Excellent thank you both for your replies. I missed the rule that every
Representation is a Resource to be honest, and that's good to know now.
Here is my code:
Client client = new Client(Protocol.HTTP);
Request request = new Request(Method.GET,
"http://www.mysite.com/users?media=application/x-java-serialized-object";);
request.setChallengeResponse(....);
Response response = client.handle(request);
Representation representation = response.getEntity();
Why is representation always an InputRepresentation and not the one that
was asked for? The correct ObjectRepresentation is now being returned
from my Resource (thanks!), but the Response in this case never returns
the right one. Is this intentional?
Thanks!

Hello,
Just a few words to complete Jonathan's responce.
The next question is "how can I request this specific representation?".
Let's say that you define the URI of your User resource like this =>
http://my.company.org/users/<id>.
On the client side, if you have a full control of the HTTP request,
you can set the requested URI with http://my.company.org/users/<id>
and set the ACCEPT header with the right media-type.
If not, for example with your favorite browser, there is one solution
based on the Tunnel service [1]. If the Tunnel service is running on
server side (e.g. in an Aplication), you can rely on the
"mediaTypeParameter".
It just says that if your browser requests for
"http://my.company.org/users/<id>?media=application/x-java-serialized-object"
then the Tunnel Filter updates the request on fly by replacing the
media-types preferences sent by the browser with the single preference
"application/x-java-serialized-object". Then the Resource will return
the right representation.
This solution has another effect : it complies with the rule saying
that every Representation is a Resource, and thus is identified by its
own URI(s).
best regards,
Thierry Boileau

Hi Justin,
If I understand you, you want to return html,text and an object for a
resource?
Simplest form
public class MyResource extends Resource {
public MyResource(Context context, Request request, Response response) {
super(context, request, response);
getVariants().add(new Variant(MediaType.APPLICATION_JAVA_OBJECT));
getVariants().add(new Variant(MediaType.TEXT_PLAIN));
getVariants().add(new Variant(MediaType.TEXT_HTML));
}
@Override
public Representation getRepresentation(Variant variant) {
Representation rep = null;
if (MediaType.TEXT_PLAIN.equals(variant.getMediaType())) {
rep = StringRep...
}
else if (MediaType.TEXT_HTML.equals(variant.getMediaType())) {
rep = Freemarker...
}
else if
(MediaType.APPLICATION_JAVA_OBJECT.equals(variant.getMediaType())) {
rep = ObjectRepresenation( YOUR_SERIALIZED_OBJECT );
}
return rep;
}
}
Your client sending:
Accept: application/x-java-serialized-object
works fine on 1.1 snapshot, sorry I dont have a test setup for 1.0.8.
