Sharing a bean information through jsp pages

Question

Morning,
I want to use a java bean in two jsp pages, so is it possible to share it (to set its properties in the 1st page and retrieve them in the 2nd)?
If not, what should I do? Could I use forward and set param?
Here is my 1st jsp
==================
<%@page language="java" %>
<jsp:useBean id="doctorConn" scope="session" class="beans.DoctorBean" >
     <jsp:setProperty name="doctorConn" property="*" />
</jsp:useBean>
<%
if(doctorConn.getUserId().equals("") ||doctorConn.getPassword().equals(""))
     response.sendRedirect("notAuthorised.jsp");
System.out.println("user id : " + doctorConn.getUserId()+ " password : " +doctorConn.getPassword());
if(doctorConn.isAuthorised(doctorConn.getUserId(), doctorConn.getPassword())) {
%>
     <jsp:forward page="doctorApp.jsp" />
<%
else response.sendRedirect("notAuthorised.jsp");
%>
==================
my second
=================
<%@page language="java" %>
<%@page import ="java.sql.*" %>
<%@page import ="java.lang.Exception"%>
<jsp:useBean id="doctorConn" scope="session" class="beans.DoctorBean" />
<jsp:useBean id="appointment" scope="session" class="beans.Appointment" >
     <jsp:setProperty name="appointment" property="*" />
</jsp:useBean>
...etc
===========================
I am using Tomcat 4 and in the 2nd page I am getting an error about doctorConn
Thank you,

Yes ofcorse. You can do it in many ways.
Firstly, declare properties of your bean as static that you want to share between pages and create new instance of bean on each page.
Secondly you can store the same instance of the bean in you session. On th other page, you can retrive same instance of the bean whenever needed.
Otherwise, you can create a gateway class that maitain static reference of you bean class.
