试图设计一个小型仪表板 - 我已经在2个mysql表中准备好了数据。我甚至有DAO和控制器工作正常。我想在一个JSP显示这些表...我的doGet（）看起来是这样的 -在一个jsp中显示多个mysql表
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String forward = "";
String action = request.getParameter("action");
forward = LIST_CASEDETAIL;
request.setAttribute("casedetails", dao.getDailyBoard());
request.setAttribute("caseweekly", dao.getWeeklyBoard());
RequestDispatcher view = request.getRequestDispatcher(forward);
view.forward(request, response);
}
问题没有1 - 这是允许的？ 问题2 - 如果是 - 它不工作。我的jsp在DailyBoard上显示。我需要明白我在这里做错了什么。非常感谢您的帮助。以下是从控制器，DAO & JSP代码
控制器

//private static String INSERT_OR_EDIT = "/ctsCaseDetailRegistration.jsp";
private static String LIST_CASEDETAIL = "/DailyBoard.jsp";
private CaseDairyDAO dao;
private ClientDAO clientDAO;
public DashBoardController() {
super();
dao = new CaseDairyDAO();
clientDAO = new ClientDAO();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
