Glenn,
I've put it on my website temporarily:
http://home1.gte.net/pfeiffer/Download.html
There is no documentation with it, but essentially what I have done is
replaced ResultSet with RowSet. The RowSetTag has a couple extra attributes
to tell it where to pull the populated RowSet object from.
Note that is does require the early access RowSet implementation from Sun:
http://developer.java.sun.com/developer/earlyAccess/crs/
Let me know if you have questions on it,
Bill Pfeiffer
