Store file in Restlet put method

Question

I'm trying to store a file which is sent via PUT to a Restlet resource.

The curl statement looks like this:

curl -X PUT "http://localhost:8080/EAIConfig/ri/media" --data-binary img019.png

And this is my resource implementation:

@Override
protected Representation put(Representation entity) throws ResourceException {
    try {
        InputStream in = entity.getStream();
        OutputStream out = new FileOutputStream("/Temp/media-file.png");
        IOUtils.copy(in,out);
        out.close();
        in.close();         
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return new EmptyRepresentation();
}

This runns without errors. But the resulting /Temp/media-file.png does contain the name of the sent file instead of the sent image data.

Any idea how to get the file contents?

I don't think it's a problem in your Restlet code but rather in the way you call it using curl.

You forget the '@' in the parameter --data-binary . You should use something like that:

curl -X PUT "http://localhost:8080/EAIConfig/ri/media" --data-binary "@img019.png"

I made a try with your code and it works for me. I suppose that you the class IOUtils from Commons IO.

One small comment. Your method put needs to be defined as public and with annotation @Put to be directly called by Restlet ;-)

Hope it helps you, Thierry
