> Key: CAMEL-8370
> URL: https://issues.apache.org/jira/browse/CAMEL-8370
> Project: Camel
> Issue Type: Task
> Components: documentation
> Affects Versions: 2.14.1
> Reporter: Mark Mindenhall

> Priority: Minor
> Fix For: 2.15.0

> I sent the following to the [email protected] list earlier today:
> {quote}
> I’m using the camel-netty4-http (latest 2.14.2-SNAPSHOT) component to create
> an endpoint that receives an HTTP POST from a device, translates the message
> from binary to JSON, then sends it along to a kafka topic for further
> processing. When there are errors in validating or translating the incoming
> message, I need to be able to return a HTTP response code and response body.
> The camel-netty4-http documentation has an “Access to Netty types” section,
> which says that I should be able to do the following to access the instance
> of io.netty.handler.codec.http.HttpResponse:
> HttpResponse response =
> exchange.getIn(NettyHttpMessage.class).getHttpResponse();
> Regardless of where I access the exchange within the route, getHttpResponse()
> is always returning null. On the "happy path” I can return 200 by calling
> exchange.getOut().setBody(myResponse), but I have been unable to figure out
> how to return another response code.
> Is this a bug? Or is there another way to accomplish what I’m trying to do?
> {quote}
> After digging around in the code, it looks like the HTTP status code is set
> via the CamelHttpResponseCode message header
> (org.apache.camel.component.netty4.http.DefaultNettyHttpBinding, line 308).
> However, there is no mention of this message header in either the
> camel-netty-http or camel-netty4-http documentation. It would be helpful to
> add this header to the list of applicable message headers, and also to
> include an example that demonstrates how to set the response status code and
> body:
> Finally, the existing "Access to Netty types" example should be modified to
> be clear that only the request can be accessed in this way.
> {code}
> // specify response body and status
> exchange.getOut().setBody(myResponseBody);
> exchange.getOut().setHeader(Exchange.HTTP_RESPONSE_CODE, 401);
> {code}
