Answer 1

I got the answer

public void doGet(HttpServletRequest req, HttpServletResponse res) 
    throws IOException, ServletException
{

    List<HomePageServicesDescription> data = HomePageServicesDescriptionDB.showHomePageServicesDescription();
    req.getSession().setAttribute("description", data);

    res.sendRedirect("index.jsp");

}

And in index.jsp

List<HomePageServicesDescription> data= (List<HomePageServicesDescription>) session.getAttribute("description");

Its perfectly work

Answer 2

You should be doing HttpServletResponse.sendRedirect() instead of RequestDisaptcher.forward(). Any parameters you want to send can be sent as Query Parameters.

public void doGet(HttpServletRequest req, HttpServletResponse res) 
        throws IOException, ServletException
{

   List<HomePageServicesDescription> data =
             HomePageServicesDescriptionDB.showHomePageServicesDescription();
    req.setAttribute("description", data);

    res.sendRedirect("index.jsp?description="+data);

 }
