Problem when uploading JAVA FTP file

Good morning,

I'm trying to upload a file to a server via FTP:

 try{
        FTPClient ftp = new FTPClient();
        ftp.connect(server);
        if(!ftp.login(username, password)){
            ftp.logout();
        }
        ftp.enterLocalPassiveMode();
        int reply = ftp.getReplyCode();
        if (!FTPReply.isPositiveCompletion(reply)){
            ftp.disconnect();
        }

        InputStream in = new FileInputStream(ruta);
        ftp.setFileType(ftp.BINARY_FILE_TYPE, ftp.BINARY_FILE_TYPE);
        ftp.setFileTransferMode(ftp.BINARY_FILE_TYPE);
        ftp.storeFile("cartel"+t+".txt", in);
        in.close();
        ftp.logout();
        ftp.disconnect();
    }
    catch (Exception ex){
        ex.printStackTrace();
    }

Everything works correctly (it establishes connection, it does the login correctly and the file is uploaded) but the program remains stopped at the moment that storeFile does. He stays as if he never finished the instruction and does not follow the program. I've seen in several forums and several pages that everyone does the same.

Any ideas of what may be happening?

Thanks in advance.

Good morning

You could try using the following alternate method ( storeFileStream ):

FTPClient ftp = new FTPClient();
boolean transferido = false;
String nombreArchivo = "cartel" + t +".txt"; // de donde viene 't'?
String ftpServer = "servidorFtp";

try {
    // establecemos un tiempo limite de espera para acciones
    ftp.setConnectTimeout(30000);
    ftp.setControlKeepAliveTimeout(60);
    ftp.setControlKeepAliveReplyTimeout(3000);
    ftp.connect(ftpServer);

    if (!FTPReply.isPositiveCompletion(ftp.getReplyCode()))
        throw new Exception(String.format("Conexion no realizada > Codigo: %s", ftp.getReplyCode()));

    ftp.setFileType(FTP.BINARY_FILE_TYPE);
    ftp.enterLocalPassiveMode();

    boolean bLoginOk = ftp.login(user, password);

    InputStream inputStream = new ByteArrayInputStream(content.getBytes());
    OutputStream outputStream = ftp.storeFileStream(remoteFile);

    byte[] bytesIn = new byte[4096];
    int read = 0;

    while ((read = inputStream.read(bytesIn)) != -1)
        outputStream.write(bytesIn, 0, read);

    inputStream.close();
    outputStream.close();

    transferido = ftp.completePendingCommand();

    // si no se envio
    if (!transferido)
        throw new Exception(String.format("Archivo %s no tranferido!", nombreArchivo));

} catch (Exception e) {
    throw new Exception("Error enviando archivo a [" + ftpServer + "] Detalles: " + e.getMessage());

} finally {
    try {
        if (ftp.isConnected()) {
            ftp.logout();
            ftp.disconnect();
        }
    } catch (IOException ioe) {
        throw ioe;
    }
}
