In a quick search for display libraries I landed on the ValueList project. It really worth some exploration, especially with its spring configuration and direct resultset fetching for a better memory utilization (rather than in-memory lists in Displaytag)/
Through another search for ValueList discussions, I landed on a bigger find, DbForms. It looks like a solution that I have been discussing with some friend (A solution for delivering basic web apps through a simple GUI, aka RAD). I will be putting some time to playing with it.
As always, any comments are appreciated.
