SpringCloudStream-HttpSource is returning 404 - spring-cloud

Question

I am working on the Brooklyn.Release version of SpringCloudStream. My use case has HttpSource with Mutiple Sinks. When I added the Starter App dependency to the application and using it as below:
<dependency>
<groupId>org.springframework.cloud.stream.app</groupId>
<artifactId>spring-cloud-starter-stream-source-http</artifactId>
<version>1.0.4.RELEASE</version>
</dependency>
#SpringBootApplication
#Import(HttpSourceConfiguration.class)
public class SourceApplication {
public static void main(String[] args) {
SpringApplication.run(SourceApplication.class, args);
}
}
My Aggregate App is
#SpringBootApplication
public class Application {
public static void main(String[] args) {
new AggregateApplicationBuilder().from(SourceApplication.class)
.via(ProcessorApplication.class).to(SinkApplication.class).args().run(args);
}
}
Getting the following response as below all the time:
<Fault xmlns="http://localhost/">
<error>Not Found</error>
<message>No message available</message>
<path>/</path>
<status>404</status>
<timestamp>1477612242743</timestamp>
</Fault>
Added ComponentScan for HttpSourceConfiguration(Out of the Box); but no success.
#SpringBootApplication
#ComponentScan(value = {"com.xxx.xxx.stream","org.springframework.cloud.stream.app.http.source"})
public class Application {
public static void main(String[] args) {
new AggregateApplicationBuilder().from(SourceApplication.class)
.via(ProcessorApplication.class).to(SinkApplication.class).args().run(args);
}
}
If I use the same SourceApplication with Rabbit Binder, it is working as expected. Can you please guide me in getting this working?
Appreciate your help and time.

The REST endpoints don't seem to be setup and it looks like you may be running into this issue. You would need #ComponentScan for the package where HttpSourceConfiguration is (since it is from a different package).
If I use the same SourceApplication with Rabbit Binder, it is working as expected.
Do you mean the out of the box http app with the rabbit binder or you just added the rabbit binder dependency in the above SourceApplication?
Usually you prefer using the http source application that comes out of the box (with any of the associated binder), but for the aggregate application you don't need the binder unless you have input or output of the aggregate app itself is bound to a broker.
