Timeout from ruby
Hello I had ruby on rails application, cosuming a restlet service in 1.2m1 version whith spring extension. Yesterday I upgraded to 2.0 and now I had a problem. If I make a petition using the web browser, it works fine, but when I do it from ruby, restlet gives the response after about 20 seconds. When I debugged it, I saw that when I make the call from ruby, first of all, It calls my resource's constructor, but it only goes into @get method after 20 seconds could I miss some configuration when I changed the version of restlet? regards -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=2835829

Describe Restlet services
Hi! I'd like to make a description of a restlet web service using 'wsdl' or something similar. I use Spring to attach all my resources to a SpringRouter, and I want to have a description of each one. is there any tool or any way to do it? thanks in advance -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=2431133
Request Session
Hi! I need some equivalent to the traditional HttpServletRequest.getSession(), because I'd have to insert some parameters into the session. org.restlet.Handler.getRequest() does'nt implement any getSession() method, so I need a way to do it. thanks -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=1170707
RE: Default Routes
did you check that requets to / are without parameters. If it's a
webservice and you use a browser, it can add some default paremeter, which
makes router to go to Special Resource.
I had a similar problem. check your log.

Ruben

RE: Default Routes
Sorry, had a typo in my original post. I tried:
router.attach(/, DefaultResource.class);
router.attach(/{year}, SpecialResource.class);
And all requests to / still go to the special resource. This seems like
a pretty standard configuration so I'm not sure why it's behaving this
way. Surely people use / all the time without problems, so am I
forgetting to set something else? Here's my entire code for createRoot():
Router router = new Router(getContext());
router.attach(/, DefaultResource.class);
router.attach(/{year}, SpecialResource.class);
return router;
Straight from the tutorial really. Ive also tried setting the
defaultMatchingMode to BEST, FIRST, and LAST, and all have the same
behavior.
As for your suggestion with making param match alpha_num, is there a way
to do this with restlets or would I just supply a regex? In the latter
case, how would the resource get the parameter since it's not named?
Thanks,
Mike

RE: Re: Attaching a org.restlet.Directory to SpringRouter.
Hello Santosh
you have to create a bean component, and use it to get the context
bean id=component class=
org.restlet.ext.spring.SpringComponent
property name=server ref=httpServer /
property name=defaultTarget ref=root /
property name=client
util:constant static-field=
org.restlet.data.Protocol.FILE /
/property
/bean
Don't forget to add Protocol.FILE to make the Directory work.

RE: Re: Attaching a org.restlet.Directory to SpringRouter.
I need the Context object to instantiate org.restlet.Directory(or its
subclass). Since component in my case is a servlet container(tomcat 6),
how/where do I get the context required for creating a directory?
Below is how my config looks-
WEB.XML:
servlet
servlet-nametest/servlet-name
servlet-classcom.noelios.restlet.ext.spring.RestletFrameworkServlet/servlet-class
load-on-startup1/load-on-startup
init-param
param-nametargetRestletBeanName/param-name
param-valuerestletRouter/param-value
/init-param
/servlet
servlet-mapping
servlet-nametest/servlet-name
url-pattern/*/url-pattern
/servlet-mapping
TEST-SERVLET.XML:
bean name=restletRouter
class=org.restlet.ext.spring.SpringRouter
property name=attachments
map
entry key=/users
bean class=org.restlet.ext.spring.SpringFinder
lookup-method name=createResource
bean=usersResource/
/bean
/entry
entry key=/users/{userID}
bean class=org.restlet.ext.spring.SpringFinder
lookup-method name=createResource
bean=userResource/
/bean
/entry
!- As suggested --
entry key=/images value-ref=directory/
/map
/property
bean id=directory class=...SpringDirectory
property name=componentref
local=component//property
/bean
/bean
In the code above, I do not to know to get the component object, since my
component is a sevlet container. What can be done?
Another thought is just to let webserver handle the static file requests
since it runs in tomcat. What you think?

Santosh

Re: Attaching a org.restlet.Directory to SpringRouter.
hi!
you have to attach a Directory:
bean id=root class=org.restlet.ext.spring.SpringRouter
property name=attachments
map
entry key=/test
bean class=
org.restlet.ext.spring.SpringFinder
lookup-method name=
createResource bean=testResource /
/bean
.
.
.
entry key=/images value-ref=directory
/
/map
/property
/bean
bean id=directory class=
informa.rest.spring.resources.SpringDirectory
property name=component
ref local=component/
!--util:property-path path=component.context
/--
/property
/bean
springDirectory have to implement a restlet's Directory

Attaching a org.restlet.Directory to SpringRouter.
Hello,
I am building a rest styled web app using restlet. Its integrated with
spring using RestletFrameworkServlet and routes requests using
SpringRouter. I am not able to attach a web directory to the router.
I think if I fill up ?? in the following code, i would be through, Can
some one help?
bean name=restletRouter
class=org.restlet.ext.spring.SpringRouter
property name=attachments
map
entry key=/images
??
/entry
entry key=/users
bean class=org.restlet.ext.spring.SpringFinder
lookup-method name=createResource
bean=usersResource/
/bean
/entry
entry key=/users/{userID}
bean class=org.restlet.ext.spring.SpringFinder
lookup-method name=createResource
bean=userResource/
/bean
/entry
/map
/property
/bean
So far I have been able to resolve all the issues just by reading the
community docs and emails :) and it has been a great support. Thank you
for all that.
Regards
Santosh

RE: Re: Browse a Directory from a web application inside jboss
hello!
I think it maybe caused by the component because I am not calling
component.start() method
I'm instantiating all components and resources from applicatonContext.xml
in Spring.
So, can you tell me a way to start my component from spring configuration?

RE: Re: Browse a Directory from a web application inside jboss
Hi Ruben,
It must be an issue with your component, here is a sample that works:
import org.restlet.Application;
import org.restlet.Component;
import org.restlet.Directory;
import org.restlet.Restlet;
import org.restlet.data.Protocol;
public class SpringDirectory extends Application {
@Override
public Restlet createRoot() {
return new Directory(getContext(), file:///c:/templates/);
}
public static void main(String[] args) throws Exception {
// Create a new Restlet component
final Component component = new Component();
component.getServers().add(Protocol.HTTP, 9876);
component.getDefaultHost().attach(new SpringDirectory());
component.start();
}
}
Best regards,
Jérôme Louvel

Hello,
I created the Directory in that way and it worked, but when I start my
server whows an error whith the first file:
GRAVE: The informa.rest.spring.resources.SpringDirectory class has no
Restlet defined to process calls. Maybe it wasn't properly started.
And it doesn't serve the file (error 500). If I refresh the page in the
browser it works.
public class SpringDirectory extends Application {
@Override
public Restlet createRoot() {
return new
Directory(getComponent().getContext().createChildContext(),
file:///c:/templates/);
}
I'm using 1.2-SNAPSHOT version.

This worked! Thanks for your time.

Hi Brian,
I've been adding the FILE client connector by creating a new component

Component component = new Component();
component.getClients().add(Protocol.FILE);
Directory directory = new
Directory(component.getContext().createChildContext(),
file:///c:/);
directory.setListingAllowed(true);
router.attach(/files, directory);
BTW the createChildContext() is in 1.1 so if you are using 1.0 just
remove it. There's also no need for the inner Application containing
the Directory.
