The amount of data to validate against could be fairly large though (i.e. city lookup, customer search, etc..,) and it will be coming directly from a database (i.e. MySQL for example). You are correct in that I would like to stay away from having to refresh the page and so forth. I was thinking that maybe I would have to take the route of inserting an
applet onto a page or something and using RMI in some way. I'm unfamilar with both but was thinking that this might be the best approach but since I normally deal with calling pages I was unsure of the best route to take for this. Any idea if AJAX would still apply based on the requirements I have above? Thanks.
