    Default Uploading File to server ( Apache.commons.net)

    Hello, it's my first post, so if it is wrong place to write I apologize in advance.
    I have problem with uploading file to server which I've been trying to solve for few days, but that was been way to nowhere.
    Code looks like that, and I am succesfully logging into server, but I can't do anything more.
    Java Code:
    FTPClient client = new FTPClient();
    String fileName = "regulamin.txt";
    FileInputStream fis = null;
    int reply;
        try {
            fis = new FileInputStream(fileName);
     
            client.connect("ftp.polishtennis.web44.net");
     
            System.out.println(client.getReplyString());
     
            reply = client.getReplyCode();
     
             if(!FTPReply.isPositiveCompletion(reply)) {
                    client.disconnect();
                    System.err.println("FTP server refused connection.");
                    System.exit(1);
                  }
     
            client.login("user", "pass");
            System.out.print(client.getReplyString());
     
            client.changeWorkingDirectory("/public_html");
            System.out.println(client.getReplyString());
     
            client.storeFile("regulamin.txt", fis);
            System.out.println(client.getReplyString());
     
            client.logout();
            System.out.println(client.getReplyString());
    And I always get errors while uploading, listing files or anything its upsetting-.-"

    It's a Socket exception, clearly means that either you are behind firewall or your sockets can not listen/communicate properly.

    Oh dude, you are fu*&%^g awesome, ahh, I've wasted circa 40 hours over that issue and you've solved it in few seconds. I've just forget to add exception in window's firewall. But it doesn't explain, why program could connect to server but file transfer was impossible... why does windows behave like that?

    If you will read the exception trace, you will find the answer yourself.

    Firewall is the surfaced problem, the underlying problem is you should connect to the FTP server using local passive mode.
