来自servlet页面的输出值不会在JTable - Java GUI的行中更新

Question

来自Servlet页面的输出值正确，但这些值不会更新到Java JTable的行中。 行计数在JTable中递增但在Java GUI中没有刷新（显示）。

将数据添加到表格的行 - ＆gt;

public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws IOException, ServletException 
        {
    response.setContentType("text/html; charset=UTF-8");
    PrintWriter out = response.getWriter();
    try{
        //*****************slno***************************/
        String slno = request.getParameter("slno");
        a = slno;
        System.out.println("Source id--->:  "+demo123.a);
        out.println("<p>slno: " + slno + "</p>");
        //*****************lattitude***************************/
        String lattitude = request.getParameter("lattitude");
        b = lattitude;
        System.out.println("lattitude--->:  "+demo123.b);
        out.println("<p>lattitude: " + lattitude + "</p>");
        //*****************longitude***************************/
        String longitude = request.getParameter("longitude");
        c = longitude;
        System.out.println("longitude--->:  "+ demo123.c);
        out.println("<p>longitude: " + longitude + "</p>");

    ServerGUI.rows=ServerGUI.table.getRowCount();
        System.out.println("row count"+ServerGUI.table.getRowCount());
        ServerGUI.Tmodel.addRow(new Object[]{a,b,c});
        System.out.println( "Row count :" + ((DefaultTableModel)ServerGUI.table.getModel()).getRowCount());
        ServerGUI.table.repaint();
    } catch (Exception e) {}
}

Java GUI程序中的GUI JTable方法 - ＆gt;

table = new JTable();
    Tmodel = new DefaultTableModel(0,0);
    String header[] = new String[]{"SOURCE ID", "LATTITUDE", "LONGITUDE"};
    Tmodel.setColumnIdentifiers(header);
    table.setModel(Tmodel);
