Asynchronous Method Dispatch in CXF?
I am planning to implement a set of services based on CXF.
What I know is when the function (i.e., method) is invoked at a server side,
the response message is sent to the client immediately after the function
returns.
Unlike this, I need to use asynchronous method dispatch (see below) at a
intermediate dispatcher.
client -> intermediate dispatcher -> actual server
client <- intermediate dispatcher <- actual server
http://en.wikipedia.org/wiki/Asynchronous_method_dispatch
<http://en.wikipedia.org/wiki/Asynchronous_method_dispatch>
That is, I want to know whether there is a way of sending the response later
but not immediately after the function returns.
Thank you in advance.

FYI, I've done a minor update to make sure all of the code needed to set
a field value runs as privileged, which may help in cases like this one.
where CGLIB proxies are used, but working with setters is always a safe
approach too
Cheers, Sergey

Re: Problem including @Context
Posted by Sergey Beryozkin <sb...@gmail.com>.
Hi,
what CXF version do you use ? I think the injection code should work ok
in the later CXFs. An immediate workaround: introduce a setter like
@Context
public void setHttpServletResponse(HttpServletResponse resp);
and possibly move it to a dedicated interface (to be implemented by the
resource class)
Thanks, Sergey

My server setup looks like this, i thought maybe i need to do something
differently as my service class is managed by Spring?

Problem including @Context
Posted by Nic Fellows <ni...@thebookpeople.co.uk>.
I am trying to access the HttpServletResponse in my @Service
I'm at a bit of a loss as to why it wont work, can anyone point me in
the right direction?
Id supply more information but i'm not sure what you will need!
Thanks!
The code is:
@Service("reviewRestService")
@Path("/gabble")
public class DefaultGabbleRestService implements GabbleRestService {
@Context
public HttpServletResponse response;
...
The root exception looks like this:
Caused by:
java.lang.IllegalArgumentException: Can not set javax.servlet.http.HttpServletResponse field uk.co.tbp.gabble.rest.DefaultGabbleRestService.response to com.sun.proxy.$Proxy80

RE: Asynchronous Method Dispatch in CXF?
Posted by Andrei Shakirin <as...@talend.com>.
Hi,
You can use @UseAsyncMethod annotation available since CXF 2.6.0: http://cxf.apache.org/docs/annotations.html .
If transport supports it, CXF will use async version of the method, if not - sync version will be invoked.
Regards,
Andrei.

Re: Asynchronous Method Dispatch in CXF?
Posted by Sergey Beryozkin <sb...@gmail.com>.
Hi
You can use CXF-specific Continuations API, this will work for both JAX-WS
& JAX-RS,
for example:
http://svn.apache.org/repos/asf/cxf/trunk/systests/transports/src/test/java/org/apache/cxf/systest/http_jetty/continuations/
(WS), the same approach (in the server code) will work for RS
If it is JAX-RS, then using JAX-RS 2.0 AsyncResponse will help:
http://svn.apache.org/repos/asf/cxf/trunk/systests/jaxrs/src/test/java/org/apache/cxf/systest/jaxrs/BookContinuationStore.java
Let me know if you have some questions,
Sergey
