Thanks to Frank Greco and everyone who came out to see my presentation at the NY JavaSIG. I got some great questions and it looked like a lot of people were starting to understand the problems with interactive applications using HTTP. BAM is the way to go! Anyway, here are the slides from my presentation: NY JavaSIG slides on BAM/HMTP
And, a correction: During my presentation, I stated that there is no standard intereface for Comet on the server. While technically true, the new Servlet 3.0 draft spec has an API. Someone mentioned this during the Q&A and I said that while I had looked at the spec, I didn’t actually see the Comet references in there. Well, they are there in Section 220.127.116.11. I haven’t had a chance to review the spec thoroughly, but it looks like a nice compromise. Webtide’s Greg Wilkins has a nice intro here that features Comet use cases in Servlet 3.0. There were a lot of attempts to create Comet APIs from us, Jetty, Tomcat, and Glassfish, so if we can standardize on something reasonable, that will help everyone. It still doesn’t change the fact that HTTP was not designed for this kind of interaction though.
