Spring 4 MVC based project with xml based configuration, want to use Jackson binding to return Json for some of the controller mappings (and it's going to Google App Engine). Did a lot of investigating, many different solution but they doing, each one, a bit different approach then the one we have. No yet working solution.

web.xml file:

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

    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring-config/application-context.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

Spring application-context.xml:

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

        <context:component-scan base-package="com.wixpress.automation"/>

        <bean id="viewResolver"
              class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix">
                <value>/WEB-INF/pages/</value>
            </property>
            <property name="suffix">
                <value>.jsp</value>
            </property>
        </bean>     
    </beans>

My example controller is pretty slim:

@Controller 
@RequestMapping("/api/")
public class Controller {

   @RequestMapping(value = "/name", method = RequestMethod.GET)
    @ResponseBody
    public Name nameexample(WebRequest request, Model model) {
        final Name name = new Name("name", "class", "package");
        return name;
    }
}

The class Name is a simple POJO with getters/setters, implements Serializable.

pom.xml got all the Jackson dependencies: jackson-databind, jackson-core, jackson-annotations, version 2.6.0. Spring used: 4.2.0.RELEASE

The error I receive when trying to GET the url: org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation

You could try using @RestController instead of @Controller.

    If I understand correctly, it's the same as using ResponseBody + Controller together, the same as I have. – Johnny Aug 27 '15 at 18:20
