Re: Multiple content types
Hello Sherif,
I've tried with your sample code, and it works for me.
I've just changed this piece of code, in the "represent" method:
MediaType mediaType = variant.getMediaType();
if (MediaType.APPLICATION_JSON.equals(mediaType))
I send you my sample code, that, I've tested it with Restlet 1.1 and
Restlet 1.2 (current trunk in both cases) .
Best regards,
Thierry Boileau

RE: Re: Multiple content types
Hi Sherif,
Could you send us the trace of your HTTP request/response exchange including
HTTP headers? I suscept that you "Accept" header might not be correct.
Best regards,

Re: Multiple content types
Hi Sherif,
.js is javascript
.json is json :0)
There is no need to add js or json to the MetadataService as it comes
with a bunch of common ones already.
Remove that line, and try
http://localhost:8080/firstStepsServlet/Hello.json (Notice the JSON)

RE: Multiple content types
Thanks Jonathan..
1. Here's what I did to support lets say ".js" as an extension to
indicate JSON as the content type
public class FirstStepsApplication extends Application {
/**
* Creates a root Restlet that will receive all incoming calls.
*/
@Override
public Restlet createRoot() {
// Create a router Restlet that routes each call to a
// new instance of HelloWorldResource.
Router router = new Router(getContext());
// Defines only one route
router.attachDefault(HelloWorldResource.class);
this.getTunnelService().setExtensionsTunnel(true);
this.getTunnelService().setEncodingParameter("output");
this.getMetadataService().addExtension("js", new
Metadata(MediaType.APPLICATION_JSON.getName(),
MediaType.APPLICATION_JSON.getDescription()), true );
return router;
}
}
public class HelloWorldResource extends Resource {
public HelloWorldResource(Context context, Request request, Response
response) {
super(context, request, response);
// This representation has only one type of representation.
getVariants().add(new Variant(MediaType.TEXT_PLAIN));
getVariants().add(new Variant(MediaType.APPLICATION_JSON));
}
/**
* Returns a full representation for a given variant.
*/
@Override
public Representation represent(Variant variant) throws
ResourceException {
Representation representation = null;
if(variant.getMediaType() == MediaType.APPLICATION_JSON){
representation = new JsonRepresentation("Hello World");
}else if ( variant.getMediaType() == MediaType.TEXT_PLAIN){
representation = new StringRepresentation(
"hello, world", MediaType.TEXT_PLAIN);
}
return representation;
}
}
However when I call the service using the following URL
http://localhost:8080/firstStepsServlet/Hello.js the Variant type in the
HelloWorldResource is of MediaType.TEXT_PLAIN
Thanks for Your help
