Answer 1

BufferedInputStream in = null;
BufferedOutputStream out = null;
OutputStream os;
os = new BufferedOutputStream(response.getOutputStream());
in = new BufferedInputStream(new FileInputStream(file));
out = new BufferedOutputStream(os);
byte[] buffer = new byte[1024 * 8];
int j = -1;
while ((j = in.read(buffer)) != -1) {
    out.write(buffer, 0, j);
}
