There should be a default Java sevlet available in the Domino server, which would perform DBlookup and DBColumn functionality for any Web Based form, using AJAX.
Yes a Notes agane can be written, and aswell as a Servlet be written to. But if by default a servlet is there as standard for DBlookups and DBColumn, everyone accross, would not have to invent the wheel every time.
Suggesting an Idea of a servlet. to increase efficency in response.
