Which open-source comet/ reverse-ajax libraries will you recommend to be used with Tomcat 5.5? Why? [closed]

Question

I have seen continuations in Jetty 6.0 that addresses scaling for comet/reverse-ajax applications.

Are there any other libraries/frameworks to be used with Tomcat 5.5?

Answer 1

Atmosphere is the kind of thing I was looking for.

Answer 2

I would check out DWR(Direct Web Remoting). It has fairly decent documentation and a respectable user base.

DWR

Answer 3

ItsNat Comet works with Java 1.4 JVMs including Tomcat 5.5 with this JVM, of course upper versions of Java and servlet containers are supported.
