JAX-WS async service

I understand that async invocation can be used on the client side but is there something on the server side as well? JAX-RS 2.0 introduced a truly async server side capability, wondering if JAX-WS has something similar.

To answer my own question, there doesn't seem to be direct support for async service. The service may provide a special method for polling or if the client itself is a Web Service, can callback on a replyTo address.

Just to get an idea with some nice pictures: Oracle Async Web Services.

I read that. Seems that there is no 1st class support for server side asynchrony; I mean, calling back to a client who itself is a Web Service doesn't seem like 1st class support to me. Thing is, when the client makes an async call, the server will still be busy working on it. Even though the client returns immediately from a non-blocking call, it doesn't reduce the load on the server side.

Agree, it doesn't look like the best support, but when using MDB's at least the load on the server side is handled well. Additional MDB's are pulled in (or pooled in ) when needed.
