Try Sun's JDBC site (java.sun.com/products/jdbc ) and search for it there
Try Hans bergsten site (thejspbook.com) and download
source example. I think there is CachedRowSet implementation there.

Subject: Re: Paging through result sets
I have looked at the info at the link you gave and the technique they show
is to use a cached rowset that reads all the data in from a given query (I
described this in option 2 of my original posting). They state that the
cached rowset is "not suitable for very large data sets". Ie. all the data
is read in from the query.
My original question still stands: what other techniques have you used to
implement paging strategies?
By the way, I cannot find the CachedRowset object anywhere in the java.sql
nor javax.sql packages - where is it?
