In Restlet 1.2, SpringBeanRouter has been updated to pass the application context to the finders it creates, if an application context is available. It makes sense to use the same mechanism for SpringBeanFinder directly. New issue: http://restlet.tigris.org/issues/show_bug.cgi?id=751 > 2.

My suggestion would be to use SpringBeanRouter if you want Spring- managed resource beans, unless you need to map multiple routes to the same resource. A static map with refs (such as that used by SpringRouter) wouldn't work for spring-managed resources, since they need to be non-singletons. You could write your own map-based router that uses ApplicationContextAware (as you suggest) and attaches SpringBeanFinders for each bean name / URL pattern pattern pair. I don't think that modifying SpringRouter to achieve this is the right way to go -- it would make SpringRouter complex and branching in a way that isn't justified by the amount of code that would be shared between the variants. If you do write your own router, I'm sure Jerome would be willing to consider adding it to the spring extension. > Well sorry for lot of text probabaly not well written :) > Will be appreciate for any response. > > Maybe i havent found related open issues in issue tracking > or in case you need any help on better spring integration or idea i > will > be glad to help Rhett -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=1263762
RE: GWT Restlet Callback
I figured out how to do this using the following and ran into another api problem that was easy to fix with source. I posted an earlier message about a problem I was having doing incremental updates when developing with GWT that are a problem with innerclasses. For some reason doing incremental code updates for a class where you are changing code logic but not altering the class schema is a problem with inner classes. When developing with GWT you want to minimize the amount of build/deploy when you are working on code. Incremental compiles is very important for productivity. Basically, I want the class that is calling a REST method to be the callback listener. A couple problems. The first is being able to stuff a unique name in the request so that when you get the callback to can get the name from the original calling method and execute the appropriate callback logic. When you make multiple REST calls in a single class sharing one callback method you need this. I solved this by adding this to my RestHelper class request.getAttributes().put(CALLBACK_ID, callbackID); to store a unique string based on the calling method. Then in the onEvent method I have String id = (String)request.getAttributes().get(RESTHelper.CALLBACK_ID); which allows me to handle the response with the proper code. Then next major problem is that Callback in Rest is defined as an Abstract class when it should be an interface. I pulled the source into my project and changed to an interface and added another abstract class called RestCallback that implements the interface so that you can still do inner class version of a callback and override the onEvent method. The only core Rest code that appears to need a Callback class to override is HttpClientConverter. I have solved my problem for the short term but in the event you have any code refactoring coming up it would be nice to see Callback become an interface or leave Callback as an abstract class that extends CallbackInterface and change all the calling methods to use CallbackInterface. This way it won't break code for those using the library Thanks Scooter Willis -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=1263101
GWT Restlet Callback
I wanted to say a quick thanks for an excellent API/toolkit. I had no trouble getting XML data via REST calls integrated into our GWT application. Not a big fan of innerclasses but they are convenient given the examples of defining the callback class for a particular REST call. The problem I am having is doing incremental updates in debug mode where the inner classes create more than one class file to be updated which 9 times out of 10 causes the incremental update to fail. This really makes coding slow going because of the time it takes to tweak code and start a new debug instance with GWT. I am looking for a way to set an unique ID in either the client call that I can then retrieve from the request or response object. This way I would make the calling class a Callback listener and can then process multiple call backs in one method and avoid the inner class problem of doing incremental updates. I could append something to the URL and then parse but my assumption is that an easier/cleaner way already exists since you can internally map a Rest call to a particular callback class to use. If you have an easy way to do this can you email a response to hwil...@scripps.edu? Thanks Scooter Willis -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=1262605

Re: Embedding hierarchy of differing depths in URIs
Hello,
it is more a matter of URI design that compliance to REST principles. If
there is a real hierarchy, well, it seems correct.
Do all URIs identify the same kind of resource, the same concept?
If so, you can proceed as follow:
Route route = router.attach("/{hierarchy}/{data}", );
Template template = route.getTemplate();
template.getVariables().put("hierarchy", new Variable(Variable.TYPE_ALL));
In this case, the "hierarchy" variable gets the whole hierarchy and let
the "data" variable get the last segment (variable catch segments by
default ).
Then, in your Restlet or Resource, you can have access to the content of
"hierarchy" and "data" variables :
System.out.println("hierarchy " +
request.getAttributes().get("hierarchy"));
System.out.println("data " +
request.getAttributes().get("data"));
I hope this will help you.
Best regards,
Thierry Boileau

RE: POST/PUT requests take more than 2 seconds
Hi again, I'm working on this project again (after more than one month of interruption). I'm now using: - Restlet 1.1.3 - curl 7.16.3 - RESTClient 2.3 - the same sample code as Avi (see link to his message below) Here are the results with curl: > time curl -X POST -d @test.txt http://localhost:3000/ Test real0m0.008s user0m0.003s sys 0m0.003s > time curl -0 -X POST -d @test.txt http://localhost:3000/ Test real0m0.009s user0m0.004s sys 0m0.003s So, no problem with curl, as previously mentioned. Now, with RESTClient (HTTP 1.0): "Response received in 7 ms". With RESTClient (HTTP 1.1): "Response received in 2003 ms". That was my problem. It's perfectly reproducible. RESTClient uses HTTP 1.1 by default, which I previously hadn't realized. I don't know why curl doesn't have the same problem, though. At that point, I don't know if it's a bug in RESTClient or in Restlet. What do you think?

Re: Transformer -- dynamic use
Hi,
by the way, you can also define a unique Resource for the main reason
that there is no need to make a distinction based on the format. Both
HTML and XML representations vehicle the same data and represent the
same concept, ie resource.
That is to say :
* Have a single resource
router.attach("/{device}/filelist", FilelistResource.class);
* This resource defines the supported formats, for example in the
constructor:
getVariants().add(new Variant(MediaType.TEXT_XML);
getVariants().add(new Variant(MediaType.TEXT_HTML);
* Then, just implements the method FilelistResource#represent(Variant
variant) where variant is one of the defined variant, and is computed
according to client's preferences.
You can have a look at the tutorial =>
http://www.restlet.org/documentation/1.1/firstResource
And at the tunnel service for several ways to update client's
preferences =>
http://www.restlet.org/documentation/1.1/api/org/restlet/service/TunnelService.html

Re: Transformer -- dynamic use
Hi,
could you try with another kind of representations (not
DomRepresentation) such as FileRepresentation or StringRepresentation
for both XML and XSLT files?
Representation xmlRepresentation = new
FileRepresentation("/path/to/file.xml", MediaType.TEXT_XML));
Representation xsltRepresentation = new
FileRepresentation("/path/to/file.xsl", MediaType.TEXT_XML));
Representation htmlRepresentation = new
TransformRepresentation(xmlRepresentation, xsltRepresentation);
htmlRepresentation.write(System.out);
