This tutorial show you how to use Jersey client APIs to create a RESTful Java client to perform “GET” and “POST” requests to REST service that created in this “Jersey + Json” example.
1. Jersey Client Dependency
To use Jersey client APIs, declares “jersey-client.jar” in your pom.xml file.
File : pom.xml
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-client</artifactId>
<version>1.8</version>
</dependency>
2. GET Request
Review last REST service.
@Path("/json/metallica")
public class JSONService {
@GET
@Path("/get")
@Produces(MediaType.APPLICATION_JSON)
public Track getTrackInJSON() {
Track track = new Track();
track.setTitle("Enter Sandman");
track.setSinger("Metallica");
return track;
}
//...
Jersey client to send a “GET” request and print out the returned json data.
package com.mkyong.client;
import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
public class JerseyClientGet {
public static void main(String[] args) {
try {
Client client = Client.create();
WebResource webResource = client
.resource("http://localhost:8080/RESTfulExample/rest/json/metallica/get");
ClientResponse response = webResource.accept("application/json")
.get(ClientResponse.class);
if (response.getStatus() != 200) {
throw new RuntimeException("Failed : HTTP error code : "
+ response.getStatus());
}
String output = response.getEntity(String.class);
System.out.println("Output from Server .... \n");
System.out.println(output);
} catch (Exception e) {
e.printStackTrace();
}
}
}
Output…
Output from Server ....
{"singer":"Metallica","title":"Enter Sandman"}
3. POST Request
Review last REST service.
@Path("/json/metallica")
public class JSONService {
@POST
@Path("/post")
@Consumes(MediaType.APPLICATION_JSON)
public Response createTrackInJSON(Track track) {
String result = "Track saved : " + track;
return Response.status(201).entity(result).build();
}
//...
Jersey client to send a “POST” request, with json data and print out the returned output.
package com.mkyong.client;
import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
public class JerseyClientPost {
public static void main(String[] args) {
try {
Client client = Client.create();
WebResource webResource = client
.resource("http://localhost:8080/RESTfulExample/rest/json/metallica/post");
String input = "{\"singer\":\"Metallica\",\"title\":\"Fade To Black\"}";
ClientResponse response = webResource.type("application/json")
.post(ClientResponse.class, input);
if (response.getStatus() != 201) {
throw new RuntimeException("Failed : HTTP error code : "
+ response.getStatus());
}
System.out.println("Output from Server .... \n");
String output = response.getEntity(String.class);
System.out.println(output);
} catch (Exception e) {
e.printStackTrace();
}
}
}
Output…
Output from Server ....
Track saved : Track [title=Fade To Black, singer=Metallica]

I am getting response from rest service and able to view as,
log.debug(“rest service response” + response.getEntity(String.class));
but when I capture the response in String Variable,
String output = response.getEntity(String.class);
System.out.println(“the output is: ” + output);
Output variable is having null value. Using jersey-client-1.19.4.jar
String input = “{\”singer\”:\”Metallica\”,\”title\”:\”Fade To Black\”}”;
ClientResponse response = webResource.type(“application/json”)
.post(ClientResponse.class, input);
Here You stored a simple data in String input. And pass that simple data(“String input”) as a POST request to the server.
My Question is :— 1) first, I store my xml data in a XML file .
2) I want to pass that xml data trough my XML file to the server as a POST request.
I tried below given code but its not woking
ClientResponse response = webResource.type(“MediaType.APPLICATION_XML”).entity(new File(“C:\\MyXml.xml”)
.post(ClientResponse.class);
So how can i read my xml data from my XML file in jersey client.? Ans transfer that xml data to server as a POST request to getting a correct response from server…?
can you give me the solution..?
how to set connection timeout on Web Application Server? I tried w”client.setConnectTimeout(0); and client.setConnectTimeout(600000);” which did not work. Webservice I hit takes more than 10 mins but the caller application connection timesout in 5 mins. Can someone help?
how to use Restful with struts 1.3
Thanks so much, let me show a better way to convert object to json in post using JACKSON:
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.ObjectWriter;
ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
String json = ow.writeValueAsString(objectInput);
Hugs!
String input = “{\”singer\”:\”Metallica\”,\”title\”:\”Fade To Black\”}”;
In this line we are hardcoding stuff.
But how to put dynamic content. I tried with “{\”+xyz+”\” which doesnt work.. can any1 help. Thanks in advance

I this above exception how could i add timeOut to server
Really a nice example to understand the get and post difference in client and server . Thank u so much .
can you please move to the latest version of Jersey 2.X. The examples are good, but 2.X have entirely different set of APIs.
How do I add basic authorization to a header? I tried this but it returns error 500:
Client client = Client.create();

values.add(“max”, “2”);
values.add(“table”, “abc”);

Hi, Just wondering how to send a object to a get request?. I need to send a list of many filter parameters which the user selects from UI and get the data back in Response. I can now retrieve data by passing the object in post request but this is wrong way of doing things as what the code actually does is a GET to the server which will retrieve data passing in the list.
The tutorial may be simple but its defenitely wrong. How can you say it is RESTful when you use something like @Path(“/post”). This is clearly RPC-Hybrid. You still thinking in methods not in resources.
Suggestion: @Path(“/album”).
Please do not post stuff randomly on your blog. (not the first time)
can you provide code which works for HTTPS url, ie for SSL connection.
Thank you! Great and simple tutorial
when i try to call post method it gives the error java.lang.RuntimeException: Failed : HTTP error code : 500.
Get method is properly works.
Thanks for the wonderful tutorial, Can we have https example like same
Hi Mkyong,
how do I assign the data received from service to a data structure on client side, e.g., XML and JSON data into a List of entity class? Will you please give some sample code?
Thanks in advance.
Thank you for your wonderful tutorial.
in POST Request, the status check should be for 200 , 201 was not working for me.
if (response.getStatus() != 201) {

}
should be
if (response.getStatus() != 200) {

If running on eclipse , make sure that your project is loaded on the server and the server is turned on .
I have tried alot…followed all the steps given but my hello world rest api is not running and giving an error Http status 404.
dont know whats wrong in it.
any help or suggestion is appreciated.
Thanks in advance.
Your articles are very simple and extremely helpful.
I thin you need to make slight change in the pom.xml as it fails if we run as it is.
The version of jersey-server needs to be 1.18.
com.sun.jersey
jersey-server
1.15
That would mean changes to the .classpath file of the project
why metallica? 🙂
This tutuorial was excellent and simple. It would be handy if you showed how to add arguments to the GET example. I tested by building my arguments into the webresource statement but I think there is a way to create queryParams before calling the webresource. Having trouble figuring this out at the moment.
Hi Thanks for the above example , I is working for me as expected could you please share how to display that JSON in jsp page
Hi,
Excellent tutorial and I got great help from it. Just a small note from my side. I did everthing as you said(well almost) but still got the following from message from my server
“Saved in Serverorg.ird.rest.model.Form@fb6763” when it should have returned JSON string. I removed the ‘result’ String object and directly added the object of the Class I recieved
return Response.status(201).entity(result).build();
to
return Response.status(201).entity(form).build();
to get:
{“formName”:”Follow-up”,”description”:”This is sent from client”}
which resulted in the expected JSON string being returned from server. Don’t know why concatenating a string message with the object cause this behaviour.
How do i pass a list in a json through using the above client.Sample Json should look like this:
{
“age”:100,
“name”:”mkyong.com”,
“messages”:[“msg 1″,”msg 2″,”msg 3”]
}
import org.codehaus.jettison.json.JSONObject
…
Map input = new HashMap();
input.put(“age”, “100”);
input.put(“name”, “mkyong.com”);
//not too sure about a list in a map, but try it out using same principle
JSONObject jsonList = new JSONObject(input);
ClientResponse response = webResource.type(“application/json”)
.post(ClientResponse.class, jsonList);
Hi,
How can I create a POST call by using the POSTMAN or FIDDLER tools?
Thanks, your tutorials have helped me many times. I’m looking around for some guidance and can’t seem to find anything covering my question.
I have a rest (Wink) service that @produces(“application/zip”), via below code. This works fine from the browser but I am writing a Wink Rest client to get the file and I would like to get the file from the Response.getEntity() so I can save it to disk and evaluate it, test it, etc. Maybe what I need is a FileProvider but I’m not sure if that’s the right direction.
I’d appreciate any guidance you could give me. Thanks!
ResponseBuilder responseBuilder = null; javax.ws.rs.core.Response response = null; InputStream in = null; try { in = new FileInputStream( createZipFile( filesToZip ) ); responseBuilder = javax.ws.rs.core.Response.ok(in, MediaType.APPLICATION_OCTET_STREAM_TYPE); response = responseBuilder.header("content-disposition", "inline;filename="file.zip").build(); } catch( FileNotFoundException fnfe) { fnfe.printStackTrace(); } return response;How can I have the JSON recieved on client side converted to Track object.
In SOAP based services, you had tools that provide stub/skeleton classes to convert to java objects on client side. Is something similar possible here
Too many times have I looked and learned from at your posts and not thanked you for it.
So here I am for all those times -THANK YOU, THANK YOU, THANK YOU! 😉
You always manage to keep it simple and to-the-point, and its easy to understand at first glance.
Great work and keep it up man.
Cheers!
These JSON/Jersey/Spring articles have been extremely helpful for me. Thank you for putting them togheter. Very easy to read and with some very good examples which I have shamelessy borrowed. 😛
This example is not working in Amazon’s Elastic Beanstalk
I could able to get it worked in localhost.
Any idea how I can see logs or proceed further?
I have done same thing but at the time getting values in String i got the following error please help me..
{“error”:{“code”:400,”message”:”Unable to complete operation.”,”details”:[“Invalid Token”]}}
thansk for this simple example. which helped me a lot.
If I just want to post a JSONObject (org.json.JSONObject or net.sf.json.JSONObject), what I should do?
why get and post are used as part of the url, it seems to me like REST url smell.
They don’t have to be used as a part of the url.
I have spent nearly 20 hours to get “JSONP” to work with Jersey to overcome the cross-domain issue.
Passing on…
Here is the JavaScript client side:
$.getJSON("http://localhost:8080/rest/json/metallica/get?callback=?", {}, function(data) { $("#status2").html( "<h2>" + data.singer + " " + data.title + "<h2>"); } );Here is the Java Server side
The trick is to match the callback parameter name (callback in this case) and to return a JSONWithPadding Object
The server side should be improved to return a collection instead of a simple Track object
package com.pacsman.jersey; import javax.ws.rs.Consumes; import javax.ws.rs.DefaultValue; import javax.ws.rs.GET; import javax.ws.rs.POST; import javax.ws.rs.Path; import javax.ws.rs.Produces; import javax.ws.rs.QueryParam; import javax.ws.rs.core.MediaType; import javax.ws.rs.core.Response; import com.mkyong.Track; import com.sun.jersey.api.json.JSONWithPadding; @Path("/json/metallica") public class JSONService { @GET @Path("/get") @Produces("application/x-javascript") public JSONWithPadding getTrackInJSON( @QueryParam("callback") @DefaultValue("CBParamIsMissing") String jsoncallback) { Track track = new Track(); track.setTitle("Enter Sandman"); track.setSinger("Metallica3"); return new JSONWithPadding(track, jsoncallback); } }Thanks a log for this tutorial.
hi thx for the sample this is a good example for basic understanding..
there is a small problem in sample we need to add @XmlRootElement in Track.call to make this work
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class Track {
No you dont unless you want to use jaxb
for example a’ve method in service like this
@POST
@Path(“/login”)
@Consumes(MediaType.APPLICATION_JSON)
public Response checkUser(String username, String password) {
………………….
}
How can i send multiple parameter from client. Thank you..
Thanks a lot for such easy and complete tutorial.
Simplicity makes it easy to understand.
Thanks for this great tutorial. Very much appreciated.

Hi Mykong,
Thanks for this useful website
But when i run this main class as a JAVA application, I m getting only the below o/p
from the
input is:{“singer”:”Metallica”,”title”:”Fade To Black”}
The response is: 415
Output from Server ….
I mean its not hitting my webservice JSONService and doesn’t give me the o/p
Track saved : Track [title=Fade To Black, singer=Metallica]
really a simple and great resource.
How’ve fixed?
How do you fix that?
Hi All,
Use the below additional dependency for the jersey-json.This will fix the issue.
