Keep the order of the JSON keys during JSON conversion to CSV

I am using the JSON library provided here http://www.json.org/java/index.html to convert a json string I have to CSV.
But the problem I have is, the order of the keys is lost after conversion.

This is the conversion code:

JSONObject jo = new JSONObject(someString);
JSONArray ja = jo.getJSONArray("items");
String s = CDL.toString(ja);

This is the content of "someString":


This is the result:


While what I expect is to keep the order of the keys:


Is there any way I can have this result using this library? If not, is there any other library that will provide the capability to keep the order of keys in the result?

I used the JSON.simple library from here https://code.google.com/p/json-simple/ to read the JSON string to keep the order of keys and use JavaCSV library from here http://sourceforge.net/projects/javacsv/ to convert to CSV format.
