Internal Server Error Exception from Facebook Graph API

I am trying to fetch campaign,ad level information from Facebook Using Graph API.
Campaign level information is getting with zero error for all accounts.
But for the Ad Level info, I am not getting the entire data. The API returns only 50. Remaining ads are getting with an exception called "Internal Server Error".
I've been getting this problem all day for one particular account. Every other Account works fine.
Below is the HTTP response:
response = (okhttp3.Response) Response{protocol=http/1.1, code=500, message=Internal Server Error,
url=https://graph.facebook.com/v3.3/act_fbAccountId/ads?access_token=myAccessToken&fields=%5B%22account_id%22%2C%22campaign_id%22%2C%22adset_id%22%2C%22id%22%2C%22bid_amount%22%2C%22name%22%2C%22status%22%2C%22preview_shareable_link%22%5D&limit=25&after=QVFIUkFzZAVdONXEwMXc5NjlOWURwczRQN0V3QW12NndRa0I4ZAUxsSjNkZA0FTRHR1U1dnaTQ5MTh2QnJ3bzNwWkNPd21jbC1tbjRmZAF81WVBsc0txaERCMHVn}

How do i parse large json files with json.simple?

I am new to JSON and I am learning using the json.simple library. I try to parse a large json file, but all i get is “OutOfMemoryError: GC overhead limit exceeded”. How can i parse large json files?
this is my code:
private static void fillPublications() throws FileNotFoundException, IOException, SQLException {
JSONParser parser = new JSONParser();
try {
String username = System.getProperty("user.name");
String filename = "Datenbank";
Object jsonData = parser.parse(new FileReader("C:\\Users\\" + username + "\\Desktop\\JSON\\" + filename + ".json"));
ArrayList<String[]> list = new ArrayList<String[]>();
JSONArray jsonArray = (JSONArray) jsonData;
Iterator iterator = jsonArray.iterator();
String name = "";
Integer count = 0;
while (iterator.hasNext()) {
String[] database = new String[11];
JSONObject obj = (JSONObject) iterator.next();
if(obj.containsKey("title")){
database[0] = (String) obj.get("title");
}
if(obj.containsKey("year")){
database[1] = obj.get("year").toString();
}
if(obj.containsKey("keywords")){
JSONArray keywords = (JSONArray) obj.get("keywords");
Iterator<String> i = keywords.iterator();
String key = "";
while (i.hasNext()) {
key = key + i.next() + "#";
}
if(key.length() > 0 && key.charAt(key.length()-1)=='#'){
key = key.substring(0, key.length()-1);
}
database[2] = key;
}
if(obj.containsKey("pages")){
database[3] = (String) obj.get("pages");
}
if(obj.containsKey("volume")){
database[4] = (String) obj.get("volume");
}
if(obj.containsKey("abstract")){
database[5] = (String) obj.get("abstract");
}
if(obj.containsKey("identifiers")){
JSONObject identifiers = (JSONObject) obj.get("identifiers");
database[6] = (String) identifiers.get("doi");
}
if(obj.containsKey("type")){
database[8] = (String) obj.get("type");
}
if(obj.containsKey("authors")){
JSONArray arr = (JSONArray) obj.get("authors");
Iterator i = arr.iterator();
while(i.hasNext()){
JSONObject authorObject = (JSONObject) i.next();
name = name + (String) authorObject.get("first_name") + " " + (String) authorObject.get("last_name") + "#";
}
if(name.length() > 0 && name.charAt(name.length()-1)=='#'){
name = name.substring(0, name.length()-1);
}
database[10] = name;
}
list.add(database);
}
System.out.println(Arrays.toString(list.get(0)));
}catch (Exception e) {
System.err.println(e);
}
}
and this is what i get:

How to get Json data

I have a json array like this
{
"success":"true",
"crops": {
"Brinjal":[---varieties of brinjal---],
"apple":[---varieties of apple---],
.................
.................
}
}
So i have got the complete crops using.....
JSONObject jsonObject;
jsonObject.getString("crops")
but i actually need to create two arrays like
String[] crops = {"Brinjal","apple"};
String[] varities = {"---Brinjal Varities---","---apple varities---"};
how can I generate these two arrays
if i generate "crops" then i can generate other array....
so how can i generate the "crops"...

You should do:
JSONObject obj = new JSONObject(jsonStringResp);
JSONObject cropsObj = obj.getJSONObject("crops");
JSONArray arr1 = subObject.getJSONArray("Brinjal");
Then you iterate over the JSON array and create the String array.
Hope it helps you.

public static void main(String[]args){
String joson = "{\n" +
" \"success\":\"true\",\n" +
" \"crops\": {\n" +
" \"Brinjal\":[---varieties of brinjal---],\n" +
" \"apple\":[---varieties of apple---],\n" +
" .................\n" +
" .................\n" +
" }\n" +
"}";
List<Object> apple = new ArrayList<Object>();
List<Object> Brinjal = new ArrayList<Object>();
apple.add("---varieties of apple---");
Brinjal.add("---varieties of brinjal---");
Map<String,Object> mapF = new HashMap<String,Object>();
Map<String,Object> mapS = new HashMap<String,Object>();
mapS.put("Brinjal", Brinjal);
mapS.put("apple", apple);
mapF.put("success", "true");
mapF.put("crops",mapS );
JSONObject obj = new JSONObject().fromObject(mapF);
System.out.println(obj);
JSONObject objF = obj.getJSONObject("crops");
String[] ListF = {};
String str = objF.keySet().toString();
String strF = str.substring(1, str.length()-1);
ListF = strF.split(", ");
List<Object> lsitF = new ArrayList<Object>();
for(int i = 0;i<ListF.length;i++){
lsitF.add(objF.get(ListF[i]));[enter image description here][1]
}
System.out.println(str);
System.out.println(lsitF.toString());
}
Hope it helps you.

Try this:
String joson = "{\n" +
" \"success\":\"true\",\n" +
" \"crops\": {\n" +
" \"Brinjal\":[---varieties of brinjal---],\n" +
" \"apple\":[---varieties of apple---],\n" +
" .................\n" +
" .................\n" +
" }\n" +
"}";
List<String> whereCrops = new ArrayList<String>();
List<String> whereVarities = new ArrayList<String>();
String[] crops;
String[] varities;
ArrayList<String> contentKey = new ArrayList<String>();
try {
JSONObject myObject = new JSONObject(joson);
JSONObject jsonCrops = myObject.getJSONObject("crops");
Iterator<String> iter = jsonCrops.keys();
while (iter.hasNext()) {
String key = iter.next();
whereCrops.add(key);
Log.e("inningskey", key);
try {
JSONArray array = jsonCrops.getJSONArray(key);
whereVarities.add(array.toString());
} catch (JSONException e) {
// Something went wrong!
}
}
// here ! you need convert whereCrops to crops
} catch (JSONException e) {
e.printStackTrace();
}
}

Rally REST API cannot find an existing workspace

i am using following piece of code to query for workspace. But apparently, if the workspace is not set as default, this query fails.
How can I successfully query for a workspace which is not my default workspace?
Thanks.
try{
QueryRequest proj1 = new QueryRequest("Workspace");
proj1.setFetch(new Fetch("Name"));
proj1.setQueryFilter(new QueryFilter("Name", "=",args[2]));
QueryResponse proj2 = batman.query(proj1);
Wspace_ref = proj2.getResults().get(0).getAsJsonObject().get("_ref").getAsString();
System.out.println("Workspace found.");
}catch (IndexOutOfBoundsException e){
System.out.println("Workspace Not Found.");
System.exit(1);
}

Since by default Rally REST queries are workspace-scoped, to obtain an enumeration of Workspaces, you need to query the Subscription object and then pull its Workspace collection.
Here's a quick example:
public class RestExample_QueryWorkspacesAndProjects {
public static void main(String[] args) throws URISyntaxException, IOException {
// Create and configure a new instance of RallyRestApi
// Connection parameters
String rallyURL = "https://rally1.rallydev.com";
String wsapiVersion = "1.43";
String applicationName = "RestExample_QueryWorkspacesAndProjects";
// Credentials
String userName = "user#company.com";
String userPassword = "topsecret";
RallyRestApi restApi = new RallyRestApi(
new URI(rallyURL),
userName,
userPassword);
restApi.setWsapiVersion(wsapiVersion);
restApi.setApplicationName(applicationName);
//Read Subscription
QueryRequest subscriptionRequest = new QueryRequest("Subscriptions");
subscriptionRequest.setFetch(new Fetch("Name", "SubscriptionID", "Workspaces", "Name"));
QueryResponse subscriptionQueryResponse = restApi.query(subscriptionRequest);
JsonArray subscriptionQueryResults = subscriptionQueryResponse.getResults();
JsonElement subscriptionQueryElement = subscriptionQueryResults.get(0);
JsonObject subscriptionQueryObject = subscriptionQueryElement.getAsJsonObject();
String subID = subscriptionQueryObject.get("SubscriptionID").toString();
System.out.println("Read Subscription: " + subID);
// Grab Workspaces Collection
JsonArray myWorkspaces = subscriptionQueryObject.get("Workspaces").getAsJsonArray();
// Initialize Project counter
int numberProjects = 0;
for (int i=0; i<myWorkspaces.size(); i++) {
JsonObject workspaceObject = myWorkspaces.get(i).getAsJsonObject();
String workspaceRef = workspaceObject.get("_ref").getAsString();
GetRequest workspaceRequest = new GetRequest(workspaceRef);
workspaceRequest.setFetch(new Fetch("Name", "Projects"));
GetResponse workspaceResponse = restApi.get(workspaceRequest);
JsonObject workspaceObj = workspaceResponse.getObject();
String workspaceName = workspaceObj.get("Name").getAsString();
System.out.printf("Workspace %d ==> %s\n", i, workspaceName);
JsonArray myProjects = workspaceObj.get("Projects").getAsJsonArray();
for (int j=0; j<myProjects.size(); j++)
{
JsonObject projectObject = myProjects.get(j).getAsJsonObject();
String projectRef = projectObject.get("_ref").getAsString();
GetRequest projectRequest = new GetRequest(projectRef);
projectRequest.setFetch(new Fetch("Name"));
GetResponse projectResponse = restApi.get(projectRequest);
JsonObject projectObj = projectResponse.getObject();
String projectName = projectObj.get("Name").getAsString();
System.out.printf("==> Project %d ==> %s\n", j, projectName);
numberProjects++;
}
}
String numberWorkspacesStr = String.valueOf(myWorkspaces.size());
String numberProjectsStr = String.valueOf(numberProjects);
System.out.println("Total Workspaces: " + numberWorkspacesStr);
System.out.println("Total Projects: " + numberProjectsStr);
restApi.close();
}
