public void doView(RenderRequest req, RenderResponse rep)
| {
| rep.setContentType("text/html");
| String titre = (String) req.getParameter("titreformation");
| if (title !=null)
| {
| HttpServletRequest request = null;
| HttpServletResponse reponse = null;
| request.setAttribute("title", title);
| try {
| RequestDispatcher d = (RequestDispatcher)
getPortletContext().getRequestDispatcher(
| "/MyServlet");
| d.include(request, reponse);
| } catch (ServletException se) {
| System.out.print se);
| }
|
| }
but i have the following error:
