a question about resolving urls for resources.
Hello, I'm designing an application that retrieves some email messages from a
DB back end.
I'd like to use Rest to put and get messages on the db. A component is later
responsible of retrieving them from the DB and storing them on a PEC inboox
and for getting mails from the inboox and storing them on the DB. The DB
layer is essential for data maintenance since the inboox is constantly
cleared.
In my application each mail is identified by a msg_id and each mail can have
several attachments
So I have the following urls :
mail_list : get all the application related emails and post a new message
mail_list/{msg_ID} in order to get, update and delete a specific message
mail_list/{msg_ID}/attachment to get all the attachments and post a new one
mail_list/{msg_ID}/attachment/{att_id} to get, put and delete a specific
attachment
and so on.
My doubt is related to how to configure the urls in order to manage requests
for email specific attachments : mail_list/{msg_ID}/attachment/{att_id}
There are two parameters here {msg_ID} and {att_id} . I can attach the
resource mail list to the url /mail_list and the engine will be able to
manage the parameter msg_ID through the API.
However, how can I configure the mappings in order to reach the attachment
resource if the url always starts with mail_list/{msg_ID}/attachment..?
I' d be greatful isf someone may help me resolving this doubt.
Thanks.
Antonio.

accessing restlet web (deployed on tomcat for instance) resources from a not java client, is it possible?
Hello I would like to know if it's possible to connect to a Restlet web resource 8deployed on Tomcat or an other web server) through a client that is written in an other language. To better explain, let's suppose that we have defined some restlet resources which return some type of representation, let's say DomRepresentattion or ObjectRepresentation. Is it possible to write a .net or C# client that connects to the restlet web server and can understand the result returned from the server? Since they connect through http and speak html, it should be feasible even if the client can not understand reslet based output representations like DOMRepresentation or what ever else. Am I wrong? Is there any example that may let me better understand this kind of integration? Thanks in advance.

how to provide several guards for a resource when using jax-rs extensions
Hi all, I'm trying to port the restlet-gwt sample to a jax-rs style using the appropriate classes and annotations. However, I do not know how to set two guards on a same resource. In the original sample, two guards performing basic and digest authentication were added on two different urls /guarded and guarded_digest. This was possible since the router.attach method was being invoked. Now I'm wondering whether the same thing is possible to achieve using a JsrApplication instance. If I use the setGuard method I'm unable to distinguish which Guard should be invoked depending on a particular url. So how can I do? May someone help me? The documentation at the link: http://wiki.restlet.org/docs_1.1/13-restlet/28-restlet/57-restlet.html is a little vague and according to previous posts, it also seems to be partially wrong since the createRoot method is being missed and all the activity has been moved to the construcor. Moreover, the ExampleApplication should extend ApplicationConfig and not Application, if I do not get wrong. Thanks to alla for your support. It's a really great project and I'd like to contribute for it. -- View this message in context: http://n2.nabble.com/how-to-provide-several-guards-for-a-resource-when-using-jax-rs-extensions-tp1619094p1619094.html Sent from the Restlet Discuss mailing list archive at Nabble.com. -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=980176
restlet can work together with servlets?
Hello, I'd like to know if restlets and servlets may work together. I saw that there's a servlet adapter for using restlets in a tomcat environment and that the servlet mapping must match /*. >From shat I remember about servlets mapping, this should not prevent other servlets from working in the container. To better explain, if I introduce an other servlet, let's say TestServlet in the deployment descriptor and map it to the following url, /ping/* a request http://somehost:8080/web_root/ping should be served by a TestServlet instance and so the restlet engine should not be invoked. Am I wrong? If this is true, which restlet-servlet integration scenario might be feasible? May a sevlet perform some controller logic and then delegate to the restlet engine or may they work together in order to serve different requests and logic? The restlet engine could provide resource's representations and the servlet might provide some other logic that does not fit well with the restlet implementation. I don't know if I'm saying strange things and would like to have a piece of advice from someone expert in the matter. Thanks in advance. Bye.

Re: problem with restlet-gwt
Hi Rob, thanks for your support. Unfortunatelly the web.xml has not been overwritten. I controlled it more times and it's ok. What can be wrong? Did you try the sample on windows? It seems like the gwt engine is finding something in the module. When we perform a gwt-rpc call, we have to add a servlet entry in the module and the gwt module in this way knows how to route the request. When we run the gwtshell under eclipse, I saw that it starts a tomcat instance. It also deploys the restlet resources there in order they to be found by the gwt engine? My question is does the gwt shell behave as a web container and deploy the resources (in the server folder) within it as we had created a web project and put the restlet based application classes within it? If I start the restlet TestServer component as a standaolne application and then run the shell again it complains of an already used address and so the server side should work well even if I can not see the TestServer's sytem.out statements in the console. I read several books on gwt (gwt in practice and Pro web 2.0 with gwt ... and so on) and I have seen different solutions but noone clearly refers to this particular integration with rest. Can You please help me?

problem with restlet-gwt
Hello, I imported the sample restlet-gwt project within eclipse 3.4 but I'm unable to connect to the restlet resource. When I click on the close button It complains of the following error "unable to find 'ping.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?" I get this error both creating a new project with all the dependencies and importing the already configured one and running the .launch file. I am using eclipse in windows and I changed the gwt_home setting and the gwt.linux settings to point to the right files and path. I don't understand why it's looking within the module to find the resocuces. It should use the restlet-gwt jar file and open a http connection. Can you please suggest me a solution? Moreover has someone succeded in configuring the module to run on a real tomcat instance? Which kind of servlet is it necessary to configure in the deoployment descriptor? GwtServletWrapper should not work in web mode so ServerServlet should be enough? And how to pass the module information? The documentation is not very detailed as far as these concerns and a complete example should help very much. Thanks.
