I am trying to download a zip file from a server using the following code but it gives me a tmp.zip of size 1kB. What is the mistake in this program?
try {
URL url = new URL("http://www.nseindia.com/content/historical/DERIVATIVES/2013/JUN/fo18JUN2013bhav.csv.zip");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
InputStream in = connection.getInputStream();
FileOutputStream out = new FileOutputStream("C://Temp/tmp.zip");
copy(in, out, 1024);
out.close();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void copy(InputStream input, OutputStream output, int bufferSize) throws IOException {
byte[] buf = new byte[bufferSize];
int n = input.read(buf);
while (n >= 0) {
output.write(buf, 0, n);
n = input.read(buf);
}output.flush();
}
