Do you have a question ?

[sinchan banerje]

yes. In my environment this code is working properly while the server is linux and client is windows.

ut it is causing some problem in other environment. Is there a chance that such a thing can happen due to some environment specific problem. If yes, what they may be?

Well champ, this statement of yours is very vague. What happens? Is there an exception? Please TellTheDetails.

Depends what you mean by causing some problem

Please find the below code:

import org.apache.commons.net.ftp.FTPClient;
import java.io.IOException;
import java.io.FileOutputStream;
import java.net.SocketException;
public class ftpTest {
public static void main(String[] args) throws SocketException, IOException {
FTPClient client = new FTPClient();
FileOutputStream fos = null;
fos = new FileOutputStream("D:/myfile.pdf");
String hostfilename = "/home/injm1/XLMP";
client.connect("nmfinccmdev", 22);
client.login("xxx", "xxx");
client.retrieveFile(hostfilename, fos);
fos.close();
client.disconnect();
}
}

But soon after connect i get an following exception

Exception in thread "main" org.apache.commons.net.MalformedServerReplyException: Could not parse response code.

You're using an FTP client to connect to an SSH server. That's not going to work. Either change your port to 21 so you'll actually use the FTP server (if present), or use a different library for SSH handling.

Also, don't post actual login details, as this may encourage some people with bad intentions to login on your system. Replace them with something bogus. I did that for you this time, using "xxx" for both the user name and password.
