[GroovyRestlet] GroovyRestlet is hosted as a Groovy Module
GroovyRestlet is a simple and ease of use Groovy DSL for constructing
Restlet application.
Main features of GroovyRestlet:
* Simple Groovy DSL syntax and shortcuts for easily constructing
Restlet application
* Better integration with Spring framework
A simple example of GroovyRestlet DSL:
builder.component{
current.servers.add(protocol.HTTP, 8182)
application(uri:){
router{
def guard = guard(uri:/docs,
scheme:challengeScheme.HTTP_BASIC,
realm:Restlet Tutorials)
guard.secrets.put(scott, tiger.toCharArray())
guard.next = directory(root:, autoAttach:false)
restlet(uri:/users/{user}, handle:{req,resp-
resp.setEntity(Account of user
\${req.attributes.get('user')}\,
mediaType.TEXT_PLAIN)
})
restlet(uri:/users/{user}/orders, handle:{req, resp-
resp.setEntity(Orders or user
\${req.attributes.get('user')}\,
mediaType.TEXT_PLAIN)
})
restlet(uri:/users/{user}/orders/{order}, handle:{req, resp-
def attrs = req.attributes
def message = Order \${attrs.get('order')}\ for
User \${attrs.get('user')}\
resp.setEntity(message, mediaType.TEXT_PLAIN)
})
}
}
}.start()

Re: servlet mapping question
Hello all, some words to complete Stephan's answer. Let's say that the name of the WAR file is myWar. 1- Let's say that the RestletServlet is configured like this : url-pattern/testServlet/*/url-pattern and the application as follow: router.attach(/testResource,HelloWorldResource.class); then, the resource'URI is something like this: http://localhost/myWar/testServlet/testResource 1- Let's say that the RestletServlet is configured like this : url-pattern/*/url-pattern and the application as follow: router.attach(/testResource,HelloWorldResource.class); then, the resource'URI is something like this: http://localhost/myWar/testResource best regards, Thierry Boileau On Thu, Feb 28, 2008 at 11:21 PM, Stephan Koops [EMAIL PROTECTED] wrote: Helo TA, try to request /testServlet/testServlet/*, because you give the testServlet double: one times in the web.xml and one times while attaching to the router.

Interesting question came up in one of our implementations today. We check isConfidential() in a Filter and redirect people to https in certain circumstances where the response should not be transmitted in the clear. Some requests are transported over the riap: pseudoprotocol. It seems to me isConfidential() should return true for riap: requests, since the internal requests are not transmitted in the clear.

RE: [GroovyRestlet] GroovyRestlet is hosted as a Groovy Module
Hi Keke,
Thanks again for your contribution!
This is a nice illustration of the interest of Groovy for DSLs and an
opportunity for Groovy users to leverage the Restlet project for their
RESTful Web applications (http://www.restlet.org).
Best regards,
Jerome

RE: First steps with Restlets in Equinox OSGi
Hi Frank, I'm not sure either how to achieve this, normally you would specify a context-param on your ServerServlet. Can't you specify that in OSGi Servlet service? Otherwise, you might want to check this upcoming presentation on Restlet at EclipseCon: RESTful OSGI Web Applications Tutorial http://www.eclipsecon.org/2008/index.php?page=sub/id=462 If Khawaja Shams or Jeff Norris are following this list, they might be able to help you.

There's a bug with follow ups on this site
I try and do a follow up and keep getting blocked because the site thinks I 'm doing top posting. The way I got around it was to take the follow up and remove all characters from the message chain and that seemed to work.
RE: Re: re servlet mapping question
Ted, You do not want to duplicate the servlet mappings with Router URL attachments, as that will only work with double URLs. So in your example your URL would have to be: http://localhost/testServlet/dog/testServlet/dog This is assuming that you are installing your webapp under /ROOT (for Tomcat) or /root (for jetty) There is a level of routing that happens in the servlet container outside of the Restlet engine, and it is determined by either the name of the WAR file or directory in the /webapps directory (again, assuming Tomcat/Jetty). For instance, if your directory structure looks like this: /ServletContainer /webapps /testServlet ... Files for webapp Then your url, with this given web.xml, should REALLY be: http://localhost/testServlet/testServlet/dog/testServlet/dog Because the first /testServlet tells the servlet container to route it to the /testServlet webapp in the /webapps directory. The next /testServlet/dog is your mapping within the web.xml file. The last /testServlet/dog is the Router attachment. A more appropriate mapping would be this: !-- Catch all requests -- servlet-mapping servlet-nameRestletServlet/servlet-name url-pattern/*/url-pattern /servlet-mapping Then you would be able to get to your page using: http://localhost/testServlet/testServlet/dog But, if you just want dog, then you should attach the Router like this: router.attach(/dog,HelloWorldResource.class); Then you could go to: http://localhost/testServlet/dog Again, this is because the servlet container will do an initial routing of the context name based on the webapps you have installed. The Restlet engine works within this context, so Router does not use the initial context (which is testServlet) to map its URLs. As for worries about other servlets, because the Servlet container is routing initially based on context, all other webapps will take precedence. But, this is only a consideration if you install your servlet into the ROOT context. However, the servlet container will still look for installed contexts first before routing the request to the ROOT context. Hope that helps. Also, you may want to check to see if you are getting into the Restlet engine itself. Are you getting a 404 error from your servlet engine, or from the Restlet engine. They will produce different looking pages (unless you are using IE7, in which case the page will be hidden and you will see a generic 404 error displayed by IE itself).

Problems extracting a POST request's entity
Hi all, I'm developing a web-based middleware (the software of my PhD) and I'm trying to use RESTLET. I create a server (and a client) and some restlets to implement the execution dynamics of my software. I'm using XML for the representation of the resources (using JAXB). Well, I tried to implement a GET method and it works, it returns a response with a XML entity on it. But now I'm programming a POST method and I have a problem. I create a request with a XML string as an entity and it seems to be ok (I'm using a StringRepresentation) for this purpose. The code that I use is one of the following: Representation rep = new StringRepresentation(xmlString, MediaType.TEXT_XML); I debug the request and it seems to be well formed. But, when I try to get back the XML string on the handlePost method, I allways obtain a null value. How could I extract the XML String from a request's entity??? (i try to do it using an InputStreamReader but the result is the same) I would appreciate some help regarding this, it takes me two days!! :-) P.D.- Please forgive my poor english :-) -- Sergio Saugar García Área de Ciencias de la Computación e Inteligencia Artificial Departamento de Ciencias de la Computación Edificio Departamental II - Despacho 053 Escuela Técnica Superior de Ingeniería Informática Universidad Rey Juan Carlos Móstoles (MADRID) Clave PGP: http://pgp.rediris.es:11371/pks/lookup?op=getsearch=0xADFA3433 signature.asc Description: OpenPGP digital signature
RE: Problems extracting a POST request's entity
If you read the stream from the representation, or call getText(), then the stream will be consumed and there will be no more data to read. This is also true if you debug a POST on the server side, and call getText(). Your debugger will consume the stream and no more data will be available to the handlePost() method. Only grab the data from the Representation once. If you need to debug, then read it into a temporary variable prior to parsing it, then you can inspect the temp variable without losing the data.
