The web site would have been
http://reactorframework.org/, but Doug took it back, now it just shows Alagad inc. I don't mean to upset anyone, so I'll be very gentle. Reactor is not a very active project anymore. I liked it, but it always had some flaws that were never fully solved. This list has been incredibly quiet for a long time now. Other than that, if you have a copy of Reactor, it's good software that works.
The way to go now and into the future is probably ORM baked in with your CF server (Adobe CF 9+, Railo 4+ i think). If those aren't options for you then your server maintenance is falling too far behind.
