Re: Client Custom Header
Hi Stephan, Thank you for the response. I've implemented a filter and created one while setting the "next" property to be my client but I am not getting any calls to the beforeHandle function. My code looks like the following. class MyFilter extends Filter { public MyFilter() { this(null); public MyFilter(Context context) { this(context, null); } public MyFilter(Context context, Restlet next) { super(context, next); } public int beforeHandle(Request request, Response response) { System.out.println("HIT!"); return CONTINUE; } } And my Spring configuration looks like this... What am I missing? Thanks again. Jean-Philippe On Sat, May 1, 2010 at 3:49 AM, Stephan Koops wrote: > Hi Jean, > > the access is on both sides the same.

304 responses cause WARN logging
We recently updated to the newest RC (actually to revision 6570 of trunk), and now every single 304 response our server returns causes a WARN-level message to appear in the logs, like this: WARNING: Responses with a 304 (Not modified) status can't have an entity. Only adding entity headers for resource "http://localhost:8080/some/path/here/";. This doesn't seem desirable. This message is generated in the ServerAdapter.commit() method, if the status us 304 and isEntityAvailable() returns true. This implies it is incorrect for an representation at this stage (having gone through condition request handling) to be available. One change from 3 weeks ago that I found looking at SVN commits was a change to EmptyRepresentation.java which makes it "available", instead of unavailable. (It now passes 'true' instead of 'false' to setAvailable() in its constructor). This seems like a pretty significant change, especially given that there isn't much documentation for how the EmptyRepresenation is supposed to behave. In fact, it was our impression that the only way for us to return any entity metadata during a 304 was in fact to use a subclass of EmptyRepresentation. (Although I also noticed a current restlet issue which claims that this metadata is not, in fact, being actually sent!) So now, since an EmptyRepresentation is "available", the ServerAdapter is WARNing about a 304 with a, entity. However, I don't think the problem is just with EmptyRepresentation, something else must have changed, maybe in the conditional request handling, because we have other resources which have no special code in them at all, but which happen to publish an eTag in the representation subclass, and which therefor sometimes cause a 304 when requested, and we also see this warning showing up now for these requests. 1) what should the state of a representation be after conditional request handling? 2) how is the EmptyRepresentation supposed to be used? 3) Why is there a warning during a 304 response with an entity? thanks, -Dave Fogel -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2602172

RE: Re: SSL modifications since 2.0 RC 1 ?
Hi Bruno, You certainly put a lot of effort into that ! I have to admit that some of it went over my head - you obviously are a bit of an expert on the matter, which I'm not. If I understand you properly, the problem isn't Restlet, Safari, or even Java specific - it's a generic flaw (?) in client certificates management ? Which means that in my very specific, very selfish case, I should disable client certificate requests to make the problem go away. Which also means getting rid of the Simple connector, since this is hardcoded and can't be modified. Is that a fair summary, or did I misunderstand you even more badly than I thought ?

create inbound root override problem
Hello, I just downloaded restlet for gwt. I am attempting to integrate it into an existing gwt application. I am attempting to bring the test application into my project to ensure its configured properly. I get a sole compiler error saying that the createInboudRoot() method must override a supertype method. So it appears the version of Application.class I am using does not have this method which I find very strange. Why would this like that and how can I fix it? I am uing Maven to manage my dependencies and currently use org.restlet.gwt artifact id org.restlet. I suspect this may be the problem Thanks -- View this message in context: http://restlet-discuss.1400322.n2.nabble.com/create-inbound-root-override-problem-tp4956547p4956547.html Sent from the Restlet Discuss mailing list archive at Nabble.com. -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2594488
RE: Re: Proxying with Redirector with Restlet 1.1.1
Hey Rob, How can we avoid this 'lock up' situation your saying. I'm doing proxying too and I believe I'm encountering that issue. Here's a sample code to better explain. public static void main(String[] args) throws Exception { Component component = new Component(); component.getServers().add(Protocol.HTTP, 8182); component.getClients().add( Protocol.HTTP ); component.getDefaultHost().attach(new Redirector(null, "http://localhost:80{rr}";)); component.start(); } I'm using Restlet 2.0 RC 3. Ok here's my concern. Basically I want some request to redirect to a certain server: 1)On my first request (http://localhost:80/items/item), everything works as expected. 2) I shutdown the server running at localhost:80 3) Try to request again at the same resource (http://localhost:80/items/item) and the 'lock up' begins. Can anyone explain to me what's going on? What am I missing?

Beginner feedback
Hi! Recently I dedicated a couple of hours to learn about restlet (2.0-RC3). Maybe it is too little time, but I think my feedback may be important for restlet improvement. I've used as a documentation this link: http://www.restlet.org/documentation/2.0/firstSteps It is well documented. Unfortunately, I had some troubles in running the example. I have downloaded the distribution, created an eclipse project. The first problem was to set up the classpath of the project. There a dozen of dependencies. I didn't know which of them to add to the classpath. This is where maven would be useful. I use maven for all my projects and find it very easy to get started with other open source project. All you have to do, is to run mvn eclipse:eclipse and maven takes care about all project dependencies. It would be very useful for restelet adoption to 'mavenize' the project. Also, it could be useful to have a archetype - to generate a template of the project ready to run. The next problem, was to start the hello world example. I would expect to add the minimum dependencies to make it work. It seems very strange that hello world requires more than 10 dependencies to work (even java mail, grizzly, etc).. It seems a little bit strange, but maybe there is a reason. I like the way restlet is implemented, I would like to understand it better and use it when I'll have an opportunity. My purpose is not to criticize, but to help improve restlet. Thank you for your work!

Nested Routing problem
Hi, I have been trying to modify one of the example in the restlet.org site (http://wiki.restlet.org/docs_2.0/13-restlet/27-restlet/46-restlet.html - the security sample at the bottom of page). I am using restlet 2 RC3 (from April 23 I think). Here is my problem. I have the following routes: / --> show me a welcome page /staff --> ask for login then show me AResource /staff/{item-id} --> DOES NOT WORK /staff/{item-id}/pdf --> DOES NOT WORK /admin --> ask for login or refuses if I am a staff (so its good). My question is simply: what is wrong with my routes? (see below) So here is the code for those routes: public class App extends Application { @Override public Restlet createInboundRoot(){ Router root = new Router(getContext()); Router pub = new Router(getContext()); Router admin = new Router(getContext()); ChallengeAuthenticator guard = new ChallengeAuthenticator(getContext(), ChallengeScheme.HTTP_BASIC, "my realm"); guard.setVerifier(new UserVerifier()); guard.setEnroler(new UserEnroler()); guard.setNext(root); RoleAuthorizer ra = new RoleAuthorizer(); ra.getAuthorizedRoles().add(UserEnroler.PUBLISHER); RoleAuthorizer raa = new RoleAuthorizer(); raa.getAuthorizedRoles().add (UserEnroler.ADMINISTRATOR); root.attach("", PublicResource.class); root.attach("/staff", ra); root.attach("/admin", raa); ra.setNext(pub); raa.setNext(admin); pub.attach("", AResource.class); //** FOLLOWING TWO ROUTES DOES NOT WORK!!? pub.attach("/{item-id}", ItemResource.class); pub.attach("/{item-id}/pdf", PdfResource.class); admin.attach("", AResource.class); admin.attach("/test", AResource.class); return guard; Few Note: 1. I tested my resources classes to make sure they work. 2. I tried several "variations" of routes but nothing worked. 3. What I am trying to do, ultimately, is to have: / --> public page /staff --> staff protected resources /admin --> admin protected resources /staff/{item-id}/... staff protected resources /admin/{something}/... admin protected resources Can anyone help? What is wrong with my routes? Thank you in advance. Jocelyn BTW: I bought the book (actually our office) and I was wondering if anyone know when chapter 6 is coming out - because I think it might help me understanding these routes pattern? -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2597040

IRQ when a problem occurs?
Hello, Zfs is fine, and raidz too :) The goal of redundancy is not to loose data when a disk or more crash. But I've only seen a means to know if there is a disk corruption or disk lost , ie polling through the "zpool status" command. I would like to know if it exists a means to be notified through a interruption or a callback function, ie privileging push instead of pull? It is quite weird if it doesn't exist, that we need to do polling which is not a real time mechanism for high critical applications for instance. best regards Xavier -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2598691

Nested Routing Problem
First, I must apologies as I couldn't not reply to my previous post (I couldn't find any 'reply' link for some reason; probably because it wasn't approved by moderator yet). Anyway, this post is to show the solution to my problem and perhaps show a bug. The code I showed previously was (shortened for readability): Router root = new Router(getContext()); Router pub = new Router(getContext()); ChallengeAuthenticator guard = new ChallengeAuthenticator(getContext(), ChallengeScheme.HTTP_BASIC, "my realm"); guard.setVerifier(new UserVerifier()); guard.setEnroler(new UserEnroler()); guard.setNext(root); RoleAuthorizer ra = new RoleAuthorizer(); ra.getAuthorizedRoles().add(UserEnroler.PUBLISHER); root.attach("", PublicResource.class); root.attach("/staff", ra); ra.setNext(pub); pub.attach("", AResource.class); pub.attach("/{item-id}", ItemResource.class); pub.attach("/{item-id}/pdf", PdfResource.class); return guard; The above give the following result: /staff --> WORKS /staff/123 --> DOES NOT WORK /staff/123/pdf --> DOES NOT WORK How to fix this? Can you spot the differences? Here is the code that works: Router root = new Router(getContext()); Router pub = new Router(getContext()); ChallengeAuthenticator guard = new ChallengeAuthenticator(getContext(), ChallengeScheme.HTTP_BASIC, "my realm"); guard.setVerifier(new UserVerifier()); guard.setEnroler(new UserEnroler()); guard.setNext(root); RoleAuthorizer ra = new RoleAuthorizer(); ra.getAuthorizedRoles().add(UserEnroler.PUBLISHER); ra.setNext(pub); root.attach("", PublicResource.class); root.attach("/staff", ra); pub.attach("", AResource.class); pub.attach("/{item-id}", ItemResource.class); pub.attach("/{item-id}/pdf", PdfResource.class); return guard; All I did is to move "ra.setnext(pub);" three lines up. So for some reason if we attach a RoleAuthorizer before we use the setNext(...) method, it does not work. Is this a bug?

How to use Redirector with authentication?
Hi everyone, I am using the Redirector-class to proxy client requests (let's call it "client A") from server A to server B (i.e. MODE_SERVER_OUTBOUND): client A <=> server A <=> server B Now I want to guard access to the resources of server B with (digest) authentication. So I added the necessary guard to server B. Obviously, now users of client A have to enter a username and password. But I want the Redirector to "take care of this". I.e. I want to provide the username and password to the Redirector of server A so that client B does not require a username and password. How should I go about this? Do I need to create my own implementation of Redirector? Thanks for taking the time! BTW I am using restlet 2 RC3.
