Thank you for sharing you experience.I experienced the same problem and it works for me using configuration as show below:

1. Spring MVC Version : 3.2.5.RELEASE
2. Apache-tomcat-6.0.24
3. JDK1.6
4. jackson-core-asl-1.9.10.jar
5. jackson-mapper-asl-1.9.10.jar

Spring MVC Config File:

<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager"/>
<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<!-- Turn off working out content type based on URL file extension, should fall back to looking at the Accept headers -->
    <property name="favorPathExtension" value="false" />
</bean>

Model class : Country.java

 private Integer countryId;
 private String name;
 //public setters and getters

Controller Method:

@RequestMapping(value = "/get_country_json",method = RequestMethod.GET)
@ResponseBody
public Country getCountry()

Deployment Descriptor(web.xml)

 <servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>       
</servlet>
<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>*.htm</url-pattern>
</servlet-mapping>

URL Requested to call controller method: /SpringCURDApp/get_country_json.htm

I hope this can help someone.

I had the same problem and I solved it by adding following dependency

<dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-mapper-asl</artifactId>
    <version>${jackson.version}</version>
</dependency>

Previously I'm doing it with following dependency

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>${com.jackson.core-version}</version>
</dependency>

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>${com.jackson.core-version}</version>
</dependency>

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>${com.jackson.core-version}</version>
</dependency>

In short I have replace com.fasterxml.jackson.core by org.codehaus.jackson
