[jax-rs-spec users] Re: Handling HTTP request-response exchange asynchronously in JAX-RS

 There is no support for non-blocking I/O in JAX-RS 2.0. It is one of the features planned for JAX-RS 2.1 in Java EE 8. At this point, if you're interested in a portable solution, you'd need to build this on top of Servlet 3.1.

 Hope this helps.
