Re: How to access user:password in servlet
Hello Macel, from what I see in the code, these data are not taken into account by HTTP. After having a look at the HTTP and URI specifications, it appears that HTTP relies on the definition of the host term ([1] and [2]) as specified in the URI spec ([3]) which does not take into account the userinfo part (4)... That can look quite odd. Anyway, passing user name and password in the userinfo subcomponent is clearly not recommended in the URI spec. Could you tell us more about your needs? best regards, Thierry Boileau [1] http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.2.1 [2] http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.2.2 [3] http://tools.ietf.org/html/rfc3986#section-3.2.2 [4] http://tools.ietf.org/html/rfc3986#section-3.2.1 Hi, I want to transfer user and password credentials: var loginName = jack; var password = 1122; var xhr = new XMLHttpRequest(); xhr.open(GET, link, async, loginName, password); In firebug I can see the URL send: jack:1...@localhost but I have found no way to access it in my restlet servlet (I have tried POST and GET).

Re: Expires Header and Conditional GET with status Not Modified
Hello, I think the client can stil send a conditional request according to its knowledge of the remote representation (its expiration time). If the server estimates that the representation needs to be refreshed, then it sends its back to the client. Otherwise, a 304 response is sent. best regards, Thierry Boileau I have written a Restlet Web Service and a (Restlet) Client and my own Cache solution on the client. The server is very simple, only example code from restlet.org My client does a GET for a resource, the server sends back a Representation and the Expires Header is set. My client use the Representation from the Cache for a specific time because of the Expires Header. Fine :) Later (after the Expires Timestamp) the client does a Conditional GET for the resource in order to see if the resource was changed. I see in Wireshark the If-Modified-Since header. Fine :) I can set the status on the server to Status.REDIRECTION_NOT_MODIFIED (304) for the response. I do not have to send back the respresentation. I say only, that it is valid. Fine :) But now the client doesn't know how long he can use his representation. After a Conditional GET i want to say the client, that his representation should be used for a specific time again, because it is valid. The Client should use the representation from his cache for a specific time and after that he should do a Conditional GET again. This is why i want to set the Expires Header after a Conditional GET. I could not set the Expires Header on the server, because this is only possible if i use a Representation for the Response. (If i want to send back a representation with REDIRECTION_NOT_MODIFIED, the Expires Header is not set in the restlet server (i see it in Wireshark), but it works if i do a normal GET. I tried to set the header via getAttributes() but after that a warning appeared, that i have to set the Expires Header via the restlet method (setExpirationDate()). I can set my own Header ExpiresWorkaround and it works, but i can not set the Expires Header. What should i do? (or is it wrong to set the Expires Header after a conditional GET, but then what should i do to get the above behaviour?) Thank you very much. -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=2423065 -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=2423251
Re: Newbie question about passing JSON object in a get request
Hi,
I also add that this sounds quite odd to send an object in the URI.
If you intend to use a GET method in order to not get the state of a
resource, you're surely missing something and going on a wrong way.
Best regards,
Thierry Boileau
If you're passing the JSON object as part of the URL it must be URL encoded.

Re: URI pattern handling
Hello Vlatko,
you can have a look at this page of the wiki [1] (for restlet 2.0),
especially the paragraph Matching of template variables.
It allows you define variables in the URI pattern that catch al kinds
of characters. By doing so you can define two kinds of routes:
/channels/{subscriptionPath}/subscriptions
/channels/{channel}
where channel and subscriptionPath are of type TYPE_ALL.
You may also have to configure the routing of the router (using the
first match mode), in order that the subscriptions resources are not
being kept by the catch-all pattern /channels/{channel}.
Best regards,
Thierry Boileau
[1] http://wiki.restlet.org/docs_2.0/143-restlet.html
I am implementing a RESTful publish subscribe protocol using Restlet. For
this purpose, anything under the pattern /channels should be considered as a
channel. For example:
/channels/building
/channels/building/floor1/room101
are both channels.
However, I would like to capture the pattern subscriptions under each channel
as a different Restlet resource:
/channels/building/subscriptions
/channels/building/floor1/room101/subscriptions
Any easy hint to achieve this in the most convenient way?
Thanks!
Vlatko

Setting Http Authorization header (part 2)
Hello Jerome and all Restlet fans!
I have spent my last 2 days trying to set the authorization header to a
certain value, using the restlet gwt api. However, I was unsuccessful, so I
started looking at the source code. You specifically said in the previous
message that an authorization header is automatically created for you when
you specify a ChallengeResponse object (also mentioned in wiki), but the
only code that actually does something with the ChallengeResponse object is
located in GwtHttpClientHelper lines 86-92:
if (request.getChallengeResponse() != null) {
result.getRequestBuilder().setUser(
request.getChallengeResponse().getIdentifier());
result.getRequestBuilder().setPassword(
String.valueOf(request.getChallengeResponse()
.getSecret()));
}
I have tried all kind of value combinations, but none showed the
Authorization header in Firebug. WHAT AM I MISSING here? PS: I don't need
a password set here, just a association between Authorization - Id in
headers map
Thanks, Alex

Re: How to access user:password in servlet

RE: Default routing mode change
Hi all,
Thanks for the valuable design feed-back. This indirectly relates to the
lack of usage of interfaces in the Restlet API and the pros/cons of this
design choice. I think this is important to keep those concerns in mind and
reevaluate them in the next major API version (3.0). Ive entered a new
task:
Reconsider usage of enumerations

Regarding the enums, we did consider them in several places but they
prevent
addition of new constants by the framework or by the developer,
especially
without breaking existing code.
Framework users wouldn't be able to add RouterMatchMode values (but see
below), but framework developers most certainly could. The enum facility was
designed so that changes to an enum type would not break binary
compatibility. One of our key design goals in JSR 201 was to ensure that it
would be possible to add values to an enum without requiring recompilation
of existing clients of the enum type.
They also produce extra artifacts in the Javadocs cluttering them.
Compare the int constants in Router to any of the nested enums in the
standard library (e.g., java.Text.Normalizer.Form), and I think it's clear
that putting the values in a separate artifact is a *good* thing. It makes
the enclosing type easier to read, because you don't have to wade through a
lot of constants before getting to the point of the class.
Effective Java, 2nd edition, Item 30 has a passionate endorsement of enums
over int constants.
Regarding enums and extensibility, this pattern works quite well:
interface MatchMode;
enum RouterMatchMode implements MatchMode {
BEST,
CUSTOM,
FIRST,
LAST,
NEXT,
RANDOM,
;
}
void Router::setDefaultMatchingMode(MatchMode mode);
Then a developer wanting to extend the match mode need only implement
the marker interface MatchMode on their new enum and they are
interchangable with those provided by the library. This implementation
style also makes it easier to extend the match modes because you don't
have to sit around thinking and double checking, now should my new
mode be index 5 or is that used by one in the lib already?
For more about this approach, see EJ2ed, Item 34: Emulate extensible enums
with interfaces.
This could be a huge win for Restlet.

The setIndent is not working because of this.

Best regards, Thierry Boileau Hi Dustin, 303 (see other) says, that the result is at the given location, and you have to get it with GET. So the behaviour is right. Use 301 (Moved Permanently) or 307 (Temporary redirect). See http://en.wikipedia.org/wiki/List_of_HTTP_status_codes#3xx_Redirection best regards Stephan Dustin N.

When I make POST calls to the Resource now, the log records it as a POST call, but my @Get method is being called instead. Does the redirectSeeOther() get cached somewhere or something? Normally I'd see a POST followed by a GET in the log. Is this a bug in the current 2.0 tree? The snapshot is doing the same thing. I've used wget and browser clients just to test this.

Client API for HTTP_DIGEST Auth in 2.0M6
I just migrated our client and server from 2.0m3 to 2.0M6. All of the changes were fairly easy to figure out except those related to adding ChallengeResponse for HTTP_DIGEST authentication. Our code was based upon the example in the user guide (which is still the example in today's version. We would build a form with the username, ri, nonce, realm, domain, algorithm and QOP from the result, and then calculate and add the d5 digest. The we call request.setCredentialComponents(form). Since setCredentialComponents() is gone, I tried to find an alternative example and was not able to find one, I tried calling the individual setters for each of the prpoerties that had been placed into the form, and then call Request.setChallengeResponse(). This compiles fine, but I get the following warning and the a 401 response.

RE: Re: Expires Header and Conditional GET with status Not Modified
Hello, yes, i know. The behaviour, you described, works fine, but I want more. I want to send back always a Expires Header! If the client does a Conditional GET, the server can send back a new representation with a new Expires header OR say Not Modified without Expires header, but if i do not send back the Expires Header, from now on the client doesn't use the cache and does always a Conditional GET. ONLY if i do a normal Get, then the representation is sent back with the Expires Header and then the client use the cache again until the Expiration time. I'm asking for a possibility to say Not Modified AND set the Expires Header, but i can't do that with Restlet. See below... Thank you. -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=2423504

Restlet 2.0 Best Practices
Hi, I am evaluating Restlet 2.0 vs. Spring 3.0 for a new project that is starting soon. I have done a lot of reading on the website and have written a couple of small programs with Restlet 2.0M6 to get the feel for it. I am looking to hear from people who have been using it into production about their configuration choices. 1) What connector are you using with Restlet in production? I very much like the idea of not having to run inside of a web container, but I am not sure from the list of available connectors which are the best for production, and what are the pros and con's of each connector. Any advice from the community on this is appreciated. 2) How are you dealing with Caching on the server side? The app I am working on does a lot of DB interactions and caching results between requests would improve performance. What caching solutions are people using with Restlets. 3) Are you finding that the Services / Data Access Layers in Standard Web Apps don’t apply in the Restlet World? Given that we are exposing resources and no longer exposing services and functionality, do you find that the need for Data Access Objects is gone? As i think about what the app will do, I keep noticing that it is easier to put the data access for a resource into the Restlet instead of making a Data Access Object. After all PUT, POST, and DELETE will do something to the persistent state of the resource and GET will just query it. Thoughts about this from the community are highly appreciated. 4) What does your Restlet production setup look like? Thanks Adib -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=2423544

Re: Dependency injection in Restlet 2.0 with Guice
I like how Harald extends Router to be injector-aware in order to avoid
requiring the explicit use of FinderFactory. In fact, I have been
experimenting with a Router extension that adds two more methods:
public TemplateRoute attach(String pathTemplate, Class? extends
ServerResource targetClass, Class? extends Annotation targetAnnotation) {
return attach(pathTemplate,
finderFactory.finderOf(Key.get(targetClass, targetAnnotation)));
}
public TemplateRoute attachDefault(Class? extends ServerResource
targetClass, Class? extends Annotation targetAnnotation) {
return attachDefault(finderFactory.finderOf(Key.get(targetClass,
targetAnnotation)));
}
This allows users to attach to resource classes qualified by an annotation,
which was the only thing that I felt was missing from Harald's GuiceRouter.
In order to smooth the way to JSR-330 integration, however, I think it would
be better to call this class QualifiedRouter and make it abstract, with
DI-framework-specific concrete subclasses. Ideally, construction could be
left to a factory class that would produce the correct concrete subclass
without having to mention it explicitly in the user code.
I'd like to see if it's possible to avoid having any extra machinery to deal
with servlets -- good support for servlets already comes with Guice and
Spring (and others I'm sure), so I'm working on a way to get the
injector-awareness passed in at the Application level so it doesn't leak
into Restlet wiring code. I wouldn't want to require a particular
structure for the linkage between Servlet and Restlet worlds.
Another topic: What about scopes? Servlets need scopes like request,
session, conversation, etc. Only the first of those makes any sense in
Restlet, but I'm having trouble imagining a strong need for it in practice,
given that Resources are fundamentally request-scoped. Does anyone have an
example of a need for binding in request scope that isn't trivially
satisfied by Restlet already?

Hi Tim and Harald,
The goal and main value is see is to ensure the maximum portability of a
Restlet Application from one deployment environment to another
(JSE/standalone, JEE, GAE, etc.).
GAE/J only provides HTTP listening through the Servlet API, so we have to
use our Servlet/Restlet adaptation layer. The default way is to leverage our
ServerServlet class from org.restlet.ext.servlet, but we also provide a
ServletAdapter class to manual adaptation.
It feels like both approaches should merge as soon as we configure the
inner of the Restlet Application with Guice. Same GuiceRouter and
GuiceFinder should be usable. I’ve added a comment on the related RFE:
“Add support for Guice”
http://restlet.tigris.org/issues/show_bug.cgi?id=546
Harald, would you be willing to contribute your code to the Guice extension
developed by Tim (with the help of Bruno Harbulot recently) and to
collaborate on creating the best Guice extension possible? The current
extension code is in Restlet Incubator but should find its official place in
the next Restlet 2.1 version.
Best regards,
Jerome Louvel

I thought that the GAE Edition of Restlet hid the servlet-ness and made
it possible to write standalone Restlet components that run in GAE. Is that
not the case?

Sorry for joining in the middle and not paying attention. Do you mean a scope annotation on the Resource class itself?

Re: Dependency injection in Restlet 2.0 with Guice
I meant whether you would find it useful/necessary to be able to bind
something in request scope and have it injected into your resources. An
artificial example off the top of my head:
// binding code
bind(Scratchpad.class).in(RequestScoped.class);
// Resource code
public class MyResource extends ServerResource {
@Inject MyResource(Scratchpad scratchPad) { ... }
...
}
It's not hard to accomplish if it doesn't have to be related to servlet
request scope, but I wonder if there's any point to it. I have a feeling I'm
forgetting something obvious.
