I want to send JSON from my controller. I have the following configuration.

**spring-servlet.xml :**

```
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
           http://www.springframework.org/schema/mvc
           http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <mvc:annotation-driven/>

    <mvc:resources mapping="/resources/**" location="/resources/"/>
    <context:component-scan base-package="com.castle.controllers"/>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

```

**.js :** 

```
function testAjax() {
    var data = {userName: "MyUsername", password:"Password"};
    $.ajax({
        url: 'ajax/test.htm',
        dataType : 'json',
        type : 'POST',
        contentType: "application/json",
        data: JSON.stringify(data),
        success: function(response){
            alert('Load was performed.');
        }
    });
}

```

**UserTest.java:**

```
public class UserTest {
    private String userName;
    private String password;

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

```

**TestAjaxController.java :** 

```
@Controller
@RequestMapping("/ajax")
public class TestAjaxController {

    @RequestMapping(method = RequestMethod.POST, value = "/test.htm")
    public @ResponseBody
    UserTest testAjaxRequest(@RequestBody UserTest user) {
        return user;
    }
}

```

**pom.xml :** 

```
    <dependency>
                <groupId>org.codehaus.jackson</groupId>
                <artifactId>jackson-mapper-asl</artifactId>
                <version>1.9.13</version>
            </dependency>
            <dependency>
                <groupId>org.codehaus.jackson</groupId>
                <artifactId>jackson-core-asl</artifactId>
                <version>1.9.13</version>
</dependency>

```

When i do this request, i get in my Controller JSON represented as UserTest object. But on return :

HTTP Status 406 - The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.

What i'm doing wrong? I know, there is a lot of questions about such cases, but i can't fix it for 2 days...

**UPDATE**
I Have found the solution!!
It's only need to return an Object. Not a User object or something. 
But 
`return Object;` 

```
 public @ResponseBody Object testAjaxRequest(@RequestBody UserTest user) {
        List<UserTest> list = new ArrayList<>();
        list.add(user);
        list.add(user);
        list.add(user);
        return list;

```
