Yep, I know that.  Was seeing the issue either way, and as far as I know
the AsyncResponse approach is the more spec appropriate way.

It is only needed in this case to init a CXF-specific subscriber hence a 
portability issue while without it one would have a portable code 
consistent with the way CompletableFuture is supported in 2.1 - where 
you just return it...



In the servlet container you may need to enable the async (via the
standard servlet param).



haha, that was it.  Thanks!

Np, sometimes it is probably not needed, I thought I saw some examples 
before where it just works, may be some servlet containers are stricter...

That dependency you referred to should let you do:

 @Path("/")
 public class RestController {
  @GET
  @Produces(MediaType.APPLICATION_JSON)
  public Flux doGet(@Suspended AsyncResponse asyncResponse) {
  ClientBuilder.newClient()
  .register(MyAppFeature.class)

Reactive Services & CDI

2018-02-04 Thread John D. Ament

I built a simple webapp (WAR file, deploying to Tomcat) that depends on the
CXF 3.2.2 libraries + Weld 3.0.2.  I don't believe CDI has anything to do
with my problem though.

I registered a feature/server customizer that can deal with the invoker
logic required, and provided a rest controller that simply invokes the
postman echo service

Feature/Extension:

@ApplicationScoped
public class MyAppFeature implements Feature,
JAXRSServerFactoryCustomizationExtension {
public boolean configure(FeatureContext featureContext) {
featureContext.register(JsrProvider.class);
featureContext.register(ReactorInvokerProvider.class);
return true;
}

@Override
public void customize(JAXRSServerFactoryBean jaxrsServerFactoryBean) {
ReactorInvoker invoker = new ReactorInvoker();
invoker.setUseStreamingSubscriberIfPossible(false);
jaxrsServerFactoryBean.setInvoker(invoker);
StreamingResponseProvider streamProvider = new
StreamingResponseProvider<>();

streamProvider.setProduceMediaTypes(Collections.singletonList("application/json"));
jaxrsServerFactoryBean.setProvider(streamProvider);
jaxrsServerFactoryBean.getOutInterceptors().add(new
LoggingOutInterceptor());
}
}

RestController:

@RequestScoped
@Path("/")
public class RestController {
@GET
@Produces(MediaType.APPLICATION_JSON)
public void doGet(@Suspended AsyncResponse asyncResponse) {
ClientBuilder.newClient()
.register(MyAppFeature.class)
.target("https://postman-echo.com/get;)
.queryParam("arg1", "arg1")
.queryParam("arg2", "arg2")
.request(MediaType.APPLICATION_JSON_TYPE)
.rx(ReactorInvoker.class)
.get(JsonObject.class)
.subscribe(new
JsonStreamingAsyncSubscriber<>(asyncResponse));
}
}

When I attempt to invoke this endpoint, I see a NPE in the logs
