Returning content stream in HttpServletResponse

[Naresh Bhatia]

I would like to return the content of a document in a HttpServletResponse.
What I have right now is shown below. Is there a better way? Will this scale
for large video content?

InputStream src = new BufferedInputStream(
        document.getContentStream().getStream());

BufferedOutputStream dst = new BufferedOutputStream(
        response.getOutputStream());

byte[] buff = new byte[2048];
int bytesRead;
while((bytesRead = src.read(buff, 0, buff.length)) != -1) {
    dst.write(buff, 0, bytesRead);
}


Thanks.
