Not able to POST JSON data to Jersey Restful Web service

Question

I'm trying to send JSON data to my RESTful web service. Configuration is working fine for a simple GET type. Only the issue is for POST type.

My Angular code

var app = angular.module('myApp', []);
app.controller('MyController', function($scope,$http) {
$scope.pushDataToServer = function() {
    $http({
        method: 'POST',         
        url: 'rest/Board/autoSave',
        headers: {'Content-Type': 'application/json'},
        data:'{"firstName":"Syed", "lastName":"Chennai"}',
        }).success(function (data){
            $scope.status=data;
        }).error(function(data, status, headers, config) {
            alert("error");
       });      
    };
});

My Java code

@Path("/Board")
public class BoardAutoSaveService {

    @POST
    @Path("/autoSave")
    @Consumes({MediaType.APPLICATION_JSON})
    @Produces({MediaType.TEXT_PLAIN})
    public String  autoSave(Message msg) throws Exception{
        System.out.println("Calling Autosave.");
        System.out.println("First Name = "+msg.getFirstName());
        System.out.println("Last Name  = "+msg.getLastName());
        return null;        
    }
}

Message class

package com.intu;
import java.util.Date;
public class Message {

private String firstName;

private String lastName;

private int age;

private Date date;

private String text;



public String getFirstName() {
    return firstName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
}

public String getLastName() {
    return lastName;
}

public void setLastName(String lastName) {
    this.lastName = lastName;
}

public int getAge() {
    return age;
}

public void setAge(int age) {
    this.age = age;
}

public Date getDate() {
    return date;
}

public void setDate(Date date) {
    this.date = date;
}

public String getText() {
    return text;
}

public void setText(String text) {
    this.text = text;
}

}

Web.xml

      <?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

      <servlet-name>Jersey RESTful Application</servlet-name>
      <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>
   </web-app>

Am I missing anything?

The error is

SEVERE: A message body reader for Java class com.intu.Message, and Java type class com.intu.Message, and MIME media type application/json was not found.
The registered message body readers compatible with the MIME media type are:

did you try removing `single quotes` around data? you can send object as well not necessarily string only. — Sindhoo Oad, Feb 19 '16 at 05:20
try adding POJOMappingFeature in web.xml and annotate your Message class by @XmlRootElement — Saurabh, Feb 19 '16 at 05:34
@user3142222, but why? I'm not going to push XML data to my DB right? I'm just fetching the JSON data sent via Angular. — Syed, Feb 19 '16 at 05:36

You only have the default Jersey JSON providers, which require @XmlRootElement on your model class. You can see the available providers, one of which is the JSON**RootElement**Provider

com.sun.jersey.json.impl.provider.entity.JSONJAXBElementProvider$App
com.sun.jersey.json.impl.provider.entity.JSONRootElementProvider$App
com.sun.jersey.json.impl.provider.entity.JSONListElementProvider$App

This provider is used to (de)serialize classes annotated with @XmlRootElement.

If you have the following dependency

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-json</artifactId>
    <version>${jersey.version}</version>
</dependency>

then it should also pull in the Jackson provider, which doesn't require @XmlRootElement, but you still need to configure Jersey to use Jackson instead of its default provider. To configure it you need to add this to your web.xml Jersey servlet configuration, as seen here

<init-param>
    <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
    <param-value>true</param-value>
</init-param>

Or if you are not using a web.xml, add the following inside your ResourceConfig subclass constructor

public class AppConfig extends PackagesResourceConfig{

    public AppConfig() {
        getProperties().put(JSONConfiguration.FEATURE_POJO_MAPPING, true);
    }
}

Hi Peekskilet. I'm not using Maven project. What should I do? – Syed Feb 19 '16 at 05:50
Which JAR should I need to include? – Syed Feb 19 '16 at 05:51
You can look at the image from [this post](http://stackoverflow.com/a/31991892/2587435) – Paul Samsotha Feb 19 '16 at 05:55
Then you need to register the `JacksonJsonProvider`. You can just add this package (`com.fasterxml.jackson.jaxrs.json`) to the list of packages to scan, in your web.xml – Paul Samsotha Feb 19 '16 at 05:56
i.e. `com.dao,com.fasterxml.jackson.jaxrs.json` – Paul Samsotha Feb 19 '16 at 05:58
If you do it this way, you can ignore all that stuff about the `POJOMappingFeature`. It will not be required – Paul Samsotha Feb 19 '16 at 05:59
It worked when I included Jackson JAR's. Should I add this tag in web.xml too? – Syed Feb 19 '16 at 05:59
Not exactly sure what jars you added, so I am not sure how you got it working. But if it's working, I would say you don't need it. – Paul Samsotha Feb 19 '16 at 06:01
Cool. I added Jackson-core-asl-1.9.2, jackson-jaxrs, jackson-mapper-asl-1.9.2 & jackson-xc-1.9.2. – Syed Feb 19 '16 at 06:02
