Re: fine grained authorization based on DN/X.509
Thanks for the reply.
I have few comments on your reply.
Usually the certificate received at the server side has atleast 2
certificates - one is a public key of the client and the rest are n
trusted entries (in my case it is 1).
As you have mentioned about the getRequest() method, where do you access it
in a resource or in a application class? I am intercepting the requests in
an application class (which extends from JaxRsApplication), whereby I am
overriding the handle(req,res) method and and getting the desired
attributes, is the following were you referring to?:
public class MyJaxRsApplication extends JaxRsApplication{
@Override
public void handle(Request request, Response response) {
Maplt;String, Objectgt; map = request.getAttributes();
@SuppressWarnings(unchecked)
ListX509Certificate lst = (ListX509Certificate)
map.get(org.restlet.https.clientCertificates);
//however the first item in the above list is the user's public key
//here, delegation to the authorization PEP, PAP and PIP will be made
}
..
}
Many thanks

Is JAX-RS in Restlet experimental?
Hi, I have just found while checking out jaxrs and test project's source code, where the author is clearly stating that the support for jaxrs within restlet is experimental.

Upgrading to the latest restlet snapshot solved the case.

RE: ObjectRepresentation with an Object embedding a negative int value
Sorry for the late reply. I created a small application, containing an object that wraps an int and a double. I choose for the double because on my project I recently came across a bug which wouldn't allow me to send the value 51.84455752. Thought 51.84455751 and 51.84455753 work fine, seems rather odd to me. But I could not reproduce that in this project. It could be the problems are related to eachother. Anyways, I created an Android 2.2 application and Google App Engine application. In MainActivity.java (Android project) on line 18 the appEngineUrl should be changed to the location the App Engine application is hosted. Downloads at: http://stud.hro.nl/0812933/ICTLAB/NumbErrors%20Android.zip http://stud.hro.nl/0812933/ICTLAB/NumbErrors%20GAE.zip Thank you in advance. -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=2759137
Re: IncompatibleClassChangeError with ConcurrentMap
Hi Sebastian,
I think I ran into the same issue like you have been described initially.
Switching to 2.1 Snapshot (2011-06-01) solved this issue for me.
Regarding you second issue - my code looks slightly different and provides
valid json representation back. Maybe this works for you as well.
Actually I'm not creating the JSONRepresentation by myself but just provide
pure Java Objects back. The JSON-serialization is then handled by restlet
itself. I'm using the Jackson-extension.
Code looks similar to:
@Get
public MyResponseClass get(){
myResponseClass response = new MyREsponseClass();
// some fany but unimportant stuff here ...
setStatus(Status.SUCCESS_OK);
return response;
}
If I call with accept=application/json, I get a Json response like expected.
Maybe that helps?
Cheers,
Stefan

Re: IncompatibleClassChangeError with ConcurrentMap
Hi Sebastian:
I am using JsonRepresentation and it works just fine.
Did you enable JSON by addding the variant in the constructor of your resource?
getVariants().add(new Variant(MediaType.APPLICATION_JSON));
And maybe your annotation should be @Get(json) as well.
Hope that helps,
Jason

The Status is correctly set, as well as the JsonRepresentation as the

Re: IncompatibleClassChangeError with ConcurrentMap
Hello Sebastian,
what version of GAE are you using?
As a side question, I wonder why you don't let the client specify it's
preferred kind of representation.
On the server side :
@Get
public SomeJsonObject get(){
return someJsonObject;
}
If your aplication contains at least, the jackson extension
(org.restlet.ext.jackson.jar + its jackson dependencies that are shipped
with the restlet distribution), the server is able to convert the object
using its converter.
If you add the gwt extension (not the *edition*) of any of these editions
(jse, jee, gae), your server is able to generate and deserialize
representations coming from the GWT client.
Did you have a look at this sample code?
http://wiki.restlet.org/docs_2.1/13-restlet/303-restlet.html
Having said that, I really don't understand why the server does not send the
Representation back.
What archives are located in the classpath?
Best regards,
Thierry Boileau

Re: fine grained authorization based on DN/X.509
That's one way to do it, but it isn't the way I usually design my restlet
applications.
I do all of my authentication and authorization in subclasses of the restlet
API classes, which are subclasses of filter. These typically sit in front
of your resources in a filter chain, which you configure in your router set
up in createInboundRoute in your subclass of Application.
Steps 9-12 of http://www.restlet.org/documentation/2.0/tutorial have an
example that may be useful to you. But if what you have works for your
situation, then it looks like you're on the right track. It just may be
harder to re-use your code in other restlet applications later on.

Hello Thierry,
i have to ask my person in charge tomorrow if it's alright to share some
sample code.
Some thing i noticed is that the size property of the JsonRepresentation is
set to -1.
Maybe that's the problem?
Here's what the JsonRepresentation looks like:
available=true
characterSet=UTF-8
encodings=[]
indenting=false
indentingSize=3
isTransient=false
jsonRepresentation=null
jsonValue=JSONObject {count:2}
languages=[]
mediaType=application/json
size=-1

I think what should be called is getBestHelper(Representation
source,ClassT target, UniformResource resource).
Don't know yet why it's called like this though.
Hmm...of course that's not the problem either.
DefaultConverter is used for Representations,and it returns a valid
JsonRepresentation with a jsonValue set to my JSONObject.
That's returned by the ServerResource in doHandle() later and is also set as
the Response-Entity...
I'm really hitting the end of the road here.
