How to get the functionality of downloading files from internet on my jsp

Question

i have a jsp page that lists me the names of the zip files in a paricular directory on a remote computer over the network.wat i want to do is download those files.so when i click on them it gives me "page cannot be displayed" error.but when i go to that remote machine and run the same jsp to list me the files and download the same it allows me to download the files.but i want the same functionality over the network.so i think that that link is looking for that file locally instead of looking for them over the network.so is it so that i need to give the ip of the remote machine from where i want to download the file and if yes then how and if no then is there any way that i can do it some other way.
in short this functionality is like downloading some file from the net like downloading software or music....i want to incorporate the same on my jsp.please guide me.

Answer 1

You can try this, Give the URL from where you want to Download.......
import java.io.*;
import java.net.*;
public class DnldURL {
public static void main (String[] args) {
URL u;
InputStream is = null;
DataInputStream dis;
String s;
try {
u = new URL("http://username:[email protected]:8080/files/for/me/file.txt");
is = u.openStream(); // throws an IOException
dis = new DataInputStream(new BufferedInputStream(is));
while ((s = dis.readLine()) != null) {
System.out.println(s);
} catch (MalformedURLException mue) {
System.out.println("Ouch - a MalformedURLException happened.");
mue.printStackTrace();
System.exit(1);
} catch (IOException ioe) {
System.out.println("Oops- an IOException happened.");
ioe.printStackTrace();
System.exit(1);
} finally {
try {
is.close();
} catch (IOException ioe) {
Here in the URL we will give username and password, if the remote system is password protected.
