Not able to evaluate Expression Language

Hi,

I have started developing some samples using EL and JSTL.

I am using Tomcat 6 and Eclipse Helios ,I have evaluated an Expression Language which is not coming properly.
Is there any external file needed to evaluate the Expression Language. For JSTL which jar is needed.

I am attaching all my source file for more clarity.

service method

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
Person p =new Person();
p.setName("Sumit");
request.setAttribute("person", p);
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/Result.jsp");
dispatcher.forward(request, response);
}

Result.jsp
