We need FTP jar. You can find it in reference.

 

package file.ftp.upload;

import java.io.File;

import java.io.FileInputStream;

import java.io.IOException;

import java.io.OutputStream;

import java.net.URL;

import java.net.URLConnection;

import org.apache.commons.net.ftp.FTPClient;

 

public class UploadFileFTP {

public static void main(String[] args) {

FTPClient ftpClient = new FTPClient();

FileInputStream fis = null;

String hostname = “[Path for FTP Server]”;

int port = 21;

String user = “[user login]”;

String pass = “[password login]”;

String fileName=null;

File folder = new File(“D:/ftp/process/”); //Directory from local

File[] listOfFiles = folder.listFiles();

try {

ftpClient.connect(hostname, port);

boolean login = ftpClient.login(user, pass);

if(login){

System.out.println(“Connection established…”);

for (File fileDownload : listOfFiles) {

if (fileDownload.isFile()) {

fileName = fileDownload.getName();

System.out.println(“Nama file : “+fileName);

File uploadToCurrent = new File(“D:/ftp/process/”+fileName);

String filePath = uploadToCurrent.getAbsolutePath();

System.out.println(“Path file : “+filePath);

fis = new FileInputStream(filePath);

//Path from FTP Server

String uploadPath = “Current/”+fileName;

System.out.println(uploadPath);

System.out.println(“Start uploading first file”);

boolean done = ftpClient.storeFile(uploadPath, fis);

fis.close();

if (done) {

System.out.println(“The first file is uploaded successfully.”);

}

}

}

}

} catch (Exception e) {

e.printStackTrace();

System.out.println(e.getMessage());

}finally{

try {

if (ftpClient.isConnected()) {

boolean logout = ftpClient.logout();

ftpClient.disconnect();

if (logout) {

System.out.println(“Connection close…”);

} else {

System.out.println(“Connection fail…”);
