Getting Edit or Help mode markup from the Flex portlet

I made changes in the How to make action or render request from the Adobe Flex so that it makes request to get the markup for Edit and Help mode from the Flex. These are the changes in the source code

public class SPRInFlexPortlet extends javax.portlet.GenericPortlet {
    public void doView(RenderRequest request, RenderResponse response) 
throws PortletException, IOException {
        // Set the MIME type for the render response
        response.setContentType(request.getResponseContentType());
        System.out.println("Entering SPRInFlexPortlet.doView()");
        if(request.getParameter("caller") == null){
            System.out.println("Request from portal, not flex");
            SPRUtil sprUtil = new SPRUtil();
         String editModeUrl = sprUtil.getPortletEditModeUrl(request, response);
            String helpModeUrl = sprUtil.getPortletHelpModeUrl(request, response);
            request.setAttribute("editModeUrl", editModeUrl);
            request.setAttribute("helpModeUrl", helpModeUrl); 
            getPortletContext().getRequestDispatcher("/sprinflex.jsp").include(request, response);
            return;
        }
        PrintWriter out = response.getWriter();
        out.println("Listing out parameters in the SPRFlexPortlet.doView()");
        Enumeration paramNames = request.getParameterNames();
        while(paramNames.hasMoreElements()){
            String paramName = paramNames.nextElement();
            System.out.println(paramName +" " + request.getParameter(paramName));
            out.println(paramName +" " + request.getParameter(paramName)+" ");
        }
        System.out.println("Got request for the first time");
    }
    public void processAction(ActionRequest request, ActionResponse response) 
throws PortletException, java.io.IOException {
        System.out.println("Entering SPRInFlexPortlet.processAction");
        Enumeration paramNames = request.getParameterNames();
        while(paramNames.hasMoreElements()){
            String paramName = paramNames.nextElement();
            System.out.println(paramName +" " + request.getParameter(paramName));
            response.setRenderParameter(paramName, request.getParameter(paramName));
        }
        response.setRenderParameter("requestType", "action");
        System.out.println("Exiting SPRInFlexPortlet.processAction");
    }
    protected void doEdit(RenderRequest request, RenderResponse response)
            throws PortletException, IOException {
        System.out.println("Entering SPRInFlexPortlet.doEdit");
        response.setContentType(request.getResponseContentType());
        response.getWriter().println("Returning response from SPRInFlexPortlet.doEdit()");
        System.out.println("Exiting SPRInFlexPortlet.doEdit");
    }
    protected void doHelp(RenderRequest request, RenderResponse response)

            throws PortletException, IOException {
        System.out.println("Entering SPRInFlexPortlet.doHelp");
        response.setContentType(request.getResponseContentType());
        response.getWriter().println("Returning response from SPRInFlexPortlet.doHelp()");
        System.out.println("Exiting SPRInFlexPortlet.doHelp");
    }
}
