Restlet and consuming/storing files

Question

How would one handle consuming an attachment from a client POST/PUT request on the server side and store that file in a local folder, all using Restlet ?

My thoughts are as follows:

Setup Server as follows:

new MailServerComponenet.start();

public MailServer(){
    getServers().add(Protocol.HTTP, 8111);
    getDefaultHost().attachDefault(new MailServer());
    server.getContext().getParameters().set("tracing", "true");
}

@Put
public void store(Form form){
    // *And here is where I am not sure*
}

Thanks for any insight and help in advance.

Here are the following steps you should follow to implement your Restlet application:

Create a component
```
Component component = new Component();
```

Create an application and attach it on the component

component.getServers().add(Protocol.HTTP, 8182);

Application application = new MyApplication();
component.getDefaultHost().attachDefault(application);

component.start();

Configure the application within the method createInboundRoot (create a router and attach server resource on it)

public class MyApplication extends Application {
    @Override
    public Restlet createInboundRoot() {
        Router router = new Router();
        router.attach("/test", MyServerResource.class);
        return router;
    }
}

Implement the server resources

public class MyServerResource extends ServerResource {
    @Post
    public Representation handlePost(Representation repr) {
        (...)
    }
}

Now the global frame is implemented, I would wonder how you would send the content to Restlet. Is it simple binary content within the request payload or multi-part content?

Binary content

@Post
public Representation handlePost(FileRepresentation fileRepr) {
    fileRepr.write(new FileOutputStream(
               new File("/tmp/myfile.txt"))); 
    return null;
}

Multipart content. You can have a look at this answer in this case: File Upload with Description in Restlet

Hope it helps you, Thierry
