我正在尝试将数据获取到数据表

Question

我正在尝试使用ajax，但是ajax无法正常工作。所以我提到： https://datatables.net/manual/ajax。

一个数据对象，什么也没得到。

这是我的Javascript代码

$(document).ready(function(){
            var table = $('#myTable').DataTable({
                ajax: 'notUsed.ad',
                columns: [
                {"data":'memNum'},
                {"data":'memId'},
                {"data":'memName'},
                {"data":'memGender'},
                {"data":'memPhone'},
                {"data":'nationCode'},
                {"data":'memPoint'},
                {"data":'memType'},
                {"data":'memStatus'},
                {"data":'enrollDate'},
                {"data":'noShow'}
                ]
            });
});

和HTML标记：

<table id="myTable" class="table table-bordered display">
    <thead>
        <tr>
            <th>num</th>
            <th>id</th>
            <th>name</th>
            <th>gender</th>
            <th>phone</th>
            <th>nation</th>
            <th>point</th>
            <th>type</th>
            <th>status</th>
            <th>enroll_date</th>
            <th>noshow</th>
        </tr>
    </thead>
</table>

和servlet

public class TableMemSearch extends HttpServlet {
    private static final long serialVersionUID = 1L;
    public TableMemSearch() {
        super();
    }

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        ArrayList<Member> list = new AdminService().searchMember();

        JSONArray jArr = new JSONArray();
        JSONObject jobj = new JSONObject();

        for (Member m : list) {
            JSONObject jsonMember = new JSONObject();
            jsonMember.put("memNum", String.valueOf(m.getMemNum()));
            jsonMember.put("memId", String.valueOf(m.getMemNum()));
            jsonMember.put("memName", String.valueOf(m.getMemName()));
            jsonMember.put("memGender", String.valueOf(m.getMemGender()));
            jsonMember.put("memPhone", String.valueOf(m.getMemPhone()));
            jsonMember.put("nationCode", String.valueOf(m.getNationCode()));
            jsonMember.put("memPoint", String.valueOf(m.getMemPoint()));
            jsonMember.put("memType", String.valueOf(m.getMemType()));
            jsonMember.put("memStatus", String.valueOf(m.getMemStatus()));
            jsonMember.put("enrollDate",String.valueOf(m.getEnrollDate()) );
            jsonMember.put("noShow",String.valueOf( m.getNoShow()));
            jArr.add(jsonMember);
        }
        jobj.put("data", jArr);

        response.setContentType("application/json; charset=utf-8");
        response.getWriter().print(jobj);

它什么也不返回。

没有错误，没有结果。

我不知道该怎么办。这是结果的屏幕截图，并且在Eclipse中没有错误：
