Hi Thierry,
Thanks for your reply.
I am facing a difference issue now :(
When I use my android client to get the details from google app engine
server it shows "internal connector error"
I am using android emulator for testing when I click the get button in the
application in android emulator it shows "internal connector error"
Also it shows
No available client connector supports the required protocols: 'HTTP' .
Please add the JAR of a matching connector to your classpath.
but I have added the following jars to both my android client and google app
engine server:
org.restlet.jar
org.restlet.ext.net.jar
com.noelios.restlet.ext.httpclient_3.1.jar
com.noelios.restlet.ext.net.jar
com.noelios.restlet.ext.servlet_2.5.jar
com.noelios.restlet.jar
Here is the log cat file for android:

I have added internet permission in the manifest file.
Here is the code for server:

import org.restlet.Restlet;
import org.restlet.data.Protocol;
import org.restlet.resource.Directory;
import org.restlet.routing.Router;
public class TestServerApplication extends Application {
/**

*/
public static void main(String[] args) throws Exception {
Component component = new Component();
component.getServers().add(Protocol.HTTP, 8080);
component.getClients().add(Protocol.CLAP);
component.getClients().add(Protocol.FILE);
component.getDefaultHost().attach(new TestServerApplication());
component.start();
}
@Override
public Restlet createInboundRoot() {
Router router = new Router(getContext());
// Serve the files generated by the GWT compilation step.
Directory dir = new Directory(getContext(),"war:///");
router.attachDefault(dir);
router.attach("/contacts/123", ContactServerResource.class);
return router;
}
}
Please help me out.
Thanks in advance
