---------------------------------

             Summary: Non-blocking WS call with CXF
                 Key: CXF-5942
                 URL: https://issues.apache.org/jira/browse/CXF-5942
             Project: CXF
          Issue Type: Wish
          Components: Transports
    Affects Versions: 3.0.0-milestone1
            Reporter: Bence Takács
            Priority: Minor


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();
            log.info(person.getName() + " | " + person.getAge() + " | " +
                person.getDescription());
            Assert.assertNotNull(person);
            Assert.assertNotNull(person.getName());
        } catch (InterruptedException | ExecutionException e) {
            log.error("EXCEPTION WHILE PROCESSING RESPONSE CALLBACK");
        e.printStackTrace();
        }
    }
});
{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
