Yes, if you constantly change containers, then there is value in Atmosphere for that as it does leverage the native APIs for the container. We [lift] are waiting for servlet 3.0 to standardise the comet API - whilst its debatable if that will prove as an api standardisation solution, it should level the playing field somewhat - right now the different containers are all doing different things in different ways.
Essentially lift uses special classes within Jetty (the continuation API) to make comet scalable... there is nothing stopping comet working in other containers with lift, the only restriction is that it does not use the native container API so it's essentially thread based - to that end, if you have a lot of connections things could get sticky. Lift has things that Atmosphere does not have (yet) like the multiplex support, and object delta'ing... perhaps other comet frameworks will get this in the future, but right now, using Jetty is not a deal breaker for most of our users. I guess its only really an issue if you have a heavy investment in something that is not jetty. However, I would stress that lift is an excellent framework even if your not using comet and that would of course deploy without any issues in any container. I actually had a discussion with Jean-Francois at Devoxx this year about Atmosphere and Lift ;-) Cheers, Tim On 6 Jan 2010, at 12:40, Paul Sandoz wrote: > > On Jan 6, 2010, at 12:49 PM, Timothy Perrett wrote: > >> paksegu, >> >> Lift does have better comet support than Atmosphere, but it depends what >> your use case is and what you specifically want to do.
