JSP; Servlets;  html: How do I retreave a value from a session object into a JSP?

One of my servlets, Address.java binds a value to a session object:
       HttpSession session = request.getSession(true);
      session.setAttribute("location", lcn);

Then I have a JSP to display a table, but the value is not retrieved from the session object.

FOR EXAMPLE, the following does not work:
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@page session="true"%>

<html>
<body>
<center>
<table cellpadding=4 cellspacing=2 border=0>
 
<th bgcolor="#CCCCFF" colspan=3>
<font size=4>THE LOCATION</font>
<br>
<br>
</th>

<tr bgcolor="#c8d8f8">
<td valign=top>
<b>Location</b>
<br><br>
<% String location = (String) session.getAttribute("location"); %>

What am I missing in the above four lines to make them work?
I get no error message. The table displays but without the value of location. I'd appreciate your instruction.

HttpSession session = request.getSession(true);
     session.setAttribute("location", lcn);
System.err.println(lcn);  //test this whether u r getting right value here itself

I've discovered I had to add one line <%= location %> to have the following that works:

                     <tr bgcolor="#c8d8f8">
                     <td valign=top>
                     <b>Location</b>
                     <br><br>
                     <% String location = (String) session.getAttribute("location"); %>
                     <%= location %>
Thanks
