    WebApp Development

    Ricardo Viegas Newbie

      Im trying to develop a web aplication based on the webapp example but without the JSF and Im using the Bean classes as normal classes and not as beans.

      Im geting the tasklist for a user but when I click on the link to the taks nothing happens, I'm redirecting the link to a Servelet tha calls the the HomeBean.selectTaskInstance(). In the webapp it seems thats the only thing its being done.

      Can anyone help me?

            and here goes the servlet

            private void processarAccao(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException
            
             {
            
            
            
             ServletContext context = getServletContext();
            
             HttpSession session = req.getSession(true);
            
            
            
             try
            
             {
            
             System.out.println("Servelet");
            
             System.out.println("acção " + req.getParameter("accao"));
            
             System.out.println("opcao " + req.getParameter("opcao"));
            
             if (req.getParameter("accao").equals("verAccao"))
            
             {
            
             String id = req.getParameter("opcao");
            
             HomeBean hb = new beans.HomeBean(session);
            
             List lista = hb.getTaskInstances("ernie");
            
             hb.selectTaskInstance(Long.valueOf(id));
            
             } else
            
             {
            
             System.out.println("Falhou");
            
             }
            
             } catch (Exception e)
            
             {
            
             System.out.println(e.getMessage());
            
             System.out.println("MP----------");
            
             System.out.println(e.getCause());
            
             System.out.println("MP----------");
            
             e.printStackTrace();
            
             }
            
             }


            It doesnt return any error, just goes to a blank page, I tried to reproduce the same thing thats in the example.

              What are the parameters you are getting in the request?
              Is it going into the "if" block?

              Did you try debugging?

                yes its going into the if and I had put some debug messages in the bean, its going tru evering, I think.
                The message

                DEBUG [TaskBean] initialized availableTransitions null
                it is send in the task bean .

                de console its basicly the same if I run my aplication and the webapp ,

                  I think that when I do the comand

                  hb.selectTaskInstance(Long.valueOf(id));

                  There sould be something that redirects the browser page into the next page, right?

                  at least I didnt find anything else in the webapp

                    In the default web app (jbpm default webapp which uses JSF) the redirection is done using the faces-config.xml.

                    Where are you doing your redirection? If everything is fine in the servlet, where do you tell the system that redirect to next page?

                    Thanks.

                      Hey newbie, change your name... it should be expert007 now, or maybe expert42 (you know, life, the universe....)
