XML to Object mapping

Having hard time to map..
Calling rest and rest return response in XML format..
Help with class mapping in Java Object (method)
<aname>
<bname>
<c id="2">
<cname call="yes" text="no" email="yes"/>
<acc>
<accinfo name="ax" addr="USA"/>
</acc>
</c>
</bname>
</aname>
how can i convert above xml in Java class?
Thank You!

I share solution:
If you use need dependency

"No suitable constructor found for type" and the type exists and has a default constructor

I am receiving this message in a new jersey 1.19.4 app that I am building:
No suitable constructor found for type [simple type, class javax.xml.bind.JAXBElement<com.objex.idms.idd.types.IDDModule>]: can not instantiate from JSON object (need to add/enable type information?)
at [Source: org.apache.catalina.connector.CoyoteInputStream#5a5e4ec1; line: 1, column: 2]
After much searching I have seen many posts that indicate this can be caused by a missing default constructor. However that doesn't seem to the the case here. Note I have tried this implementing "Serializable" with the same result. I am sure it's something simple but am just missing it.
Here is the class in question, any thoughts you might have would be appreciated.

passing custom object in retrofit2

i am trying to pass a custom object via retrofit2, and my question is that does the server writes my custom object to json automatically or do i have to write a php file for that. In the meanwhile I am posting successfully to the server but unable to write to json.
My aim is to write custom object to server, and write the contents of custom objects to json file.
Here is my Retrofit Api
public interface ApsaraCatalogAPI {
#GET("/apsaratrendz/data/apsara_json_document_v2.json")
Call<List<ApsaraCatalogModel>> getFeed();
#POST("/apsaratrendz/data/apsara_json_orders_document.json")
Call<Void> setOrder(#Body OrderModel orderModel);
}
Here is my calling api function
#Override
public void onClick(View v) {
int total = 0;
if(v.getId()==R.id.fabButtonCart && cartlist.size()!=0)
{
// get details from shared preferences
OrderModel orderModel = new OrderModel();
orderModel.setDate(getDate());
orderModel.setName("ssdfs");
orderModel.setEmail("sdf#gmail.com");
orderModel.setNoofitems(String.valueOf(cartlist.size()));
orderModel.setOrderno("32335");
orderModel.setPhone("9896566444");
for(int i=0; i<cartlist.size();i++){
Productdetail pd = new Productdetail();
pd.getSellingprice(String.valueOf(cartlist.get(i).getSellingPrice()));
pd.getPid(cartlist.get(i).getEANCode());
total += cartlist.get(i).getSellingPrice();
orderModel.getProductdetails().add(pd);
}
//
// now go for insertion using retrofit
requestData(orderModel);
Toast.makeText(getApplicationContext(), "Total Price : Rs."+total+"/-", Toast.LENGTH_LONG).show();
}else{
Toast.makeText(getApplicationContext(), "Cart is Empty", Toast.LENGTH_LONG).show();
}
}
And here is my service request for retrofit api, I am passing the newly created POJO OrderModel class.
private void requestData(OrderModel orderModel) {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(ENDPOINT)
.addConverterFactory(GsonConverterFactory.create())
.build();
ApsaraCatalogAPI service = retrofit.create(ApsaraCatalogAPI.class);
Call<Void> call = service.setOrder(orderModel);
call.enqueue(new Callback<Void>() {
#Override
public void onResponse(Call<Void> call, Response<Void> response) {
if(response.isSuccessful()){
Log.d("InApi","Yipppie");
}
}

}
public Map<String, Object> getAdditionalProperties() {

this.sellingprice = sellingprice;
}
public Map<String, Object> getAdditionalProperties() {
return this.additionalProperties;
}
public void setAdditionalProperty(String name, Object value) {
this.additionalProperties.put(name, value);
}
}

Retrofit generates the json based on your POJO and set it on the post payload.
So, in this case:
#POST("/apsaratrendz/data/apsara_json_orders_document.json")
Call<Void> setOrder(#Body OrderModel orderModel);
the body of the post will be a json representation of orderModel.
If you need to change the names of the atributtes generated in the json you can use SerializedName Annotation, its very useful:
public class OrderModel {
#SerializedName("other_name_for_json")
private String name;
Hope it helps.

Consuming Rest Service

I just started with rest services and i have read this https://spring.io/guides/gs/consuming-rest/. Then according to this tutorial i have a service to consume and display.
The service is a rest api and i get a json like that
{
"disclaimer": "1",
"license": "2",
"timestamp": 1458057661,
"base": "someValue",
"rates": {
"one": 3.673019,
"two": 68.449999,
"three": 124.168,
"four": 488.669996,
...,
...,
...
}
}
Then i have created 2 Java class like that
#JsonIgnoreProperties(ignoreUnknown = true)
public class Cur {
private String disclaimer;
private String license;
private String timestamp;
private String base;
private Rates rates;
public Cur() {
super();
}
///get/set
///tostring
}
#JsonIgnoreProperties(ignoreUnknown = true)
public class Rates {
public Rates(){
//// i am not sure here how should i get the rates value.
}
}
the problem is how do i fill the Rates class to get the data into variables so that later i can present the on view.
I use RestTemplate. Here is the test.It works but i have no rates value.
I think i need a Map because rates it's a collection.Any idea how to implement it.
#Test
public void getCurTest() {
String URL="some url";
String JSONTYPE="some json type";
String API="some id";
RestTemplate restTemplate = new RestTemplate();
Cur cur= restTemplate.getForObject(URL+JSONTYPE+API, Cur.class);
log.info("cur");
System.out.println(cur);
}

I had the same some years ago it's a little weird. Here what you can do.
First solution
The simple way is
CloseableHttpClient httpclient = HttpClients.createDefault();
HttpGet httpget = new HttpGet("your rest service api");
CloseableHttpResponse response = httpclient.execute(httpget);
try {
HttpEntity entity = response.getEntity();
if (HttpStatus.SC_OK == response.getStatusLine().getStatusCode()) {
String responseValue = EntityUtils.toString(entity);
System.out.println(responseValue);
} else {
// log error
}
} finally {
response.close();
}
}
you can then get everything as a String and with regex parse it and get what you want.
Second solution
you can save all your rest to a database as it is. Use mongodb for faster.
Then you can get it form there to a class and use it.
Third solution
use this tool http://www.jsonschema2pojo.org/ just paste your json and it will create your java classes to use them. You can choose what ever you want to add. This will create your classes then you can use them.
Here for your convenience.

/**
*
* #return
* The four
*/
#JsonProperty("four")
public Double getFour() {
return four;
}
/**
*
* #param four
* The four
*/
#JsonProperty("four")
public void setFour(Double four) {
this.four = four;
}
#Override
public String toString() {
return ToStringBuilder.reflectionToString(this);
}
#JsonAnyGetter
public Map<String, Object> getAdditionalProperties() {
return this.additionalProperties;
}
#JsonAnySetter
public void setAdditionalProperty(String name, Object value) {
this.additionalProperties.put(name, value);
}
}
Then you can use it as you want.
I hope all this helps. Take care.

The way your JSON is, to get the Rates populed your class should look like this.
public class Cur {
private String disclaimer;
private String license;
private Integer timestamp;
private String base;
private Rates rates;
}
public class Rates {
private Double one;
private Double two;
private Double three;
private Double four;
//This would be better but the JSON dosnt fit this
//private Map<String, Double> rates;
}
Which API are you triyng to use?

Java How create a set of object with two classes?

I have a logical problem to understand, how create a private set of inhabitant object. Here my two classes:
package main;
import java.util.Set;
/**
* #author
* #version 0.1
*
*/
public class City {
private String name;
/**
*HERE is my Problem*/
private Set<Inhabitants> Inhabitants {
}
/**
* standard cunstructor
*/
public City(String n, ) {
setName(n);
}
/**
* Search a particular name of inhabitant
* #return object of inhabitant
*/
static Set<Inhabitants> Search(){
return inhabitants;
}
/**
* Creates a inhabitant object and
* add to the set of inhabitants of the city
*
* #param name
* #param datebirth
* #param maritalStatus
* #
*/
public void Add(String name,String datebirth,String maritalStatus) {
}
/**
* Return all inhabitants objects of the city
* #return
*/
static Set<Inhabitants> ReturnAll(){
return inhabitants;
}
/**
* Return city name
* #return
*/
static Set<Inhabitants> ReturnCityName(){
return inhabitants;
}
/**
* #return the name
*/
public String getName() {
return name;
}
/**
* #param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* #return the inhabitants
*/
public Set<Inhabitants> getInhabitants() {
return inhabitants;
}
/**
* #param inhabitants the inhabitants to set
*/
public void setInhabitants(Set<Inhabitants> inhabitants) {
this.inhabitants = inhabitants;
}
}
package main;
/**
* #version 0.1
*/
public class Inhabitants {
private String name;
private String datebirth;
private Boolean maritalStatus;
/**
* standard constructor
*/
public Inhabitants() {
}
/**
* #return the name
*/
public String getName() {
return name;
}
/**
* #param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* #return the datebirth
*/
public String getDatebirth() {
return datebirth;
}
/**
* #param datebirth the datebirth to set
*/
public void setDatebirth(String datebirth) {
this.datebirth = datebirth;
}
/**
* #return the maritalStatus
*/
public Boolean getMaritalStatus() {
return maritalStatus;
}
/**
* #param maritalStatus the maritalStatus to set
*/
public void setMaritalStatus(Boolean maritalStatus) {
this.maritalStatus = maritalStatus;
}
}

It sounds like a simple problem. You didn't need so much code:
package collections;
/**
* Person

* #since 6/20/2015 5:06 PM
*/
public class Person {
private final String name;
public Person(String name) {
if (name == null || name.trim().length() == 0) throw new IllegalArgumentException("name cannot be blank or null");
this.name = name;
}
public String getName() {
return name;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Person person = (Person) o;
return name.equals(person.name);
}
#Override
public int hashCode() {
return name.hashCode();
}
#Override
public String toString() {
final StringBuilder sb = new StringBuilder("Person{");
sb.append("name='").append(name).append('\'');
sb.append('}');
return sb.toString();
}
}
package collections;
