RE: Design Doubt
Create an action that takes in the start id and the quantity to scroll over, and your
query (total of 3 params). Read up on your DB specific SQL language for specifying a
start id and max rows to return (not applicable for this mailing list). Enstate
whatever kind of caching you want, but leave querying to request based only. That's
how most "big" sites do it.

Easiest way without too many details (lots of opinions on getting data from
database):
1. Put data into an ArrayList of Beans (forms, POJOs, whatever).
2. Use display tag library for display/sorting/paging -
