How to send a file to browser for downloading?

When client request for a file, I use this code to send it:

public static Result download(String file) {
    File file = getRealFile(file);
    return Ok(file);
}

But I found the browser will not download it, but display its content instead. The response header:

Content-Type    text/plain
Transfer-Encoding   chunked

What's the correct way to send a file?

Update

Per Razvi's answer, I found an answer seems good for this question: https://stackoverflow.com/a/1074925/342235

But do we really have to set so many headers?

header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=$filepath");
header("Content-Type: mime/type");
header("Content-Transfer-Encoding: binary");
// UPDATE: Add the below line to show file size during download.
header('Content-Length: ' . filesize($filepath));

You need to set the Content-Disposition header. I believe the value of the header should be attachment. See Manipulating the response doc for this.

For play 2.0 the following works without explicitly setting the header:

ok(new FileInputStream(file))
