I'm trying to write a program that writes a text file to an ftp server. I'm using this library "com.jscape.inet.ftp". But I'm getting an exception "com.jscape.inet.ftp.FtpException". I set up the server so that it is possible to write to it, so i do not know what the problem is.  
  Thanx in advance for looking it up.

You can simply do this, then you need no other libraries:

      public void writeToFileViaFtp() {
            try {
                  URL ftp = new URL("ftp://username:password@somewhere.com/somefile.txt");
                  URLConnection conn = ftp.openConnection();
                  conn.setDoOutput(true);
                  PrintWriter out = new PrintWriter(conn.getOutputStream());
                  out.println("Line 1");
                  out.println("Line 2");
                  out.close();
            }
            catch (Exception e) {
                  e.printStackTrace();
            }
      }

Hi, this question is for CEHJ. Thanx for answering my question. However I still get an error when running your programm. It says "protocol doesn't support output". Would that be a problem with my server or the code?
I appreciate your help.
Thanx.

That would probably be a username/password thing - code works fine for me

Hey man that is cool. My respects to you. However i still get the error.This is what I'm doing

one class:

import java.net.*;
import java.io.*;
public class Servers
{
         public Servers()
         {
         }
         public void writeToFileViaFtp() {
          try {
               URL ftp = new URL("ftp://try:trytry@69.194.83.97/somefiles.txt");
               URLConnection conn = ftp.openConnection();
               conn.setDoOutput(true);
               PrintWriter out = new PrintWriter(conn.getOutputStream());
               out.println("Line 1");
               out.println("Line 2");
               out.close();
          }
          catch (Exception e) {
               e.printStackTrace();
          }
          }
}


the other class:

public class ServerTwo
{
    public static void main(String[] args)
    {
        Servers server = new Servers();
        server.writeToFileViaFtp();
    }
}


What am i doing wrong.
Thanx

Might be a network issue. Can you connect with any other ftp client from the same place as you're running the java to the same ftp server?

Are you going to need to be doing more than just write a file to the ftp server?
