Forgot to mention the vewrsion:
I tried it in 2.1.1 and 2.2 SNAPSHOT
I am currently trying to stream files from my restlet application.
The following works:
File theFileToDownload = new File("test.mp3");
FileRepresentation rep = new FileRepresentation(theFileToDownload,
MediaType.APPLICATION_OCTET_STREAM);
Disposition disp = new Disposition(Disposition.TYPE_ATTACHMENT);
disp.setFilename(theFileToDownload.getName());
disp.setSize(theFileToDownload.length());
rep.setDisposition(disp);
return rep;
Now I tried switching to JAX RS using:
File file = new File("test.mp3");
Response.ResponseBuilder response = Response.ok((Object) file);
response.header("Content-Disposition",
"attachment; filename=new-android-book.mp3");
return response.build();
Accessing the ressource causes Restlet to throw the following exception and
stop the download:

This happens with all variations of trying to get files streamed through JAX RS
like:
File file = new File("test.mp3");
ByteArrayOutputStream byteArrayOutputStream = new
ByteArrayOutputStream();
FileInputStream fileInputStream = new FileInputStream(file);
byte[] buffer = new byte[16384];
for (int len = fileInputStream.read(buffer); len > 0; len =
fileInputStream
.read(buffer)) {
byteArrayOutputStream.write(buffer, 0, len);
}
fileInputStream.close();
return Response.ok(byteArrayOutputStream.toByteArray()).build();
Any suggestions on what I might do wrong?
