Paring json string in java with javax.json

My ajax passed a json array that looks like this:

 {"formData":[{"cusID":"2"},{"empID":"1"}],"invoice":578416969}

I am trying to get the data using javax.json library.

JSONObject jsonObj = new JSONObject(jasonString);

I am able to grab the value of invoice:

Integer invoiceNum = (Integer) jsonObj.get("invoice");

But I am unable to grab the value of cusID and empID, by doing the following:

Integer cusId = Integer.parseInt((String) jsonObj.get("cusID"));
Integer empId = Integer.parseInt((String) jsonObj.get("empID"));

Error message:org.json.JSONException: JSONObject["cusID"] not found.

What did I do wrong? I am open to suggestions,if you have a better way of handling this json data, I am willing to use it.

You can using Gson() library. (com.google.gson.Gson) It makes you simple.

 JsonArray formData = jsonElement.getAsJsonObject().get("formData").getAsJsonArray();
 Integer cusId = formData.get(0).getAsJsonObject().get("cusID").getAsInt();
 Integer empId = formData.get(1).getAsJsonObject().get("empID").getAsInt();

cusID is actually an attribute of the first object in the array formData:

jsonObj.getJsonArray("formData").getJsonObject(0).get("cusID");

should do the trick.

First you have to get formData as an array, after that get the first element and get custId, after that get the second element and get empID.
