How to log request payload when using Camel Rest?

I'd like to log the original 'raw' request body (e.g. JSON) while using Camel Rest endpoints. What's the proper way to do this?
My setup (RouteBuilder) looks like this:
restConfiguration().component("jetty")
.host(this.host)
.port(this.port)
.contextPath(this.contextPath)
.bindingMode(RestBindingMode.json);
rest("myService/").post()
.produces("application/json; charset=UTF-8")
.type(MyServiceRequest.class)
.outType(MyServiceResponse.class)
.to(SERVICE_CONTEXT_IN);
from(SERVICE_CONTEXT_IN).process(this.serviceProcessor);
My problem here is that the mechanics such as storing the request as an Exchange property are 'too late' in terms of using this approach, any processors are too late in the route, i.e., the binding already took place and consumed the Request. Also the CamelHttpServletRequest's InputStream has already been read and contains no data.
The first place to use the log EIP is directly before the single processor:
from(SERVICE_CONTEXT_IN).log(LoggingLevel.INFO, "Request: ${in.body}")
.process(this.serviceProcessor);
but at that point the ${in.body} is already an instance of MyServiceRequest. The added log above simply yields Request: x.y.z.MyServiceRequest#12345678. What I'd like to log is the original JSON prior to being bound to a POJO.
There seems to be no built-in way of enabling logging of the 'raw' request in RestConfigurationDefinition nor RestDefinition.
I could get rid of the automatic JSON binding and manually read the HTTP Post request's InputStream, log and perform manual unmarshalling etc. in a dedicated processor but I would like to keep the built-in binding.

I agree there is no way to log the raw request (I assume you mean the payload going through the wire before any automatic binding) using Camel Rest endpoints.
But taking Roman Vottner into account, you may change your restConfiguration() as follows:
restConfiguration().component("jetty")
.host(this.host)
.port(this.port)
.componentProperty("handlers", "#yourLoggingHandler")
.contextPath(this.contextPath)
.bindingMode(RestBindingMode.json);
where your #yourLoggingHandler needs to be registered in your registry and implement org.eclipse.jetty.server.Handler. Please take a look at writing custom handlers at Jetty documentation http://www.eclipse.org/jetty/documentation/current/jetty-handlers.html#writing-custom-handlers.

In the end I 'solved' this by not using the REST DSL binding with a highly sophisticated processor for logging the payload:
restConfiguration().component("jetty")
.host(this.host)
.port(this.port)
.contextPath(this.contextPath);
rest("myService/").post()
.produces("application/json; charset=UTF-8")
.to(SERVICE_CONTEXT_IN);
from(SERVICE_CONTEXT_IN).process(this.requestLogProcessor)
.unmarshal()
.json(JsonLibrary.Jackson, MyServiceRequest.class)
.process(this.serviceProcessor)
.marshal()
.json(JsonLibrary.Jackson);
All the requestLogProcessor does is to read the in body as InputStream, get and log the String, and eventually pass it on.

You can solve this by:
Turning the RestBindingMode to off on your specific route and logging the incoming request string as is.
After which you can convert the JSON string to your IN type object using ObjectMapper.
At the end of the route convert the java object to JSON and put it in the exchange out body, as we turned off the RestBindingMode.
rest("myService/").post()
.bindingMode(RestBindingMode.off)
.to(SERVICE_CONTEXT_IN);

In my case, streamCaching did the trick because the Stream was readable only once. Thefore I was able log but was not able to forward the body any more. I hope this might be of help to someone

Camel Rest DSL Response Codes

I have a route builder that looks as follows:
.post("/myEndpoint")
.type(MyObject.class)
.to("bean:myListener?method=create")
I would like this to return a 201 Created HTTP Response Code, at present its returns a 200 OK.
Is there a way to do this in the RouteBuilder without having to forward any results onto a separate service class and then manually set the code on the Exchange?

We managed to get it to work by doing the following -
.post("/myEndpoint")
.type(MyObject.class)
.route()
.setHeader(Exchange.HTTP_RESPONSE_CODE,simple(HTTP_CREATED))
.to("bean:myListener?method=create")
.endRest()

See the header section here http://camel.apache.org/constant.html for setting headers.. You should be able to set the http response code and body directly.

Returning file/files in JSON response (Java-Jersey-ReST)

I am working on a use case where I am displaying user's messages on a JSP. Details of the flow are:
All the messages will be shown in a table with icon for attachments
When the user clicks on attachment, the file should get downloaded.
If there is more than one attachment, user can select the required
one to download.
The attachments will be stored on the local filesystem and the path for the attachments will be determined by the system.
I have tried to implement by referring to these SO questions:
Input and Output binary streams using JERSEY?
Return a file using Java Jersey
file downloading in restful web services
However, it's not solving my purpose. I have the following questions:
Is it possible to send message data (like subject, message, message id, etc) along with the attachments (Inputstream) in one response?
If yes, what needs to be the MediaType for #Produces annotation in my resource method? Currently my resource is annotated with #Produces(MediaType.APPLICATION_JSON). Will this work?
How to send the file data in the response?
Any pointers appreciated. TIA.

You can add custom data to the response Header, so yes you are able to send such message data. Add the data to the response Header.
#Produces(MediaType.APPLICATION_JSON) will not work, unless the clients will accept JSON as a file, what they should and will not do ;)
The correct MediaType depends on what kind of file you want to submit.
You can use the default MediaType / MIME-Type MediaType.APPLICATION_OCTET_STREAM / application/octet-stream (Is there a “default”
MIME type?) but I think it's better to use the correct and exact MIME-Type for your file.
You will find working examples for sending file data with jersey in Input and Output binary streams using JERSEY? - so there is no need to answer this again :)
Hope this was helpful somehow, have a nice day.

How do I get Rest Assured to return the text (non-encrypted or streamed) value in my REST response?

I recently moved over to Java and am attempting to write some REST tests against the netflix REST service.
I'm having an issue in that my response using rest assured either wants to send a gzip encoded response or "InputStream", neither of which provide the actual XML text in the content of the response. I discovered the "Accept-Encoding" header yet making that blank doesn't seem to be the solution. With .Net I never had to mess with this and I can't seem to find the proper means of returning a human readable response.
My code:
RestAssured.baseURI = "http://api-public.netflix.com";
RestAssured.port = 80;
Response myResponse = given().header("Accept-Encoding", "").given().auth().oauth(consumerKey, consumerSecret, accessToken, secretToken).param("term", "star wars").get("/catalog/titles/autocomplete");
My response object has a "content" value with nothing but references to buffers, wrapped streams etc. Trying to get a ToString() of the response doesn't work. None of the examples I've seen seem to work in my case.
Any suggestions on what I'm doing wrong here?

This has worked for me:
given().config(RestAssured.config().decoderConfig(DecoderConfig.decoderConfig().noContentDecoders())).get(url)

I guess in Java land everything is returned as an input stream. Using a stream reader grabbed me the data I needed.

Until its version 1.9.0, Rest-assured has been providing by default in the requests the header "Accept-Encoding:gzip,deflate" with no way of changing it.
See
https://code.google.com/p/rest-assured/issues/detail?id=154

It works for me:
String responseJson = get("/languages/").asString();

Restlet response to POST request

First off, I'm using an older version of Restlet (1.1).
Secondly, I'm not sure I'm doing the correct thing. Here's what I'm trying to do...
I'm creating a reporting service (resource). I'd like my service to listen for POST requests. The body of the request will contain the report definition. I'd like the response to be the CSV file generated by the service (the report). Is responding to a POST request in this manner OK from a REST standpoint (if not, then how to refine this resource)?
I can't seem to figure out how the acceptRepresentation() generates the response. I've tried setting the Representation parameter passed into the method to a new FileRepresentation. I've also tried to utilize the represent() method, but it doesn't seem like that method is called as part of the POST processing.
How can I accomplish this seeming easy task?

Calling the getResponse().setEntity() method from acceptRepresentation() will accept the new FileRepresentation and accomplish what I'd like to.
