SpringMVC how to return a .doc file (from a jsp page)?

I'm trying to map a request for a "fake" MSWord file: the file is an html page actually, with a .doc extension to force the user to download it and open it with MS Word.

The source file /app/report.jsp is populated and shown as an HTML page if the mapped URL does not contains a .doc extension, but if I add the extension all the <jsp:include /> in the jsp file stop working, and at the same time the file is still rendered as a html document.

How can I force the user to download the file as a Word document?

Here is the method mapping the URL, from my controller:

@RequestMapping(value="/report.doc", produces = "application/msword")
    public ModelAndView reportProducer(HttpServletRequest request, HttpServletResponse response) {
        ModelAndView mav = new ModelAndView();
        mav.addObject("something", false);
        mav.setViewName("/app/report");
        response.setContentType("application/msword"); // probably unnecessary?
        return mav;
    }

here is the web.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:mvc="http://www.springframework.org/schema/mvc"
     xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
     id="WebApp_ID" version="3.1">

    <param-value>

    </param-value>
</context-param>

    <location>/WEB-INF/classes/jsp/app/errorPage.jsp</location>
</error-page>

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>/static/*</url-pattern>
</servlet-mapping>

</servlet>

<servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

</web-app>

and here is my applicationContext.xml file:

<?xml version="1.0" encoding="UTF-8"?>

   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

[... datasources, beans omitted ...]

<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/classes/jsp/"/>
    <property name="suffix" value=".jsp"/>
</bean>

</beans>

The issue with the incomplete parsing of the page (not including *.jspf parts) is related to a change I did while trying to solve the issue. I removed the following code from web.xml. When restored, everything worked as expected:

<servlet-mapping>
    <servlet-name>jsp</servlet-name>
    <url-pattern>*.jspf</url-pattern>
    <url-pattern>*.jsp</url-pattern>
</servlet-mapping>
