Hello,
there is a (not so) small constraint with GAE. GAE does not give you access
to the file system, therefore, the File connector has been removed for this
edition.
I suggest that you remove this instruction:
component.getClients().add(Protocol.FILE);
The following one (at the application level) is declarative, but not only.
It says that the current application requires this connector and will not
start if the latter is ont registered:
getConnectorService().getClientProtocols().add(Protocol.FILE);
The lack of this instruction has one consequence. The application will
start, but the first request using this protocol will fail if there is no
FILE connector registered.
Well, back to your problem.
You can either serve static files from the classpath or the "war" context
since gae app runs inside a servlet container.
// Here is the code when serving wia the War context (assuming your files
are under the war root directory)
@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;
}
You can notice that there is a "war" protocol, and an associated "war"
connector (just as for the "FILE", "HTTP", "CLAP", etc protocols).
The declaration of this war connector is implicit, it is only shipped with
the "org.restlet.ext.servlet" extension.
// Here is the code when serving wia the Clap context (assuming your files
are under the war root directory)
@Override
public Restlet createInboundRoot() {
Router router = new Router(getContext());
// Serve the files generated by the GWT compilation step.
Directory dir = new
Directory(getContext(),LocalReference.createClapReference(LocalReference.CLAP_CLASS,
"<path to your files>"));
router.attachDefault(dir);
router.attach("/contacts/123", ContactServerResource.class);return
router;
}
Best regards,
THierry Boileau
