RE: Re: Unable to access servletContext?
Hi,
I'm using the code recently send by Thierry on the list to get the servlet
context
And it's working great.
ServletContextAdapter adapter = (ServletContextAdapter) getContext();
ServletContext servletContext = adapter.getServletContext();
System.out.println(servletContext.getRealPath(""));
My web.xml is a little different, i put the params into the "servlet" tag,
using the "init-param" instead of "context-param". But as far as i remember, it
doesn't matters.
ServerServletRouter
com.noelios.restlet.ext.servlet.ServerServlet
org.restlet.application
com.bla.bla.rest.RestletRouter
ServerServletRouter
/rest/*

Hi Thierry,
Yes, my application does implement the contructor that you are describing. I
can successfully cast to an ApplicationContext but not to the
ServletContextAdapter.
My web.xml is very simple as it only contains the restlet adapter, servlet
mapping and context params needed for the ServerServlet.
org.restlet.application
com.nn.ws.restlet.MyApplication
RestletServlet
com.noelios.restlet.ext.servlet.ServerServlet
0
RestletServlet
/resources/*
Anything else to try?

Ok, I'm going to investigate the 2nd way, seems to fit my need. Thanks for the quick reply. -- Julien Balas JDAS Rennes -Message d'origine- De : Jerome Louvel [mailto:[EMAIL PROTECTED] Envoyé : jeudi 5 juillet 2007 16:59 À : discuss@restlet.tigris.org Objet : Re: Multiples rest service using multiples servlet in tomcat. Julien, The ServerServlet was designed to adapt on Servlet Webapp to exactly one Restlet Application. The ServerServlet caches the instantiated application inside the Webapp context which explains the behavior you observe. This needs to be better documented in the Javadocs. Now, there are different ways to achieve what you need: 1) Create two WARs, on for each Restlet Application, with only one ServerServlet in each 2) Merge your two Restlet Applications into one, and add a Router at the root of this app to handle the routing internally. 3) Rely on the ServletConverter to have a lower level integration between your Servlets and Restlets (but you loose portability to Restlet standalone mode).

RE: Re: Multiples rest service using multiples servlet in tomcat.
I'm using 1.0.2
The very strange thing is that I have a previous version of my app and the 2
servlets are working perfectly.
(I can prove it with a war) :)
But I can't find the differences.
The web.xml is the same
The .class files are the same.
I tried the war on another tomcat (on a Linux box) as well, just to be sure
it's not a problem on my machine.
I get the same "404 error".
Btw, who is sending this error?
The restlet framework ?
Is there a way to get more information during the execution of the framework ?

Hi Julien,
Which version of Restlet are you using?
There was a related bug fixed in 1.0.2:
- Fixed bug in ServletConverter causing the caching of the base URI and
inability to handle requests with various base URI style (IP address and domain
names for example). Report by Ryan Daum.
Best regards,
Jerome

Multiples rest service using multiples servlet in tomcat.
Hi
I'm trying to have 2 servlets using 2 restlet in order to provide 2 REST
services in the same tomcat.
But I have a strange behavior.
The first Servlet called works perfectly, but not the second one.
For the second one, I get a "404 error", but not a "tomcat 404".
If a call a non existing servlet I got a "tomcat 404", but my error is
not this one, the message is
"The server has not found anything matching the request URI
You can get technical details here.
Please continue your visit at our home page. "
I tried to isolate as much as possible the issue, with a minimal example
of 2 "Hello world" restlet.
The full war (600Ko) is available at
http://julien.balas.free.fr/EventViewer.war
If anybody has a idea..
I guess it's a config issue because each servlet/restlet is working
great if alone in a tomcat.
The 2 classes are very minimal
-
[package and imports]
public class Hello1 extends Application {
public Hello1() {
super();
}
public Hello1(Context parentContext) {
super(parentContext);
}
public Restlet createRoot() {
Restlet restlet = new Restlet(getContext()) {
@Override
public void handle(Request request, Response response) {
response.setEntity(new
StringRepresentation(this.getClass().getName(), MediaType.TEXT_HTML));
}
};
return restlet;
}
}
The tomcat Logs are below
- server startup
- a successful call to "rest2" service
- a 404 on "rest1" service
- another successful call to "rest2" service
INFO: Server startup in 4587 ms

Hello Julien,
if you want to access files that are located inside your "WebContent"
directory, you can use the integrated war client just as follow:
Representation rep =
getContext().getDispatcher().get("war:///files/file.xml").getEntity();
and then use the representation as you want.
NB: you can reuse parameters used for routing. For example, if your restlet has
been reached according to the template
"/segment/{myParameter}":
Representation rep =
getContext().getDispatcher().get("war:///files/file{myParameter}.xml").getEntity();
> What is the relationship between a restlet and a servlet ? none ?
>
The relation between a servlet and a restlet is made with the ServerServlet
extension [1], and more precisely with the ServerServlet class which transmits
servlet calls to your restlets, and the ServletContextAdapter that instantiates
the war client and transmits all servlet context parameters to the restlet
context parameters.
> Is there a way to get to javax.servlet.ServletContext from an

Here is the way to get the servletContext:
ServletContextAdapter adapter = (ServletContextAdapter) getContext();
ServletContext servletContext = adapter.getServletContext();
Please feel free to ask for more details.

access local file in tomcat container
Hi,
[note : I'm new to rest and restlet so my terminology may be not very good]
I've created a rest service using restlet, it's working great when I use the
integrated webserver.
When I try to use my restlet in tomcat, it fail because it can't read a file on
the disk.
My class is called, with the right parameters extracted from the URL, so the
mechanism seems to work.
In my restlet I'm doing things like
new File("/resources/schemas/blabla.xsd")
But in tomcat, I get this error
\resources\schemas\blabla.xsd (Le chemin d'accès spécifié est introuvable)
[file not found in French]
How can I find the physical name of a file in a restlet served by tomcat ?
What is the relationship between a restlet and a servlet ? none ?
Is there a way to get to
javax.servlet.ServletContext
from an
org.restlet.Application ?
Best Regards,
