> It is not clear which are the use cases when one can use asynchronous client calls. The possible use cases would be:
> - server-side implemented callback transport
> - server-side implemented polling transport
> - client-side only callback using non-blocking IO
> However http.asyncclient supports all of them, I see no sign of CXF supporting the last one. Is there a way of calling a server this way?
> Using the configuration below I tried to call a WS this way, but CXF is always looking for async binding on the server side (javax.xml.ws.WebServiceException: Could not find wsdl:binding operation info for web method getDataFromWebService_Async). 
> Client configuration:
> {quote}
> <jaxws:client id="client"
>     serviceClass="my.sample.SampleWebService"
>     address="http://localhost:8080/sample-ws-cxf/SampleWebService">
>     <jaxws:properties>
>         <entry key="javax.xml.ws.client.connectionTimeout" value="10" />
>         <entry key="javax.xml.ws.client.receiveTimeout" value="11000" />
>         <entry key="org.apache.cxf.transport.http.async.usePolicy" value="ALWAYS" />
>         <entry key="org.apache.cxf.transport.http.async.ioThreadCount" value="2" /> 
>     </jaxws:properties>
> </jaxws:client>
> {quote}
> code:
> {quote}{noformat}
> client.getDataFromWebService_Async("" + id.getAndIncrement(), new AsyncHandler<Person>() {
>     @Override
>     public void handleResponse(Response<Person> resp) {
>         Person person;
>         try {
>             person = resp.get();
>             ...
>         } catch (InterruptedException | ExecutionException e) {
>             ...
>         }
>     }
> });
> {noformat}{quote}
> If I log out the conduit, it tells that it is: org.apache.cxf.transport.http.asyncclient.AsyncHTTPConduit ( log.info(ClientProxy.getClient(client).getConduit().getClass().getName()); )
> I'm using cxf 3.0.1, and httpasyncclient version 4.0.1 with spring 3.2.2.RELEASE
