Re: Matlab With Restlet
Hi, it looks like the containsAll methods behaves oddly, it should return true for both com.noelios.restlet.ext.net.HttpClientHelper, and com.noelios.restlet.http.StreamClientHelper. What may happen also is that the client is not properly initialized. Given its single protocol (HTTP), its member attribute protocols, which is a list, is set using the Arrays#asList method. Could you check that this method works properly by displaying the list of client's protocols? Client client = new Client(Protocol.HTTP); System.out.println(client.getProtocols()); If the list is empty, I suggest, as a workaround, to set the list using another way such as: client.setProtocols(new ArrayListProtocol()); client.getProtocols().add(Protocol.HTTP); Best regards, Thierry Boileau NB: Restlet v2 does not have a com.noelios.restlet package and jar. The org.restlet.jar contains now both the API and reference implementation. hi Thierry I have done the test suggested by you.Im using Restlet 1.1.8.Also i have downloaded (version 2 milestone 7 but i was not able to find com.noelios.restlet.jar inside lib folder.

RE: XML mapper for GWT
Hi Jerome, sounds good! I looked into ClientProxyGenerator.generateMethod() and noticed that the conversion is currently done using ObjectRepresentationT. If I get it right you want to replace this by the client side ConverterService? Do you already have something in place or are you in the design phase? Let me know as soon as you have something I can contribute to. The idea to extend Piriti to also support other formats like JSON definitely makes sense. I will add this to the next major release of Piriti and let you know when it is ready to use.

Minimum GWT code for ClientResource from a different host
Hi,
Could anyone please tell a rookie if there is any server side code
absolutely necessary in order to fetch data from a remote host? Later on I
will want to add authentication...
I have set up a working testGwtRestlet-2-0 example and added following lines
to onModuleLoad:
ClientResource r = new
ClientResource(http://www.remotedomein.com/RESTfulTest/resources/customers/pkey/2176172632;);
r.setOnReceived(new Uniform() {
public void handle(Request request, Response response) {
System.out.println(request.getResourceRef(): +
request.getResourceRef());
System.out.println(response.getStatus(): +
response.getStatus());
}
});
r.get();
as a debug message a get:
request.getResourceRef():
http://www.remotedomein.com/RESTfulTest/resources/customers/pkey/2176172632
response.getStatus(): Internal Connector Error (1002) -
(NS_ERROR_NOT_AVAILABLE): Component returned failure code: 0x80040111

Thank you for your help.

GWT, ClientResource, Same Origin Policy (SOP)
Good evening everyone,
What do I need to make from GWT a simple (GET and PUT) request to a
non-localhost service without having to implement any server side code? The
following example does not work. (Probably becouse of the Same Origin
Policy):
ClientResource r = new
ClientResource(http://xxx.xxx.xxx.xxx:/services/my_service;);
r.setOnReceived(new Uniform() {
public void handle(Request request, Response response) {
System.out.println(response.getStatus());
}
});
r.get();
Cheers,
ab

RE: Comprehensive example of authentication in RESTLet 2.0?
Hi all, Based on Thierrys reply, Ive updated the main security page in the user guide: http://wiki.restlet.org/docs_2.0/13-restlet/27-restlet/46-restlet.html That should help people getting started with Restlet 2.0 security API.

Hello, Thanks Garry for your mail. Just a few words about the security model in the Restlet framework. The Restlet framework has set up its own model (see here [0], [1]) based on some properties of the ClientInfo class: user and roles. This model gets along with ones that are based on principals that are closer or are based on JAAS. These models are distinct, and some bridges are required in some situations in case you want to use JAAS. The security model tries to distinguish the authentication and authorization aspects. The authentication steps relies on a dedicated filter which is a subclass of Authenticator (e.g. ChallengeAuthenticator, or your own) which verifies the credentials stored in the request (challengeResponse attribute) thanks to a Verifier (e.g. a SecretVerifier), Then, the Enroler (if any) is called in order to set the list of roles of the user. Once the credentials have been authenticated and the User and Roles have been set by the Authenticator/Verifier/Enroler, then the request is ready to be routed to the right resource. If the request is not authenticated, a Unauthorized (401) response is sent back, by default. According to your policy, some parts of the hierarchy of resource are only authorized to some kinds of people. This is the role of the Authorizer filter. In the sample code attached to this mail, I've implemented a RoleAuthorizer filter, that checks according to a set of autorized roles. You will see that the URIs hierarchy is splitted in two parts, each of them is protected by itw own instance of RoleAuthorizer. If a request is not authorized, a Forbidden (403) response is sent back, by default. Of course, you can customize each part: Authenticator, Verifier, Enroler, Authorizer. Regarding the Authenticator helper, this piece of code is used to handle the conversion of header values (of the protocol, e.g. HTTP) with the Restlet API model (Request/Response) in one direction, or both for a certain type of Authentication challenge scheme. At this time, the following schemes are supported: - HTTP_BASIC (client and server) with the core module - HTTP_DIGEST (client and server) with the crypto extension - Amazon S3, shared_key and shared_key_lite (client) with the crypto extension - SMTP (client) with the core module Best regards, Thierry Boileau [0] http://wiki.restlet.org/developers/172-restlet/212-restlet.html#dsy212-restl et_authenticationModel [1] http://wiki.restlet.org/developers/172-restlet/212-restlet.html#dsy212-restl et_authorizationModel Hi Drew, I can't give a comprehensive example but I just built something along these lines recently and actually found the main building blocks to be quite straightforward. I have a number of routes configured in my application, the first object in each is a custom class that extends org.restlet.security.Authenticator. That class has an authenticate method that receives the request and response objects and returns a boolean result -- though you also need set the status code on the response if it's a non 200-code situation. Within that method I check the custom values of the ChallengeResponse object that my AuthenticationHelper populates (see below) to make coarse authentication decisions. The next objects in my routes are then different subclasses of org.restlet.security.Authorizer that have an authorize method analogous to the authenticate method in the Authenticator. By this mechanism I have logic that has parsed the header into the user credentials, made a decision if this is a valid user and decided if they can use the resource before the resource is ever touched. Re the AuthenticationHelper, I was initially confused by this but for me it was easier than I expected. I wrote a subclass of org.restlet.engine.security.AuthenticatorHelper and overrode the parseResponse method. This method receives the raw bytes from the Authorization header in the request and its in this method that I take this and use it to populate the ChallengeResponse object used by the authenticator. So this is where you could do your database lookups to convert the raw auth data into fields on the ChallengeResponse object that the Authenticator will then use for its authentication decisions. AuthenticationHelper has a bunch of other methods depending on whether or not you've
How to write an Universal redirector
Hello everybody,
Could please anyone help me to write a universal redirector to match all
requests and to redirected them to a remote host?
Example:
Start: /redirect/RESTfulServices/resources/customers/pkey/2176172632
Finish:
http://192.168.100.1:8080/RESTfulServices/resources/customers/pkey/2176172632
GWT Client side:
ClientResource r = new
ClientResource(/redirect/RESTfulServices/resources/customers/pkey/2176172632);
Server side class TestRestletApplication extends Application (my web.xml was
changed to forward all /redirect/* requests to TestRestletApplication)
Router router = new Router(getContext());
router.attach(/RESTfulServices, new MyRedirector(getContext(), null)); //
-- this is wrong
and MyRedirector class:
public class MyRedirector extends Redirector {
public MyRedirector(Context context, String targetTemplate) {
// By default, the mode is MODE_CLIENT_DISPATCHER
super(context, targetTemplate);
}
@Override
protected Reference getTargetRef(Request request, Response response) {
Reference ref = request.getResourceRef();
ref.setHostDomain(192.168.100.1);
ref.setHostPort(8080);
// -- here is missing something
return ref;
}
}
Thank you for helping me.
