I'm sorry, my reply should have been directed to Chris, not Leon. My apologies, Leon.

This said, why don't you take a look at CachedRowSet? http://java.sun.com/j2se/1.5.0/docs/api/javax/sql/rowset/CachedRowSet.html http://java.sun.com/developer/Books/JDBCTutorial/chapter5.html I believe this could be somewhat similar to what you are looking for. HTH, Freddy. -----Mensaje original----- De: CRANFORD, CHRIS [mailto:[EMAIL PROTECTED] Enviado el: lunes, 14 de junio de 2004 13:45 Para: 'Struts Users Mailing List' Asunto: RE: Caching data from resultset This will work for the "paging" aspect, but I'm more concerned with ways to cache the "resultset" itself in the session to avoid repeative database calls on each page request. -----Original Message----- From: Rosenberg, Leon [mailto:[EMAIL PROTECTED] Sent: Monday, June 14, 2004 6:21 AM To: Struts Users Mailing List Subject: AW: Caching data from resultset Take a look at the pager taglib. http://jsptags.com/tags/navigation/pager/pager-taglib-2.0.html regards Leon > -----Ursprüngliche Nachricht----- > Von: CRANFORD, CHRIS [mailto:[EMAIL PROTECTED] > Gesendet: Montag, 14.
