There is some good reading available on the net for the problem stated below:-

http://forum.java.sun.com/thread.jspa?threadID=694137&messageID=4033625

http://java.sys-con.com/read/37125.htm

http://java.sun.com/developer/onlineTraining/JSPIntro/contents.html

The code posted below is from Tomcat's , webapps examples, that is available on downloading it.

session.setAttribute and session.getAttribute are the two functions used as setter and getter for information from one jsp page to the other, in a session.



Source Code for Session Example

import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class SessionExample extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();

HttpSession session = request.getSession(true);

// print session info

Date created = new Date(session.getCreationTime());
Date accessed = new Date(session.getLastAccessedTime());
out.println("ID " + session.getId());
out.println("Created: " + created);
out.println("Last Accessed: " + accessed);

// set session info if needed

String dataName = request.getParameter("dataName");
if (dataName != null && dataName.length() > 0) {
String dataValue = request.getParameter("dataValue");
session.setAttribute(dataName, dataValue);
}

// print session contents

Enumeration e = session.getAttributeNames();
while (e.hasMoreElements()) {
String name = (String)e.nextElement();
String value = session.getAttribute(name).toString();
out.println(name + " = " + value);
}
}
}

You can do this using request.getParameter().
have a look at Servlet examples (http://www.jsptube.com) it has examples which will help you.
