Depends on what you're willing to NOT support. Certain minor browsers
still don't support Javascript. Regardless, I'd advise sticking to the
HTML/CSS/Javasript(WebSockets/AJAX/Comet) approach. If you can support
all three of those then you should be covered (disclaimer: I would use
Comet as little as possible, and most likely only in whatever
"client-boot" code you may require).

WebSockets and AJAX should probably be considered alternatives to each
other. Involving Java seems to me to be patently unnecessary
(especially since you might be able to run multiple AJAX requests at
once).
