Du nutzt keine Suchmaschine -- trotzdem kommst du mit Java voran?

Wollen mal nicht so sein, die Details (von der angegebenen Adresse)::

import java.io.File;import java.io.FileInputStream;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;
 import org.apache.commons.net.ftp.FTP;import org.apache.commons.net.ftp.FTPClient;
 /** * A program that demonstrates how to upload files from local computer * to a remote FTP server using Apache Commons Net API. * @author www.codejava.net */public class FTPUploadFileDemo {
    public static void main(String[] args) {        String server = "www.myserver.com";        int port = 21;        String user = "user";        String pass = "pass";
         FTPClient ftpClient = new FTPClient();        try {
             ftpClient.connect(server, port);            ftpClient.login(user, pass);            ftpClient.enterLocalPassiveMode();
             ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
            // APPROACH #1: uploads first file using an InputStream            File firstLocalFile = new File("D:/Test/Projects.zip");
             String firstRemoteFile = "Projects.zip";            InputStream inputStream = new FileInputStream(firstLocalFile);
             System.out.println("Start uploading first file");            boolean done = ftpClient.storeFile(firstRemoteFile, inputStream);            inputStream.close();            if (done) {                System.out.println("The first file is uploaded successfully.");            }
             // APPROACH #2: uploads second file using an OutputStream            File secondLocalFile = new File("E:/Test/Report.doc");            String secondRemoteFile = "test/Report.doc";            inputStream = new FileInputStream(secondLocalFile);
             System.out.println("Start uploading second file");            OutputStream outputStream = ftpClient.storeFileStream(secondRemoteFile);            byte[] bytesIn = new byte[4096];            int read = 0;
             while ((read = inputStream.read(bytesIn)) != -1) {                outputStream.write(bytesIn, 0, read);            }            inputStream.close();            outputStream.close();
             boolean completed = ftpClient.completePendingCommand();            if (completed) {                System.out.println("The second file is uploaded successfully.");            }
         } catch (IOException ex) {            System.out.println("Error: " + ex.getMessage());            ex.printStackTrace();        } finally {            try {                if (ftpClient.isConnected()) {                    ftpClient.logout();                   ftpClient.disconnect();                }            } catch (IOException ex) {                ex.printStackTrace();            }        }    }
 }
