[Prashantust]

Can any one let me know what is th easy way to ftp file from windows to linux machine using java net package.

With the java program mentioned below I am getting below error

Error: org.apache.commons.net.MalformedServerReplyExcepti on: Could not parse response code.
Server Reply: SSH-1.99-OpenSSH_3.9p1

I am able to ftp the same file using winscp. but when I try to ftp from my java program it's throwing above error. I am using commons-net-1.0.0.jar to ftp files.

Here is the java program I am using.

try {
02
            InetAddress ftpHost = InetAddress.getByName("10.10.10.10");
03
            String ftpUserName = "test";
04
            String ftpPassword = "test";
05
            String ftpRemoteDirectory = "/home/tarcher/tmp/ ";
06
            String fileToTransmit = "C:\\sample.txt";

            //A datatype to store responses from the FTP server
11
            int reply;
12
            //Connect to the server
13
            System.out.println("1, "+ftpHost.getHostName()+", "+ftpHost);
14
            ftp.connect(ftpHost.getHostName(), 22);
15
            // After connection attempt, you should check the reply code to verify success.
16
            reply = ftp.getReplyCode();  
17
            System.out.println(reply);
18
            if(!FTPReply.isPositiveCompletion(reply)) {
19
                try {
20
                    ftp.disconnect();
21
                } catch (Exception e) {

                    System.err.println("Unable to disconnect from FTP server " + "after server refused connection. "+e.toString());

Why are you using the 1.0.0 version of commons-net-1.0.0.jar?

There is also a 3.3 version of the same available.....
(http://commons.apache.org/proper/com...wnload_net.cgi)

It might help to repost your code without line numbers,
and telling on which line you got the exception. (check the line number with the line number you get after posting the code)
