在Servlet（EJB3，Jboss）上将字符串解析为Date

Question

First of all, please forgive my poor english. I want to search like SendDate on my feedback form, but it don't work, it said it can't parse string to date. Here is my code: 1.Session bean:

public Group3KSC.Feedback[] searchLikeSendDateFeedback(Date senddate) {
        try {
            Query query = em.createQuery("SELECT f FROM Feedback f WHERE f.sendDate LIKE :sendDate");
            query.setParameter("sendDate", "%" + senddate + "%");
            List list = query.getResultList();
            Feedback[] result = new Feedback[list.size()];
            list.toArray(result);
            return result;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

Search form:

 <form action="../AdminSearchSendDateServlet" method="post">
            <div> Search <input type="text" name="dbSearch" class="text-input datepicker"/>
                <p class="button">
                    <input type="submit" value="Search" name ="action"/>
                </p>
            </div>
        </form>

AdminSearchSendDateServlet (The Problem is here, when I declare searchsenddate)

HttpSession session = request.getSession();
        String action = request.getParameter("action");
        Context ctx = new InitialContext();
        AdminSessionBeanLocal local = (AdminSessionBeanLocal) ctx.lookup("AdminSessionBeanLocalJNDI");
        if (action.equals("Search")) {

            SimpleDateFormat fBirth = new SimpleDateFormat("MM/dd/yyyy");
            Date searchsenddate = fBirth.parse(request.getParameter("dbSearch").trim());
            Feedback[] u = local.searchLikeSendDateFeedback(searchsenddate);
            session.setAttribute("Username", u);
            response.sendRedirect("Admin/FeedbackList.jsp");
        }

ex: this record in database is:2014-05-25 00:00:00.000, when I search it in search form with date picker, it will input 05/25/2014, and when I'm click search button, it show those error

java.lang.ClassCastException: java.lang.String cannot be cast to java.util.Date

Thanks for your help

Answer 1

The 'sendDate' on DB is a Date columns? Have you tried pass the 'senddate' param as a date object instead of a string?

I hope it help.
