I'm trying to make a call to a web service with following code:
/*

import javax.xml.rpc.*;
import javax.xml.rpc.encoding.XMLType;
public class termine
{
public static void main(String[] args) throws Exception
{
String sentence = "Technical terms are important for knowledge mining, especially in the bio-medical area where vast amount of documents are available.";
String wsdlURL = "http://www.nactem.ac.uk/software/termine/webservice/termine.wsdl";
URL url = new URL(wsdlURL);

String portName = "termine_porttype";
String operationName = "analyze";
QName serviceQN = new QName(targetNamespace, serviceName);

call.setReturnType(XMLType.XSD_STRING);
System.out.println(call.invoke(inParams));
}
catch (Exception e) {e.printStackTrace();}
}
}
However, I receive the following error.

From reading about similar problems on the web I got the impression that I'm not using the right libraries. In my pom.xml I have the following dependencies provided:
<dependency>
<groupId>javax.xml</groupId>

<artifactId>xercesImpl</artifactId>
<version>2.11.0</version>

Could you please help me to resolve this problem?
Thanks!
Adding the following dependency to my pom.xml solved the problem (partially because other dependencies seem to be still missing).
<dependency>

I have tried several solutions found on internet but nothing seems to be working for this.
Can anybody please tell me what wrong I am doing in above code snippet?
I am able to partially fix the issue by creating the below wrapper class.
import java.util.Map;
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement
public class JaxrsMapWrapper<T,K> {
private Map<T,K> map;
public JaxrsMapWrapper(){
}
#Override
public String toString() {
return map .toString();
}
public void setMap(Map<T,K> map) {
this.map = map;
}
public Map<T,K> getMap() {
return map;
}
}
By using the above class below getservice returning the typeof Map is working absolutly fine.
#GET
#Path("/mapWarpperReceive")
#Produces({MediaType.APPLICATION_XML})
public JaxrsMapWrapper<String,String> getWarpperMapMsgStr()
{
System.out.println("Returning the MapMessage as String ");
Map<String,String> originalMap=new HashMap<String,String>(){{put("a","a");put("b","b");}};
JaxrsMapWrapper<String,String> jaxRsMapWrapper=new JaxrsMapWrapper<>();
jaxRsMapWrapper.setMap(originalMap);
return jaxRsMapWrapper;
}
But when I am trying to use the same class JaxrsMapWrapper with type of Map it is throwing Error 500 Internal server error while invoking through postman.
#GET
#Path("/customMap")
#Produces({MediaType.APPLICATION_XML})
public JaxrsMapWrapper<String,BookBo> getWarpperMapMsgWithCustomObject()
{
System.out.println("Returning the MapMessage as String and Custom Message ");
Map<String,BookBo> originalMap=new HashMap<>();
originalMap.put("a",new BookBo(1,"Jinesh"));
JaxrsMapWrapper<String,BookBo> jaxRsMapWrapper=new JaxrsMapWrapper();
jaxRsMapWrapper.setMap(originalMap);
return jaxRsMapWrapper;
}
Below is the code for the User defined Java Object BookBo.
#XmlRootElement
public class BookBo implements Serializable{
private Integer id;
private String name;
public BookBo() {
}
public BookBo(Integer id, String name) {
super();
this.id = id;
this.name = name;
}
//getters and setters of the field
}
What am I missing in the above code due to which while writing the Map in response is not working?
So I am trying to implement a simple Jersey Client that hits a public API to get movie times etc..
https://api.eventcinemas.co.nz/Api/Movies/GetMovies
I have gone through tutorials on how to do this and have implemented two methods that deserialzse the JSON response into:
A String
An Object (POJOs)
The issue is this: the JSON to String method is working correctly, printing the String to console gives me the expected result. However when trying to deserialize to my Java Objects I am always getting null.
I have tried a few simple things such as different dependency versions, different API calls etc but no luck. To save time I have used an online converter to take the JSON response and populate the necessary POJOs for deserialization, I have taken this to be correct.
Would someone be kind enough to point me in the right direction on why I am always getting null, I feel like its something small or silly that I have missed. Thanks in advance!
So starting with my pom.xml dependencies...

My Client is as follows:
MoviesClient:
package nz.co.brownbridge.application;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.MediaType;
public class MoviesClient {
protected MoviesResponse getMovieDetails() {
/*JSON to POJO*/
Client client = ClientBuilder.newClient();
WebTarget webTarget = client.target("https://api.eventcinemas.co.nz/Api/Movies/GetMovies");
MoviesResponse response = webTarget.request().accept(MediaType.APPLICATION_JSON_TYPE).get(MoviesResponse.class);
return response;
}
protected String getMovieDetailsString() {
/*JSON to String*/
Client client = ClientBuilder.newClient();
WebTarget webTarget = client.target("https://api.eventcinemas.co.nz/Api/Movies/GetMovies");
String response = webTarget.request().accept(MediaType.APPLICATION_JSON_TYPE).get(String.class);
return response;
}
}
and finally the main() class:
Application Class:
package nz.co.brownbridge.application;
public class Application {
public static void main(String[] args) throws InterruptedException {
MoviesClient moviesClient = new MoviesClient();
String stringResponse = moviesClient.getMovieDetailsString();
MoviesResponse pojoResponse = moviesClient.getMovieDetails();
System.out.println("Printing String Response...");
System.out.println();
System.out.println(stringResponse);
System.out.println();
System.out.println();
System.out.println("Printing POJO Response...");
System.out.println();
System.out.println(pojoResponse);
}
}
Would output the following:
Printing String Response...
//super long but correct string response goes here
Printing POJO Response...
ClassPojo [Data = null, Success = null]
Am trying to populate a DTO from a published RESTful URL (simple HTTP GET) by using Spring's RestTemplate HTTP Client.
This is the content of the published JSON that I am trying to consume:
[{"startDate":"2017-01-29","cost":"$50000.00","id":1112,"name":"Porsche"},{"startDate":"2017-03-06","cost":"$27000.00","id":38626,"name":"BMW"}]
My DTO:
class DTO {
private String startDate;
private String cost;
private String name;
// Getters and Setters
}
My Response Object:
public class Response {
private static final STRING = "http://www.sample.com/product";
public static List<Object> getCampaigns() {
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<Object[]> responseEntity = (ResponseEntity) restTemplate.getForEntity(URL, Object[].class);
Object[] objects = responseEntity.getBody();
MediaType contentType = responseEntity.getHeaders().getContentType();
HttpStatus statusCode = responseEntity.getStatusCode();
return Arrays.asList(objects);
}
public void static main (String args []) {
List<Object> dtos = getCampaigns();
for (Object dto : dtos) {
System.out.println(dto.toString());
}
}
}
Here's my pom.xml:

When I run the main() method inside Response, I get the following exception:
00:24:14.191 [main] DEBUG org.springframework.web.client.RestTemplate - GET request for "http://www.sample.com/product" resulted in 200 (OK)

What am I possibly doing wrong?
Try this
public class Response {
private static final String URL = "http://www.sample.com/product";
public static List<DTO> getCampaigns() {
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<DTO[]> responseEntity = restTemplate.getForEntity(URL, DTO[].class);
DTO[] objects = responseEntity.getBody();
MediaType contentType = responseEntity.getHeaders().getContentType();
HttpStatus statusCode = responseEntity.getStatusCode();
return Arrays.asList(objects);
}
public void static main (String args []) {
List<DTO> dtos = getCampaigns();
for (DTO dto : dtos) {
System.out.println(dto.toString());
}
}
}
use this jackson library instead
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>

I have RESTful service based on Jersey 1.18.1 and I want to show my API via Swagger.
Firstly I have to get JSON. I read this instruction: Swagger Core Jersey 1.X Project Setup 1.5. Swagger allows to set up a configuration different methods and I decided to use custom Application subclass. I did everything step by step but I can't get JSON which I have to use for swagger-ui.
What I did:
My custom Application
#ApplicationPath("api/v1")
public class DiscountsApp extends Application{
public DiscountsApp() {
BeanConfig beanConfig = new BeanConfig();
beanConfig.setVersion("1.0.2");
beanConfig.setSchemes(new String[]{"http"});
beanConfig.setHost("localhost:8002");
beanConfig.setBasePath("swaggerapi");
beanConfig.setResourcePackage("alexiuscrow.diploma.endpoints");
beanConfig.setScan(true);
}
#Override
public Set<Class<?>> getClasses() {
Set<Class<?>> resources = new HashSet();
resources.add(ShopsResources.class);
//...
resources.add(com.wordnik.swagger.jaxrs.listing.ApiListingResource.class);
resources.add(com.wordnik.swagger.jaxrs.listing.SwaggerSerializers.class);
return resources;
}
}
ShopsResources
#Path("/shops")
#Api(value="/shops", description="Shops")
public class ShopsResources {
#GET
#Produces(MediaType.APPLICATION_JSON)
#ApiOperation(value = "List shops", httpMethod = "GET",
notes = "List nearest or locality shops",
response = Shops.class, responseContainer = "List")
public String getShops(
#ApiParam( value = "Radius", required = false)
#QueryParam("radius") String radiusParam,
#ApiParam( value = "Latitude", required = true)
#QueryParam("lat") String latParam,
#ApiParam( value = "Longitude", required = true)
#QueryParam("lng") String lngParam) throws SQLException{
//The list of Shops objects is serialized to string
//using the custom GSON serializer and I know
//that there is the better method of the solution of this task.
}
}
}

After deploy application to Tomcat I tried to get http://localhost:8002/swaggerapi but I've got no result.
I didn't find the swagger.json in root of my application (/tomcat8/webapps/app).
What's wrong?
How can I get JSON with my API?
I did not correctly build the url.
Correct:
http://{host}:{port}/{context root of application}/{path from #ApplicationPath}/swagger.json
In my case: http://localhost:8080/app/api/v1/swagger.json
Thx to Ron.
adding a relative path worked for me (this is using .netcore 1.1)
app.UseSwaggerUI(s => {
s.RoutePrefix = "help";
s.SwaggerEndpoint("../swagger/v1/swagger.json", "MySite");
s.InjectStylesheet("../css/swagger.min.css");
});
