RE: resource scheme

I have to implement a multi-side RESTlet architecture to exchange message/resource between pharmacies and suppliers, and between suppliers and agents. It implicates thet in the suppliers side, there are resources POSTed or PUTted by booth pharmacies and agents and some resources destined to different pharmacies (fiscal invoices and similar) and other destined to different agents (order sheet and similar). It implicates thet each side cannot know the resources map and their structure in the other side (and cannot know the specific URI's). I think it's necessary to provide, before different clients GET, POST or PUT resources, an XML resource thet maps the structure of resources and over this map the client can generate the right URI's for the HTTP packets (WADL like). I'm aware this approach gets further from restlet architecture, but i don't succeed in imagining other solutions. It's all right or i'm crazy? If it's all right can you recommend me a particular structure for resources that is easier to manipulate? I can create a directory for each client and in each directory a tree of other directory for different resources using the name of directories as identifier... or there are other easier way to implement an manipulate better resource structure and map?

post in putUser Bookmark throws error
Hi,
I changed the Bookmark example
C:\restlet-1.1.4\src\org.restlet.example\org\restlet\example\book\rest\ch7\ApplicationTest.java
from Put to Post in putUser method as shown below:
public static void putUser(String userName, String password,
String fullName, String email) {
final Form form = new Form();
form.add(user[password], password);
form.add(user[full_name], fullName);
form.add(user[email], email);
final Response resp = new Client(Protocol.HTTP).post(
getUserUri(userName), form.getWebRepresentation());
System.out.println(resp.getStatus());
}
But now when I'm trying to add user, it throws error Internal Server Error
(500) - The server encountered an unexpected condition which prevented it from
fulfilling the request
I'm using stable restlet 1.1.7. Can you please tell me if its a bug or what I'm
doing wrong???
Thanks!

Re: Re: Google AppEngine and Restlet
Jérôme, As far as I understand, we can't reuse Restlet extensions made for org.restlet.* with org.restlet.gae.* classes, can we ? I have thought at a time that GAE would be a deployment option for our restlet applications. With the gae copy, we may not reuse an application as straitforward as I may have dreamed. I see Restlet extensible enough not to have to copy the full code base. Would that dream have been possible with 1.1 with the API and Engine separation ? Why should not we support this scenario ;) ?

Basically this means replacing the calls to new ServletLogger with Logger.getLogger e.g. in the ServletConverter constructor do something like... super(new Context(Logger.getLogger(ServletConverter.class.getName(; 2. Add org.freemarker.jar, org.restlet.jar, org.restlet.ext.servlet.jar and org.restlet.ext.freemarker.jar to the WEB-INF/lib of your google app project and add to the build path. 3. Follow usual setup for getting Restlet working in a Servlet environment. Folow the HelloWorld tutorial in the getting started docs - it should work fine locally (even without doing step 1. However, you'll need to replace these calls in order to get it to run in the real GAE) 4. Freemarker was a little more tricky, but not much. Create a freemarker configuration that uses the class template loader and put this in the Restlet Application context attributes. 5. Make sure your templates are somewhere on the class path. 6. Use the TemplateRepresentation along with your freemarker config from the context attributes 7. Make sure it works locally and upload to the app engine. Hopefully I'll get a chance to write this up properly over easter, but it wasn't too bad and looks promising so far.

RE: ServerResource is currently incompatible with OSGi
Hi Tal and Tim,
Thanks for the discussion. I have added a clearCache() method which is
invoked each time an application is stopped (there is no
Application#release() method). The minor issue with an application specific
cache is that resource classes could be shared by several applications.
I have also entered a RFE to keep track of the need for a more optimal
solution in the future:

Tim... you seem to be agreeing with me, then, that this does have something
to do with the Application, and you are also allowing for some redundancy in
calculation and memory use, so, again, why not just store it in the
Application's Context, where all this is taken care of automatically? I
think Jerome's first instinct here may have been the most straightforward.
Barring that, how about calling the clearCache in the Application's
release(), rather than stop()?

I wouldn't recommend RRWL for this.
Since it's harmless to recompute the AnnotationInfos, I think just having an

Application stops, say. It's worth a little redundant computation to avoid
having to deal with shared locks and liveness.

(ConcurrentHashMap is actually a very complicated and delicately tuned

There is currently no standard concurrent map with weak keys, although

it will actually happen.
Wrapping a WeakHashMap with synchronization is likely to be a performance

RE: Annotations and Restlet's future
Hi Tal,
Again, if there is no annotation declared on a ServerResource subclass,
there is nearly no cost for testing for the presence of those annotations.
Hence, it is not really necessary to call setAnnotated(false).
I don't want to add a new annotation for this. The fact that a class is a
resource is based on the class hierarchy (extending ServerResource), no need
to mark it with an additional annotation IMO.
Regarding other annotations, I don't want to go further on the JAX-RS road.
I really don't see the issue of calling a setter method to turn off
conditional processing, otherwise we risk using annotations as the
programming language.

Jerome Louvel

Objet : Re: Annotations and Restlet's future
Hi Jerome,
How about instead of calling setAnnotated(false), there would be an
annotation to turn annotation on? Since this doesn't seem like behavior
you'd want to turn on or off during the life of the resource instance, it
seems like it should be defined at the class level, not in the instance.
Makes sense?
Maybe something like this:
@Resource
class ArticleResource extends ServerResource {
@Get(txt)
...
}
The @Resource tag could also support parameters defining general
characteristics of the resource. Perhaps enabling conditional mode, etc.
Maybe it can even be a separate tag, such as @ConditionalResource.
What I'm hoping is that if this tag is not present, annotated mode would be
off, which is what I think should be the default.

Hi all,
I haven't fully digested all this feed-back, but it helps tremendously! Just
to clarify a few points:
*
Rob correctly guessed my thoughts, annotations should be a fully
optional feature
*
I like to have this feature turned on by default because it lowers
the barrier of entry for new users. For experienced Restlet developers, it's
easy enough to override the doInit() method and call
setAnnotated(false).
* Non-annotated resources shouldn't impose any significant performance
hit, even if the annotated flag is turned on (annotation detection is done
only once)
*
No additional annotation is expected in Restlet 1.2, we should stick
with the current 5 public annotations
*
Exceptions are no rethrown for annotated methods

Hello,
I thank you all to clear my mind about annotations.
Annotations are probably good to get started with a hello world or minimize
the amount of code you would write. But you lose some compilation checks and
moreover developing further more complex resources will require to
understand how it works (routing/switch logic) and which methods will not be
called because of the use of annotations. If I want to search for resources
class will I have to search for @Resource as well ? How far are we from
annotated Restlets ?
Would it be possible to have ServerResource free of annotation logic and an
AnnotatedServerResource subclass removing the need for isAnnotated ?

The basic steps I took were : 1. Modify ServletConverter and ServletContextAdapter as detailed below. Basically this means replacing the calls to new ServletLogger with Logger.getLogger e.g. in the ServletConverter constructor do something like... super(new Context(Logger.getLogger(ServletConverter.class.getName(; 2. Add org.freemarker.jar, org.restlet.jar, org.restlet.ext.servlet.jar and org.restlet.ext.freemarker.jar to the WEB-INF/lib of your google app project and add to the build path. 3. Follow usual setup for getting Restlet working in a Servlet environment. Folow the HelloWorld tutorial in the getting started docs - it should work fine locally (even without doing step 1. However, you'll need to replace these calls in order to get it to run in the real GAE) 4. Freemarker was a little more tricky, but not much. Create a freemarker configuration that uses the class template loader and put this in the Restlet Application context attributes. 5. Make sure your templates are somewhere on the class path. 6. Use the TemplateRepresentation along with your freemarker config from the context attributes 7. Make sure it works locally and upload to the app engine. Hopefully I'll get a chance to write this up properly over easter, but it wasn't too bad and looks promising so far.

RE: Managing a JPA/Hibernate session
Hi Matt, There has been a recent discussion on this topic in this list. Some changes were made in SVN trunk so that ConnectorService callback methods are systematically called after sending representations/responses. You basically have to provide a custom ConnectorService that intercepts those calls to update your EntityManager accordingly. Also, as this piece of code seems rather generic, there might be an opportunity to provide a specific Restlet extension for this... Feel free to contribute one or to enter a RFE.

Re: Restlet 1.2 M2, Simple, and HTTPS
Hi MattyJ, I've faced the same problem before using Restlet M1 and i discovered the cause that is i was using Grizzly connector, removing the latter and working with Simple solved my problem. However some of my friends who were facing the same prob, did the opposite to get over it (i.e. they used grizzly instead of simple). So i suggested you swap and test different connectors separately and observe if that solves it or not ... Wish this helps a lil' Hi there, The application I'm building uses the simpleframework.

RE: Re: Google AppEngine and Restlet
Hi Zsolt, Restlet/GWT should definitely work with GAE. From a GAE point of view, everything will look like compiled Javascript files served statically by your Restlet/GAE application. On the server-side, you can definitely use Restlet instead of GWT-RPC. The GwtShellServletWrapper is even included in the org.restlet.gae.jar file. http://www.restlet.org/documentation/snapshot/gae/org/restlet/util/GwtShellS ervletWrapper.html Let us know if you encounter any difficulty.

I am learning GEA and GWT and before I start to investigate, I would appreciate your feedback. Regard, Zsolt Hi Remi, As long as the extension only relies on GAE's white listed JRE classes, it will work without any modification (example: the FreeMarker extension). Your dream can come true already :-) In the recent version of org.restlet.gae.jar, the packages are the same as in org.restlet.jar so it should be easy to leverage Restlet extensions that are compatible with GAE. As a result, it should be possible to deploy existing Restlet applications in GAE without any modification, as long as their are compatible with GAE's environment of course.

Re: FreeMarker Template Loading
Jerome, Thanks, this works as expected with one exception. The getLastModified(Object templateSource) returns a NullPointerException all the time for me as the getModificationDate() from the Representation (templateSource) is always null. I overrode the class and that method and it works as expected. Should I make a ticket for this too or is this e-mail sufficient?

I am able to use this: getContext().getClientDispatcher().get(war:///freemarker-templates/ + templateName).getEntity(); and wrap it in a TemplateRepresentation, but my #include myHeader.ftl files within my templates no longer work as they're relative URLs.
