JSONObject item = jsonArray.getJSONObject (i);
Libuser user = new Libuser ();
user.setUsername (item.getString ("username"));
user.setPassword (item.getString ("password"));
user.setStatus (item.getInt ("status"));
}

}
Unit Testing Times in android exception java.lang.IllegalArgumentException: already added: Lorg / apache / commons / collections / ArrayStack; project can not go wrong test

In java project through testing.

I know this is because of the introduction of duplicate packets, I deleted the commons-collections.jar (3.2) this package, the results reported could not find class exception:
case by: NoClassDefFoundError org.apache.commons.map.listOrderedMap.

Can not be resolved. Tangle. Seek expert advice

I have had the common sense that comes with android json class, but it will not mess parsing strings,
org.json.JSONException: Expected ':' after & quot at character 7 of {" loginuser ": [{" password ": " 123 ", & quot; person ": {" address ": " 4654 ", " id ": 1, " name ": " ttjxffda ", " phone ": " 1212 "}, " status ": 0, " username ": " ttjxtjx & quot;}], " loginresult ": " success "}

mess content code has. outprint result: {"loginuser": [{"password": "123", "person": {"address": "4654", "id": 1, "name": "ttjxffda", "phone": " 1212 "}," status ": 0," username ":" ttjxtjx "}]," loginresult ":" success "}

The code generated mess, Libuser There is a Person object.

Libuser loginuser = LibuserService.getLoginUser (user);
System.out.println (loginuser.toString ());
JSONObject jsonObject = new JSONObject ();
JSONObject item = new JSONObject ();
JSONArray jsonArray = new JSONArray ();
item.put ("username", loginuser.getUsername ());
item.put ("password", loginuser.getPassword ());
item.put ("status", loginuser.getStatus ());
jsonArray.element (loginuser);
jsonObject.put ("loginuser", jsonArray);
jsonObject.put ("loginresult", loginresult);
this.message = jsonObject.toString ();
System.out.println (message);

Their own investigation for a long time without a solution. Tangled ah, seeking expert advice.<-! Main posts under Banner (D4) -><-! Posts under the main text (D5) ->
