How to send files using Restlet

[billy]

Hi, 

I'm trying to upload files using Restlet as client and server. For the server, 
I am using RestletFileUpload and it works. 

However, for the client, I have no clue how to put files. All I have achieved 
so far is:

            Request request = new Request
(Method.GET, "http://localhost:8182/";);
            Client client = new Client(Protocol.HTTP);
            client.handle(request);
                Response resp = client.handle(request);

The client can reach the server, but of course with an error: 

the request doesn't contain a multipart/form-data or multipart/mixed stream, 
content type header is null

How can I set it so that the client can point to to some file and post it to 
the server? Also, is compression supported and how to do it? I have found some 
decode method. But is it for text encoding, e.g., to UTF-8, and not for 
compression?

Thanks, billy
