Hi,
I'm using CXF between two endpoints (both are AS) in SOAP and/or REST
over
HTTP.
I want network callflows to be as simple as possible (no callbacks, plain
simple request/answer) and i want to be resources-efficient because some
requests might be long (and i'll have long-polling for events).
So, I need to have asynchronous implementations (in java) of both client
and servers.
Here is where i stand:
SOAP (jax-ws) :
- asynchronous client : OK (wsimport + binding.xml)
- asynchronous server : not supported yet by CXF (AsyncProvider is
specified in jax-ws 2.2, it's not the most simple to implement (handle
the
XML myself...) but it should be able to do the job, might be supported in
jax-ws-ri by sun).
REST (jax-rs) :
- asynchronous client (cxf-wadl2java) : ? i did find anything about
asynchronous client and I really hope someone can give me a pointer
I guess we can extend cxf-wadl2java to get "@Suspended AsyncResponse"
added to the generated signature if a current method id is listed,
example, "-async getIt", where "getIt" is the name or id of some
specific WADL method element. I'll think about it...
The code generator has been updated on the trunk to support "-async"
option, for example, '-async get,addBook' where 'get' will match all
WADL methods with name "GET", and 'addBook' - a specific method with id
attribute 'addBook'
"-managedAsync" option for supporting "@UseAsyncMethod" style will be
added later...

However, that will only help with preparing the server code, the proxy
based client code will not be able to run in the async mode itself, it
is only possible to use WebClient for the client code itself to run
asynchronously.
thanks, Sergey
- asynchronous server : OK using AsyncResponse (jax-rs 2.0) and some
fixes
that i'll post once i've tested a bit more
For now, I feel like there are some pieces missing.
Of course i could implement a REST client myself, but i feel it's a
waste.
There are libraries and utilities everywhere and what I want to do seems
pretty much in the scope of jax-rs and jax-ws).
Thanks in advance.
