I may have a chance to work with ajax.

1 it doesn't sound like there's a need for a controller - any controller?
2 there is some need for this technology but it is deep or will it be? the client wants windows-like responsiveness on the web. i've been told that google maps was done in ajax.

I did read 4 threads about it on here and found https://dwr.dev.java.net/. I can integrate with spring.

I appreciate any thoughts you can post here.
