Has anyone had success with or have suggestions on  the following?

Use a statefull session bean to handle queries from a client (servlet).  The
statefull session bean will create and hold on to the resultset on behalf of
the client.  The client controls the display of "result pages" to the user
and calls methods on the statefull session bean to move through the
resultset.  The results are passed back to the client as a collection of
"state" objects.  The servlet will store a handle to the session bean in the
session.

Concerns:
Is this the proper design?
How long is the statefull session bean tied to the client?
Passivate/Activate - will the resultset be serialized/deserialized properly?
Can it handle large result sets? 20,000+ rows?

Thanks in advance,
Chris
