Not unless you would like to try posting non-private parts of your action class for list members to review.
In advance: thanks for all the work you put in some 'newbie'-problems! I've checked the "success"-issue, but this was'nt the problem.
Here are the java-files
********************** * EvaluatiePreAction * **********************
public final class EvaluatiePreAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
servlet.log("Does he get here?"); //==>The output never gives this!!
HttpSession session = request.getSession();
LogonForm logon = (LogonForm) session.getAttribute(Constants.USER_KEY);
if (logon == null) return (mapping.findForward("logon")); EvaluatieForm evaluatieForm = readEvaluatie(logon.getUsername()); EvaluatieForm evform = (EvaluatieForm) form; try { PropertyUtils.copyProperties(evform, evaluatieForm); } catch (InvocationTargetException e) { Throwable t = e.getTargetException(); if (t == null) t = e; throw new ServletException("RegistrationForm.populate", t); } catch (Throwable t) { throw new ServletException("RegistrationForm.populate", t); } return (mapping.findForward("success")); }
/** * @param username * @return */ private EvaluatieForm readEvaluatie(String username) { EvaluatieForm form = null; try { FileInputStream fis = new FileInputStream(username + ".txt"); ObjectInputStream ois = new ObjectInputStream(fis); form = (EvaluatieForm) ois.readObject(); ois.close(); } catch (Exception e) { } if (form == null) form = new EvaluatieForm(); return form; } }
