Returning ResultSet to jsp from servlet

Question

Hi,
I am trying to return a ResultSet (generated in servlet) to a jsp page, but get a "java.lang.ClassCastException" error. Here is my description of what i'm doing....
I have a search screen (SearchInventory.jsp) that the user goes to to perform the search based on a few variables. When the search button is clicked, i go to a servlet (SearchInventory.java) which gets a ResultSet. In the servlet, i am storing the ResultSet into a bean object, and finally use the RequestDispatcher to redirect to the .jsp page. (and get the "java.lang.ClassCastException" error).
Here is the relevant code from all parts of the app:
SearchInventory.java:---------------------------------------------------------------------
SearchBean sbean=new SearchBean();
String QueryStr="select ProdName from products";
Statement stmt=conn.createStatement();
rs=stmt.executeQuery(QueryStr);
sbean.setSearchRS(rs);
req.getSession(true).setAttribute("s_resbean",sbean);
HttpSession session=req.getSession(true);
session.setAttribute("s_resbean",rs);
req.setAttribute("sbean",rs);
String url="/SearchInventory.jsp";
RequestDispatcher dispatcher=getServletContext().getRequestDispatcher(url);
dispatcher.forward(req,res);
SearchBean.java:
public class SearchBean extends HttpServlet{
private int searchFlag=0;
private static ResultSet searchRS;
     public void setSearchRS(ResultSet rs){
          this.searchRS=rs;
And finally, the .jsp page..SearchInventory.jsp:
<%@ page language="java" import="java.lang.*,java.sql.*,javax.sql.*,PopLists.PopInvLists,beans.SearchBean"%>
<jsp:useBean scope="session" id="s_resbean" class="beans.SearchBean" />
ResultSet search=(ResultSet)request.getAttribute("s_resbean");
If i don't cast it to type ResultSet, i get the following error, which leads me to believe that i should be casting it to a Result Set.
C:\Apache\tomcat_4.1.29\work\Standalone\localhost\DBTest\SearchInventory_jsp.java:75: incompatible types
found : java.lang.Object
required: java.sql.ResultSet
ResultSet search=request.getAttribute("s_resbean");
Please help...
Thanks in advance,
Aditya.

Yikes...i realized some of my many problems...i'm using setAttribute multiple times here...(shown by arrows at the end)
sbean.setSearchRS(rs);
req.getSession(true).setAttribute("s_resbean",sbean);//<--
HttpSession session=req.getSession(true);
session.setAttribute("s_resbean",rs);//<--
req.setAttribute("sbean",rs);//<--
I've tried using one at a time since, and it still doesn't work. How exactly should i be setting the attribute. I don't think any of the methods listed above are completely correct...cause it's never worked!:(
Is anything that i've done correct? (ie. bean/jsp). I'm really starting to doubt myself now. I've been reading up on this, and some people say that one shouldn't return a ResultSet to the jsp, but instead return an ArrayList. Is this correct? If so, how do i convert an ResultSet to an ArrayList?
