406 Not Acceptable in Spring MVC application (OSGi, Virgo Web Server) using Jackson, Rome and JAXB2

I just started learning the Virgo Web Server. I'm trying to work with Jakcson JSON in Spring MVC application. At this stage I can not get a GET request serialized object. The server returns "406 Not Acceptable": ``` The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers (). ``` The same problem arises when using Rome and JAXB2. Here is the project configuration files and code: Fragment pom.xml: ``` <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>com.springsource.org.codehaus.jackson</artifactId> <version>1.0.0</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>com.springsource.org.codehaus.jackson.mapper</artifactId> <version>1.0.0</version> </dependency> ``` MANIFEST.MF ``` Manifest-Version: 1.0 Import-Bundle: com.springsource.org.apache.taglibs.standard;version="[ 1.1.2,1.3)",com.springsource.org.codehaus.jackson;version="[1.0.0,1.0 .0]",com.springsource.org.codehaus.jackson.mapper;version="[1.0.0,1.0 .0]" Bundle-Version: 2.3.0 Tool: Bundlor 1.0.0.RELEASE Bundle-Name: GreenPages Web Import-Library: org.springframework.spring;version="[3.0, 3.1)" Bundle-ManifestVersion: 2 Bundle-SymbolicName: greenpages.web Web-ContextPath: greenpages Import-Package: javax.servlet.jsp.jstl.core;version="[1.1.2,1.2.0)",ja vax.sql,org.apache.commons.dbcp,org.eclipse.virgo.web.dm;version="[2. 0.0, 3.0.0)",org.springframework.core.io;version="[3.0.0.RELEASE,3.1. 0)",org.springframework.stereotype;version="[3.0.0.RELEASE,3.1.0)",or g.springframework.ui;version="[3.0.0.RELEASE,3.1.0)",org.springframew ork.web.bind.annotation;version="[3.0.0.RELEASE,3.1.0)",org.springfra mework.web.servlet.mvc.annotation;version="[3.0.0.RELEASE,3.1.0)",org .springframework.web.servlet.view;version="[3.0.0.RELEASE,3.1.0)" ``` web.xml ``` <?xml version="1.0" encoding="ISO-8859-1"?> <web-app 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_2_5.xsd" version="2.5"> <welcome-file-list> <welcome-file>/WEB-INF/pages/index.jsp</welcome-file> </welcome-file-list> <!-- CONFIGURE A PARENT APPLICATION CONTEXT --> <context-param> <param-name>contextClass</param-name> <param-value>org.eclipse.virgo.web.dm.ServerOsgiBundleXmlWebApplicationContext</param-value> </context-param> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- DISPATCHER SERVLET CONFIG --> <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> </web-app> ``` dispatcher-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:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <context:component-scan base-package="greenpages.web"/> <!-- Configures the @Controller programming model --> <mvc:annotation-driven /> <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="prefix" value="/WEB-INF/pages/"/> <property name="suffix" value=".jsp"/> </bean> </beans> ``` GreenPagesController.java ``` package greenpages.web;
