                assoicatesDAO = new AssociatesDAO();
                boolean success = assoicatesDAO.leaveBalance(leave);
                if (success) {

                }
                request.setAttribute("responseMessage", msg);
                dispatcher = request.getRequestDispatcher("/jsp/success.jsp");
                dispatcher.forward(request, response);

您需要使用 java.util.Date 作为 SimpleDateFormat 处理 java.util.Date 而不 java.sql.Date.
