Re: How to send files using Restlet

[billy]

Hi Thierrry, Jerome:

I received Thierrry's sample code to put files:

Component component = new Component();
component.getServers().add(Protocol.HTTP, 8182);

component.getDefaultHost().attach("/essai",
        new MyApplication(component.getContext()));
component.start();

/* Launches a simple client */
FileRepresentation rep = new FileRepresentation(
        "d:\\temp\\test.txt", MediaType.TEXT_ALL, 0);
EncodeRepresentation encodedRep = new EncodeRepresentation(Encoding.GZIP,
        rep);
Client client = new Client(Protocol.HTTP);
Response response = client.put("http://localhost:8182/essai/";, encodedRep);
System.out.println("******" + response.getStatus());

/* Stops the server */
component.stop();

Thanks a lot. The follow-up questions are:
1) For the server, is there a way to store the file AND the parameters that 
the client may send along?
2) Does "Encoding.GZIP" mean to zip/compress the file before sending? If yes, 
why there is no corresponding method for the server to unzip the file? Is 
the "Encoding" automatically recognized by the server?



Also, I original had this server code (found in this forum or other related 
forum) to store files and the parameters that clients may send:


DiskFileItemFactory factory = new DiskFileItemFactory();
RestletFileUpload upload = new  RestletFileUpload(factory);
try
{
    List items = upload.parseRequest(request);
    String xml_text="";

    //récupérer le xml et l'image
    int i = 0;
    for (final Iterator it = items.iterator(); it.hasNext(); ) {    
        FileItem fi = (FileItem)it.next();
        
        File saveTo = new File("c:\\temp\\FileReqReceived" + i + ".txt");
        fi.write(saveTo);
        
        i++;
    }
}


However, I did not know how to send files using Restlet so I used other 
methods to write the client. I tried to use the above server code to receive 
file requests sent by using this code:

FileRepresentation rep = new FileRepresentation(
        "d:\\temp\\test.txt", MediaType.TEXT_ALL, 0);
EncodeRepresentation encodedRep = new EncodeRepresentation(Encoding.GZIP,
        rep);
Client client = new Client(Protocol.HTTP);
Response response = client.put("http://localhost:8182/essai/";, encodedRep);
System.out.println("******" + response.getStatus())


There was an error:

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

It seems that the server is expecting multipart/form-data. How can I modify 
the server code so that it can receive both multipart/form-data and other 
types of data?

I understand lengthy documentation for Restlet may not be available at the 
moment. What other documents would you recommend so that I can learn from them 
and then apply the reasoning, coding style etc. when I write develop Restlet 
applications?
