I got this issue that is bothering me for a week now,

I'm trying to upload a file xml with ftp using java, nothing too fancy.

After a few web serch i decided to use the ftp4j pack wich, according to the documentation should do the trick.

Point is that this ftp server actually work with Filezilla...

these are a few line of my code:

    public void connect() {
    try {


        String[] con = client.connect(s);
        for (int i = 0; i < con.length; i++) {
            System.out.println(con[i]);
        }

        client.login(user, password);

        s = client.getHost();
        System.out.println(s);

        con = client.help();
        for (int i = 0; i < con.length; i++) {
            System.out.println(con[i]);
        }

        client.changeDirectory(sDir);
        s = client.currentDirectory();

        System.setProperty("ftp4j.passiveDataTransfer.useSuggestedAddress", "1");

        client.setPassive(true);

        System.out.println(client.isPassive());

        client.setType(FTPClient.TYPE_BINARY);

        client.upload(file);


    } catch (Exception ex) {
        Logger.getLogger(ftpConnector.class.getName()).log(Level.SEVERE, null, ex);
        System.out.println(ex.toString());

    }
}

well i get this output:

*

java.net.SocketException: Connection reset

I'm pretty sure the Connection reset is related to the upload command i give with client.upload(file);

all my vars are declared on an upper level.

Thanks for your time, Francesco.

  • Did you try commenting out the System.setProperty("ftp4j.passiveDataTransfer.useSuggestedAddress", "1"); line to see if the client can successfully open a PASV connection to the server using the original control connection address vs. the suggested server address? – ribram Sep 08 '11 at 02:49
  • Tbh i did and it did not work. In order to be sure about this i even set the variable at 0 tho it's still the same. Are you aware of any decent API that i may try out? – Francesco Panina Sep 13 '11 at 20:32
  • Might want to consider using the Apache Commons Net library http://commons.apache.org/net/. That is a solid library that works well. – CodeMonkey Dec 22 '12 at 02:32
