Tom Quarendon commented on ARIES-1867:
--------------------------------------
[~csierra] I've been experimenting with your testVoidResourceWithFilter test.
Tomorrow I'll try and work out what's different for my case, or indeed whether
I can reproduce the scenario I was seeing any more. I definitely had a simple
@GET method that had a void return and wasn't having the CORS filter called.
I'll try and translate that into a test case, now I have your framework test
and can understand what it actually does.
BTW, would I expect all the other tests to run cleanly? I can't run "mvn clean
install" cleanly from the root directory, I get test case failures in the
ClassIntrospectorTest (testResourceWithSubresource and
testPlainResourceSeveralOperationsWithCommonPath). I also get a test case
failure in one of the integration tests (TEST
testApplicationEndpointExtensionRuntimeDTO(test.JaxrsTest) <<< ERROR:
expected:</[\{name}]> but was:</[]>).
Thanks.

> Key: ARIES-1867
> URL: https://issues.apache.org/jira/browse/ARIES-1867
> Project: Aries
> Issue Type: Bug
> Components: jax-rs-whiteboard
> Affects Versions: jax-rs-whiteboard-1.0.2
> Reporter: Tom Quarendon
> Assignee: Carlos Sierra
> Priority: Blocker
> Attachments: CORSFilter.java, Server.java, TestService3.java
>
>
> I have a resource class such as the following:
> {code:java}
> @Path("events")
> @JaxrsResource
> public class EventsResource {
> private Sse sse;
> private SseBroadcaster eventBroadcaster;
> @Context
> public void setSse(Sse sse) {
> this.sse = sse;
> this.eventBroadcaster = sse.newBroadcaster();
> }
> @GET
> @Produces(MediaType.SERVER_SENT_EVENTS)
> public void suscribeToEvents(@Context SseEventSink eventSink) {
> eventBroadcaster.register(eventSink);
> }
> }
> {code}
>
>
> In addition, I have a CORS filter:
>
> {code:java}
> @Component(immediate=true)
> @Provider
> @JaxrsExtension
> public class CORSFilter implements ContainerResponseFilter {
> @Override
> public void filter(ContainerRequestContext requestContext,
> ContainerResponseContext responseContext) throws IOException {
> System.out.println("CORSFilter for
> "+requestContext.getUriInfo().getPath());
> MultivaluedMap<String, Object> headers = responseContext.getHeaders();
> headers.add("Access-Control-Allow-Origin",
> requestContext.getHeaderString("Origin"));
> ...
> {code}
>
> The CORS filter gets fired on all requests as I expect, _except_ for ones to
> the EventResource.subscribeToEvents method. Hence browsers complain when
> receiving SSE events.
> This used to work fine with jersey as the JAXRS implementation. CORS filter
> got called for the EventsResource.subscribeToEvents call.
> I've no idea whether this is a jaxrs-whiteboard level issue, or a CXF level
> issue. I will try and come up with a plain CXF test of the same thing for
> comparison.
