RE: Tomcat with Restlet behind Proxy: Communication Error (1001)
Hi, I have done so, and in the startup-arguments I have set to following: -DproxySet=true -DproxyHost=proxy.intern -DproxyPort=8080 -DproxyUsername=myUsername -DproxyPassword=mySecret -Dhttp.nonProxyHosts=localhost|127.0.0.1|192.168.100.210 Now the Redirector does try to access the resource via proxy, but I get 407 - Proxy Authentication Required. The -DproxyUser and -DproxyPassword seem not to work... do you know perhaps why? Thank you, ab jlouvel wrote: It is however possible to replace it with a client connector based on HttpURLConnection.

RE: How to write an Universal redirector
Hi, It is really nice of you to help me. It is quite possible, that my problem is in the project set-up. The RestLet libraries are from 25.2.2010. I have minimized the Eclipse project to a single onModuleLoad function and the minimum of server-side classes (2). What it large makes are the libraries I use… You can see the project setup in the image file I have also attached. http://www.kybernetika.de/tmp/restlet/TestRestlet.zip http://www.kybernetika.de/tmp/restlet/TestRestlet.zip http://www.kybernetika.de/tmp/restlet/TestRestlet.gif http://www.kybernetika.de/tmp/restlet/TestRestlet.gif The best of all would be, if I could use on the client side something like this: ClientResource client = new ClientResource(“http://weather.yahooapis.com/forecastrss?w=615702”); without having to implement ANY server side stuff… A BIG BIG thank you one more time! Have a nice weekend. ab jlouvel wrote: Hi ab, It would help if you could package a small project reproducing your issue.

Re: How to write an Universal redirector
Hi, I have made some tests with Fiddler2. I have executed the same Request/Headers that I have posted above, and got a normal/JSON answer from my Tomcat running on 8080.

Re: How to write an Universal redirector
Hallo Thierry,
After I have changed the mode to Redirector.MODE_SERVER_DISPATCHER my
createInboundRoot method looks like this:
@Override
public synchronized Restlet createInboundRoot() {
Router router = new Router(getContext());
router.setDefaultMatchingMode(Template.MODE_STARTS_WITH);
router.attach(/RESTfulServices, new Redirector(getContext(),
http://localhost:8080/RESTfulServices{rr};,
Redirector.MODE_SERVER_DISPATCHER));
return router;
}
but I still receive no answer. My std output looks like this:

GWT, ClientResource, Same Origin Policy (SOP)
Good evening everyone,
What do I need to make from GWT a simple (GET and PUT) request to a
non-localhost service without having to implement any server side code? The
following example does not work. (Probably becouse of the Same Origin
Policy):
ClientResource r = new
ClientResource(http://xxx.xxx.xxx.xxx:/services/my_service;);
r.setOnReceived(new Uniform() {
public void handle(Request request, Response response) {
System.out.println(response.getStatus());
}
});
r.get();
Cheers,
ab

How to write an Universal redirector
Hello everybody,
Could please anyone help me to write a universal redirector to match all
requests and to redirected them to a remote host?
Example:
Start: /redirect/RESTfulServices/resources/customers/pkey/2176172632
Finish:
http://192.168.100.1:8080/RESTfulServices/resources/customers/pkey/2176172632
GWT Client side:
ClientResource r = new
ClientResource(/redirect/RESTfulServices/resources/customers/pkey/2176172632);
Server side class TestRestletApplication extends Application (my web.xml was
changed to forward all /redirect/* requests to TestRestletApplication)
Router router = new Router(getContext());
router.attach(/RESTfulServices, new MyRedirector(getContext(), null)); //
-- this is wrong
and MyRedirector class:
public class MyRedirector extends Redirector {
public MyRedirector(Context context, String targetTemplate) {
// By default, the mode is MODE_CLIENT_DISPATCHER
super(context, targetTemplate);
}
@Override
protected Reference getTargetRef(Request request, Response response) {
Reference ref = request.getResourceRef();
ref.setHostDomain(192.168.100.1);
ref.setHostPort(8080);
// -- here is missing something
return ref;
}
}
Thank you for helping me.
