JAX-RS and Jersey with AtmosphereRESTful and asynchronous Web applications
JAX-RS is the Java API for RESTful Web services
Jersey is the reference implementation and provides additional functionality
Atmosphere leverages the extensibility of Jersey
Atmosphere and Jersey can evolve at their own rates
Combine JAX-RS and Atmosphere annotations

High-level Atmosphere conceptsLeveraging the power of REST, JAX-RS/Jersey
@Suspend or SuspendResponse API
Suspend a response
@Resume
Resume a response
@Broadcast or Broadcaster API
Broadcast events
@Schedule
Schedule execution of periodic broadcast
@Cluster
Cluster broadcasting

We want a Twitter Real Time Search!

Conclusion
Write Powerfull Asynchronous Web Application using Atmosphere
Write once, Run Anywhere
Transport free!
Browser nightmare free
Extremely Simple!
