the javax.persistence.NonUniqueResultException error is typical of JPA not POI, add the code of your query.
Usually occurs when you use the getSingleResult () method and the query returns more than one result.

The request sent by the client was syntactically incorrect. Spring Backend

I stuck at this problem with Post Request, which gives me error 400 bad request, i have checked the JSON RequestBody via okHttpInterceptor by Retrofit and Json validated correctly. I don't know what's the problem with requestBody. it works with ModelAttribute though, but i want to pass data as requestBody.
This is my Spring Controller ->
#RequestMapping(value = "/updateProfile", method = RequestMethod.POST, consumes = "application/json", produces = "application/json")
#ResponseBody
public BasicResponse farmerUpdateProfile(#RequestBody UpdateFarmerRequest updateFarmerRequest, HttpServletRequest request) {
BasicResponse response = new BasicResponse();
// get authentication token and farmer ID from header
String requestAuthToken = (String) request.getHeader(MOBILE_AUTH);
String requestFarmerId = (String) request.getHeader(FARMER_ID);
// update farmer data, if id and AuthTokens are same...
// Validate Authentication Token
try {
if (!farmerMobileManager.validateAuthToken(requestFarmerId, requestAuthToken)) {
response.setErrorCode(ErrorCode.BAD_CREDENTIALS);
response.setResponse("Bad request error");
return response;
}
farmerMobileManager.updateFarmerRequest(updateFarmerRequest, response, requestFarmerId);
} catch (Exception ex) {
System.out.println(ex.getMessage());
response.setErrorCode(ErrorCode.INTERNAL_SERVER_ERROR);
response.setResponse("Error fetching prescriptions");

this is my RequestBody that i am sending in POSTMAN.
RequestBody ->
{
"farmer": {
"city": "",
"mandalName": "",
"stateName": "",
"villageName": "",
"countryCode": "+",
"cropData": [{
"crop": "RICE",
"cropAcres": 1.0,
"cropName": "RICE",
"cropYield": 2.0
}, {
"crop": "PADDY",
"cropAcres": 4.0,
"cropName": "PADDY",
"cropYield": 5.0
}
],
"cropId": "",
"districtId": "",
"farmerReferenceId": "",
"firstName": "",
"houseNumber": "",
"id": "",
"mandalId": "",
"phoneNumber": "",
"stateId": "",
"villageId": ""
}
}
The Data are not empty, but i am purposely not filling it for privacy purpose.

I have solved my problem, it was naming convention problem, as i was passing cropData as "cropData", while at server Side it was "CropData."

Thank for your help.
UPDATE: SOLVED
'Pesan' should be List<>

In your ResponseModel you define String pesan, while in the json file pesan is a List<QuestionModel>

make some changes in response model class like below ..
public class Response {
#SerializedName("kode")
private Integer kode;
#SerializedName("pesan")
private List<Pesan> pesan = null;
public Integer getKode() {
return kode;
}
public void setKode(Integer kode) {
this.kode = kode;
}
public List<Pesan> getPesan() {
return pesan;
}
public void setPesan(List<Pesan> pesan) {
this.pesan = pesan;
}
}
and also make one pesan pojo class.
public class Pesan {
#SerializedName("id_question")
private String idQuestion;
#SerializedName("id_user")
private String idUser;
#SerializedName("judul")
private String judul;
#SerializedName("waktu")
private String waktu;
#SerializedName("tanggal")
private String tanggal;
#SerializedName("jml_like")
private String jmlLike;
#SerializedName("aktif")
private String aktif;
public String getIdQuestion() {
return idQuestion;
}
public void setIdQuestion(String idQuestion) {
this.idQuestion = idQuestion;
}
public String getIdUser() {
return idUser;
}
public void setIdUser(String idUser) {
this.idUser = idUser;
}
public String getJudul() {
return judul;
}
public void setJudul(String judul) {
this.judul = judul;
}
public String getWaktu() {
return waktu;
}
public void setWaktu(String waktu) {
this.waktu = waktu;
}
public String getTanggal() {
return tanggal;
}
public void setTanggal(String tanggal) {
this.tanggal = tanggal;
}
public String getJmlLike() {
return jmlLike;
}
public void setJmlLike(String jmlLike) {
this.jmlLike = jmlLike;
}
public String getAktif() {
return aktif;
}

above code working only you provide json format in question if any error then pl provide full json from server given response.
because answer is based on question json format based.

How to deserialize a JSON Object in a multidimensional array

I have this JSON data and I would like to deserialize it with Android to get it as an object to use in my class.
I get this folowing error :
Could not read JSON: Unrecognized field "card_details"
[
{
"id": "9",
"cat_id": "CAT-8584ce02f180b57a8c6d66570f696e02",
"app_id": "null",
"status": "1",
"lft": "1",
"rgt": "2",
"parent_cat_id": "0",
"added_date": "2017-01-12 12:41:29",
"last_edit_date": "2017-01-12 12:46:09",
"language_id": "0",
"category_id": "CAT-8584ce02f180b57a8c6d66570f696e02",
"name": "Sport",
"description": "This is sport category",
"image": "notitia/USR-70903638005256656/app-content/cat-img-da1161af03df255a989f8df5fc2e15bd.png",
"tags": "",

"validity": "1"
}
}
]
Here is my AsyncTask to retrieve the data:
private class HttpRequestTaskCarte extends AsyncTask<Void,Void,Item[]> {
#Override
protected Item[] doInBackground(Void... params) {
try {
final String url = "http://domain.com/link.php?target=multi";
RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
Item[] greeting = restTemplate.getForObject(url, Item[].class);
return greeting;
} catch (Exception e) {
//Toast.makeText(getActivity(), "Error Loading !", Toast.LENGTH_SHORT).show();
Log.e("MainActivity", e.getMessage(), e);
}
return null;
}
protected void onPreExecute(){
progressDialog = new ProgressDialog(getActivity(),
R.style.AppTheme_Dark_Dialog);
progressDialog.setIndeterminate(true);
progressDialog.setMessage("chargement des elements...");
progressDialog.show();
}
#Override
protected void onPostExecute(Item[] greeting) {
Log.d("okokok",""+greeting.length);
progressDialog.dismiss();
}
}
And here is the class that I am using to deserialize:
public class Item {

JSONArray array=new JSONArray(your data);
JSONObject obj=array.getJSONObject(0);
JSONObject cardDetail=obj.getJSONObject("card_details");

Hii u can use the following code:
JSONArray jsonarray = new JSONArray(jsonStr);
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject jsonobject = jsonarray.getJSONObject(i);
String name = jsonobject.getString("name");
String url = jsonobject.getString("url");
}

Spark: Mapping RDD to RDD returning nullpointer Exception

In my logic, I am attempting to map a JDBCRDD - TopologyRDD over to a JavaBean of JavaRDD.
TopologyRDD.count() returns the CORRECT number of rows, so I know the data was loaded in correctly. I also mapped TopologyRDD to a List just to confirm the data was loaded in, and it loaded in the data just fine.
Problem: When mapping TopologyRDD to MODEL_TOPOLOGYRDD, the MODEL_TOPOLOGYRDD.count() action is returning a nullpointer exception error.

The only problem I can see with this code is if any line2[i] are null.
And if(line2[i].toString() == null) won't work because toString() never returns null for the Object class.
I see that you want any null values to become empty strings, so try this as your for-loop instead
for(int i = 0; i < line2.length; i++){
line2[i] = (line2[i] == null) ? "" : String.valueOf(line2[i]);
}
Note the use of String.valueOf, which altogether avoids the NullPointerException when trying to get the String value of objects.
