Re: ObjectRepresentation and String encoding
Hi Hannes,
I had a look at the issue and I don't see what's wrong. I was able to
send a serialized object from a client using UTF-8 to a server using
ISO-8859-1 without encoding issues.
Could you send us a reproductible test case, and send us also the trace
of the following code on both client and server side?
for (EntryObject, Object entry :
System.getProperties().entrySet()) {
System.out.print(entry.getKey());
System.out.print(=);
System.out.println(entry.getValue());
}
Best regards,
Thierry Boileau

Hi Jerome,
It looks like a bug but after looking at the code I don't see what we
are doing wrong as we have no control on encoding for Object
serialization.
Anyway, I've entered a bug report:
great, thanks!
If you could attach a reproducible test case (client+server code),
that would help us fix it more quickly. Also, could you add a comment
to the report indicating which client and server connectors you are
using?
Yes, I will do this during the next days.

Hi Kevin (Conaway),
I would like to have your thinking about a problem we are facing
with (see issue http://restlet.tigris.org/issues/show_bug.cgi?id=514).
I've a simple internal client that simply send several (POST, but
I don't think it is meaningful) requests (in my case, 1
requests) to the server which sets the status and doesn't send a
response entity or sends an entity with an unknown size (which
leads to chunk encoding).
In this case after the handling of several requests, the server
block when accepting a new incoming one.
I think that the required behaviour is the following : after
sending the headers, and because the connection is not persistent,
the server can close the connection.
At this time, the closing of connections relies on the fact that
there is an entity, with or without chunk encoding, with or
without persistent connection.
I notice that the fact there is no entity is not taken into
account. I notice also that when there is chunck encoding, the
ChunckedInputStream class does not close the underlying socket.
To my mind, the closing of the socket (on server side) relies
only on the fact that the connection is persistent or not.
So I would like to know if the following test in the
StreamServerCall#complete method could be sufficient:
if (!this.socket.isClosed()) {
this.socket.getOutputStream().flush();
this.socket.shutdownOutput();
if (!isKeepAlive()) {
this.socket.close();
}
}

If this is the case, I think we can remove it from our Maven repository which is simpler. best regards, Thierry Boileau Hello, I've just realised that the groupId values used by the build script (for Maven2 packaging) were actually those used by the original projects. For example, it creates POMs for groupId org.jsslutils, whereas I've used org.jsslutils for the official bundles I've produced for that project (to be published in the central repository). I'm a bit concerned this may conflict with the versions from the central repository when they are available. In the case of jsslutils (although version 0.5 isn't in the central repository yet), the POM generated by the Restlet build file removes some information, such as the location of the source, etc. Because the build script effectively repackages many libraries that may also be more officially packaged in the central Maven repository, I think the guidelines at [1] should be used, in particular the FAQ I have a patched version of the foo project developed at foo.com, what groupId should I use? (even if it's not strictly speaking patched). This could lead to things like: groupIdorg.restlet/groupId artifactIdorg.jsslutils-jsslutils/artifactId or some variants: groupIdorg.restlet.external/groupId artifactIdorg.jsslutils-jsslutils/artifactId ... groupIdorg.restlet/groupId artifactIdexternal-org.jsslutils-jsslutils/artifactId I'm not sure what's best.

Re: PUT method without body entity
Mail sent on the 08/22 and apparently lost. -- Hello Vincent, this question comes back now and then (see [1] and [2]). The current conclusion is that, as some other implementations, it has been decided to forbid empty entities for PUT requests inside Restlet according to a strict interpretation of the HTTP spec. Since the POST method has a more general meaning, empty entities are tolerable which explains the difference. Having said that, and since internet browsers don't support PUT requests, Restlet should provide ways to generate PUT-like requests. A step has been accomplished with the TunnelFilter (see [3] and [4]) which allows to fake a PUT with a POST. If you can't use POST but only GET requests, you seem to have a need that is not satisfied yet. You can achieve it with an additionnal filter that checks the query string and sets the entity of the PUT request. I've entered an RFE (http://restlet.tigris.org/issues/show_bug.cgi?id=575) for this point. I end with the fact that there is a huge drawback: it breaks the semantics of GET requests which is used for retrieval.

RESTlet returns an HTTP 400 status. Is it a strict behavior required by the RFC? I expected the same behavior as the handlePost() method: a log trace, then a call to storeRepresentation with a 'null' param. So, is it a bug of an HTTP feature? Regards,
Re: WADL howto?
Mail sent on the 08/22 and apparently lost. --- Hello John, 1) I tried deriving my Application from WadlApplication, called setAutoDescribed(true), and tested. I can get the WADL, but not using my /v1/* URI. If I use the /v1/* URI, I get a 404; I have to use just the /v1/ URI, I get a version of a WADL response, which includes all of my various Resources. This seems to contradict the documentation? oops, you're right, the javadocs reflected a former state of the implemented behaviour. I've updated it. Thanks for your report. Hi Ralf, Does the WADL extension support this (from my understanding it does) and are there any tutorials for it? It haven't found anything yet, besides the API, and to figure it out with from API alone is a litte tiresome ;) I used the wadl component in the other way (specify the wadl file, and let WadlComponent load my Resource subclasses); but in your case, i think you just have to inherit WadlApplication to register your WadlResource subclasses (with createRoot), and for each resource override the 'describe' method. Excerpt from the javadoc: This description can be customized by overriding the #describe() and #describeMethod(Method, MethodInfo) methods. Hope this help. I can't speak for Ralf, but I found that it does help, a lot. I thought I'd try this, too, but I'm still getting some odd results. Here are some of my observations, so far. 1) I tried deriving my Application from WadlApplication, called setAutoDescribed(true), and tested. I can get the WADL, but not using my /v1/* URI. If I use the /v1/* URI, I get a 404; I have to use just the /v1/ URI, I get a version of a WADL response, which includes all of my various Resources. This seems to contradict the documentation? 2) Next, I think there may be an interaction between WADL auto-generation and having a resource available at the root URI. I tried changing my root resource to derive from WadlResource, and my generated WADL became ONLY the description of the root resource itself, not the whole resource hierarchy as was the case previously. (This makes a certain amount of sense, because with a resource at my URI root, it's using the same URI that the WADL request is using. Probably ought to be document, though.) I changed my root resource so that it's subordinate, and it seems like that works.

Just have a look at the Javadocs, there is a match(String) method that you
can use. You might need to adjust the matching mode and the default variable

Re: Using the entity in a Filter
Mail sent on the 08/28 and apparently lost. --- Hello Jim, you can have a look at this issue: http://restlet.tigris.org/issues/show_bug.cgi?id=149 The idea was to support the content-md5 standard header and to allow users to manually check the digest value of a representation. Here is the list of the additions: - a Digest object in the org.restlet.data package that stores an algorithm and a value. - a "digest" property on a Representation that contains the checksum of the representation computed according to an algorithm. - a computeDigest(String) on a Representation that reads entirely the representation and computes the digested value - two checkDigest methods on a Representation that ... checks the current digest value with the computed one. - the API handles the mapping between the digest attribute of a representation (of the request or the response) and the "content-md5" header (the only supported by the HTTP RFC). As you may have noticed, there is no automatic way to check the digested value. The reason is that, as you point, there is a high cost and we were quite reluctant to "impose" that in a filter. The idea is to let you store the stream at your convenience and check the digested value when you want: in a filter, at the resource level. etc. best regards, Thierry Boileau Hi, I need to use the entity of a response to generate a digital signature in a filter before it is passed to the Router.

Re: GWT + Restlet examples?
Mail sent on the 09/10 and apparently lost. --- Hello Duong, what kind of problem are you experiencing with the creation of directories? best regards, Thierry Boileau I don't mean to throw a wet blanket on the GWT discussion, but my (limited) impression of GWT was that it was trying to abstract away the web, rather than embrace it. Rather than dealing with loosely coupled services, resources, and representations, it wraps everything into a nice tidy Java API that would be familiar to Swing and RPC service developers. I certainly think there's a good place for frameworks like these (just look at the popularity of GWT), but trying to adapt it to a REST world sounds like you're barking up the wrong tree. I'd love to hear other points of view, though. Justin Hi: I am exiting with both GWT and Restlet, but have not had time to look at Reslet-GWT API for client side. On the GWT front, the cited tutorial demonstrates a new Java overlay integration between Java and JavaScripts via JSONP. Last time, i looked at the Restlet there is org.restlet.ext.json_2.0 extension that i plan to dive into. I still have issue with creating directory resource using com.noelios.restlet.ext.servlet.ServerServlet in Tomcat 6. The directory resource work fine under Restlet component server. Please let me know if anyone has made it work under tomcat or glassfish v3. BTW, i think Restlet is exiting, so does GWT-1.5. Is there any example to show server-side Restlet JSON service, even better to integrate with GWT 1.5 JSONP using Java overlay? My strategy is to separate client-side and server-side services so my server is only 1 of many possible service sources for GWT mashup, where GWT application is compiled and served under directory resource of Restlet under a Servlet engine available at hosted sides such as GoDaddy. Is it a recommended practice? I can take criticism so please share your experience.

Hello Kenji,
I'm a little surprised by the fact that the Filter#afterHandle method
does not work as expected. What kind of filter are you suspecting to
fail?
Anyway, I send you a sample code containing 3 classes: an application,
a resource and a filter.
The application puts the filter as its own root restlet, thus the
afterHandle method of the filter is called after all methods.
Please feel free to detail your need, I may have missed something.

There seem to be some sort of conflict with creating Component and Application objects when using the new Spring integration classes. I want to use the default component and so I removed the following setting from my web.xml and spring bean config. context-param param-nameorg.restlet.component/param-name param-valuecomponent/param-value /context-param bean id="component" class="org.restlet.ext.spring.SpringComponent" ... bean However, in SpringServerServlet.java, line 134, the statement component = (Component) getWebApplicationContext().getBean(componentBeanName); will throw an IllegalArgumentException if componentBeanName is null or NoSuchBeanDefinitionException if the bean does not exist, ie no 'org.restlet.component' and 'component'. Null component is never returned and tested. The call to create the default component is never called. To avoid the exceptions I add the 'org.restlet.component' and 'component' init parameter settings. But this prevents the Application object to be created via the method getApplication() in ServerServlet.java, line 580. The call to isDefaultComponent() always returns false because I've added the 'org.restlet.component' context init parameter. This in turn makes the method getApplication() return null always. There is also a null SuppressWarnings annotation. Is there a way around this? Thanks.

Re: GWT + Restlet examples?
Hi Mark,
the TestServer is a very simple server-side application using only a
Restlet.
In this case, if you want to handle only, let's say, GET requests, you
have to test it by yourself and generate correctly the response in the
handle(request, Response) method.
I suggest you develop the server-side application with Resource. Here is
a pointer that will help you:
http://www.restlet.org/documentation/1.1/firstResource.
The list of allowed methods for a resource can be controlled via the
allow* methods and or the modifiable/readable properties.
You can see the javadocs for more details
(http://www.restlet.org/documentation/1.1/api/org/restlet/resource/Resource.html;).

Re: GWT + Restlet examples?
In a real application, it is usually better to write high-level Resources than Restlets, though wiring in a Restlet as in the Foo.zip example is often the briefest way to return an HTTP response. Have a look at this tutorial, if you haven't already: http://www.restlet.org/documentation/1.1/firstResource Resources are at a higher level of abstraction. A new instance of a Resource is created to handle each Request, which frees you from some thread safety concerns. Restlet instances are permanently wired in to your application, and can handle Requests from many threads, so they must be thread safe. By overriding methods like allowPost() to return true, the Resource signals what's allowed higher up the chain. Methods like represent() and acceptRepresentation() allow you to expose the representational details of your object, and let the Restlet API handle the rest of the connector infrastructure (magically coping with hard stuff like ETag assignment and dealing with conditional GETs in HTTP). There's no difference in server-side Restlet programming for a GWT client and a non-GWT client, so all the existing 1.1 documentation applies.

Env: jdk1.6 (U3), tomcat 6.0.14, linux CentOS (clone of RedHat enterprise). There are some hosting services that provide either Tomcat-6 or Glassfish v.3. I think simple integration with popular servlet engines to make GWT compiled file working as static client that use restlet JSON service as in your example (i have not looked into it yet) make restlet work seamlessly in both client and server side using OSGi as the Vision of Restlet. http://budhnet.com/ http://budhnet.com/muweb/#Home http://budhnet.com/muweb/#AccountingJobs are the way for Restlet and GWT working together. Please help and test for this very practical architect to take restlet to the mass production level, especially with GUICE DI of reslet resources (please post if someone has made it work under new restlet). Best Regards Duong BaTien DBGROUPS and BudhNet I'd love to hear other points of view, though. Justin Hi: I am exiting with both GWT and Restlet, but have not had time to look at Reslet-GWT API for client side. On the GWT front, the cited tutorial demonstrates a new Java overlay integration between Java and JavaScripts via JSONP. Last time, i looked at the Restlet there is org.restlet.ext.json_2.0 extension that i plan to dive into. I still have issue with creating directory resource using com.noelios.restlet.ext.servlet.ServerServlet in Tomcat 6. The directory resource work fine under Restlet component server. Please let me know if anyone has made it work under tomcat or glassfish v3. BTW, i think Restlet is exiting, so does GWT-1.5. Is there any example to show server-side Restlet JSON service, even better to integrate with GWT 1.5 JSONP using Java overlay? My strategy is to separate client-side and server-side services so my server is only 1 of many possible service sources for GWT mashup, where GWT application is compiled and served under directory resource of Restlet under a Servlet engine available at hosted sides such as GoDaddy. Is it a recommended practice? I can take criticism so please share your experience. Duong Batien DBGROUPS and BudhNet

Re: GWT + Restlet examples?
Thanks for this, Thierry! I have changed some names, made some more objects (a Component, Application, and Resource ...) and wrapped it up into an Eclipse project with Ant build script, hosted mode launcher, and a working server side, added tomcat's web.xml, embedded the Restlet jars, and made the file available on the Restlet wiki on the GWT documentation page. I also put some of the code snippets into the page directly. http://wiki.restlet.org/docs_1.1/g1/13-restlet/28-restlet/144-restlet.html This will have to hold us for a little bit until a bigger and better example comes along. But I hope that most people can just pop this into Eclipse and get past most of the configurational pain. - Rob On Thu, Sep 11, 2008 at 6:03 AM, Thierry Boileau [EMAIL PROTECTED] wrote: One part is developped with the gwt technology and aims at building a simple HTML page. It integrates also a simple AJAX call to the server part therefore it relies also on the org.rest.gwt.jar package which is the integration of both GWT and Restlet (client only) technologies. All sources and libraries (except GWT) are located in the gwt-Foo.zip file attached to this mail. It contains only one source file called Foo.java.
INFO in NRE SecurityUtils
I'm using 1.0, so this may already be fixed in 1.1, but a quick search of the list didn't turn up anything, so I thought I'd ask. I'm using Basic HTTP Auth, and I've implemented a subclass of Guard, wherein I've overridden doHandle(). I know that's not the recommended approach, but I don't think it's relevant to this question. I keep seeing entries in my logs that look like this: Sep 11, 2008 6:02:50 PM com.noelios.restlet.util.SecurityUtils parseResponse INFO: Basic HTTP authentication succeeded: identifier=avif. The thing is, this is even in cases where basic auth fails, in my Guard, wherein I call challenge(response). I think this log record is really just saying I was able to successfully parse the Authorization header into a ChallengeResponse object, which is good info, but: (A) it should be a FINE or FINER, not an INFO, and (B) the message is misleading. Does that make sense? Thanks, Avi -- Avi Flax » Lead Technologist » Partner » Arc90 » http://arc90.com
Restlet + Dojo?
Anyone using this combo? Any tips? Just wanted to give a shout out. I'm looking into using this combo, seems like a good fit. I would just use JSON services with Restlet resources.
Re: GWT + Restlet examples?
Thank you. In fact, that example made it to hardcopy and accompanied me to lunch twice this week. Good stuff. Mark On Sep 11, 2008, at 10:06 AM, Rob Heittman wrote: In a real application, it is usually better to write high-level Resources than Restlets, though wiring in a Restlet as in the Foo.zip example is often the briefest way to return an HTTP response. Have a look at this tutorial, if you haven't already: http://www.restlet.org/documentation/1.1/firstResource Resources are at a higher level of abstraction. A new instance of a Resource is created to handle each Request, which frees you from some thread safety concerns. Restlet instances are permanently wired in to your application, and can handle Requests from many threads, so they must be thread safe. By overriding methods like allowPost() to return true, the Resource signals what's allowed higher up the chain. Methods like represent() and acceptRepresentation() allow you to expose the representational details of your object, and let the Restlet API handle the rest of the connector infrastructure (magically coping with hard stuff like ETag assignment and dealing with conditional GETs in HTTP). There's no difference in server-side Restlet programming for a GWT client and a non-GWT client, so all the existing 1.1 documentation applies.

Re: How to hook end of POST
Hi Thierry,
Thank you for the sample codes.
I modifed the codes so they can show this problem.
You can see that Filter#afterHandle is called before
WriterRepresentation#write in the console.

Hello Kenji,
I'm a little surprised by the fact that the Filter#afterHandle method does
not work as expected. What kind of filter are you suspecting to fail?
Anyway, I send you a sample code containing 3 classes: an application, a
resource and a filter.
The application puts the filter as its own root restlet, thus the
afterHandle method of the filter is called after all methods.
Please feel free to detail your need, I may have missed something.
Best regards,
Thierry Boileau

Hi,
I'm trying to hook the end of POST calls, and I've tried these :
Filter#afterHandle
Handler#handleXxx
Application#handle
Works fine for GET requests, but for POST requests, these get called before
response data is sent to the browser.
Is there any way to hook the point when response data is sent?
Thanks,
Kenji Tayama
