This is the "pattern" that is afaik the best way of handling Multipart requests

Action request from view layer goes to this method:

@ActionMapping(params = "javax.portlet.action=sample")
public void response(MultipartActionRequest request, ActionResponse response) {
    response.setRenderParameter("javax.portlet.action", "success");
    List<MultipartFile> fileList = request.getFiles("file");
}

render phase follows :

@RequestMapping(params = "javax.portlet.action=success")
public ModelAndView process(RenderRequest request, Model model) throws IOException {
    Map map = new HashMap();
    map.put("test", new Integer(1));
    return new ModelAndView("someView", map);
}

You create a "bean" view :

@Component("someView")
public class SomeView extends AbstractView {
    private Logger logger = Logger.getLogger(SomeView.class);

    @Override
    protected void renderMergedOutputModel(Map map, HttpServletRequest request, HttpServletResponse response)
            throws Exception {
    logger.info("Resolving ajax request view - " + map);
    JSONObject jsonObj = new JSONObject(map);
    logger.info("content Type = " + getContentType());
    response.setContentType("application/json");
    response.setCharacterEncoding("UTF-8");
    response.getWriter().write(jsonObj.toString());
    response.getWriter().flush();
    }
}

You add BeanNameViewResolver into your servlet/portlet context:

<bean class="org.springframework.web.servlet.view.BeanNameViewResolver" p:order="1" />
