I am trying to write an FTP Client and Server that will allow me to send a file from the client to the server via anonymous FTP. However, I keep getting 550 Permission Denied. I am able to do other things like download a file from the server, or get a list of the files in the directory, but whenever I try to do a download it says 550 Permission Denied. The result is the same whether I log in or use anonymous FTP.
I don't see any problems with my code, but I have tried running it on different networks and computers with the same result. Is there a problem with the code that I don't see, or do I have to do something with the router/firewall?
I am writing both the client and server in Java and running Windows. The libraries I am using are Apache Commons FTP Client and Apache FTP Server.
Here is the client. The commented out code is for uploading and getting a list of the files in the directory.
import org.apache.commons.net.ftp.*;
import java.io.*;
import java.net.*;
public class Client
{
public Client()
{
// Do nothing
}
public void transferFile(String ipAddress)
{
// For uploading
FileInputStream file = null;
// For downloading
// FileOutputStream file = null;
try
{
InetAddress address = InetAddress.getByName(ipAddress);
FTPClient ftpClient = new FTPClient();
ftpClient.connect(address, 5000);
ftpClient.login("anonymous", "");
ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
ftpClient.enterLocalPassiveMode();
// For uploading
file = new FileInputStream(new File("C:/SoundFiles/Send/Test1.txt"));
// For downloading
// file = new FileOutputStream(new File("C:/SoundFiles/Receive/Test2.txt"));
// For uploading
boolean success = ftpClient.storeFile("/Receive/Test2.txt", file);
// For downloading
// boolean success = ftpClient.retrieveFile("/Send/Test1.txt", file);
// For listing the files on the server's directory
/*
FTPFile[] directoryFiles = ftpClient.listFiles();
System.out.println("There are " + directoryFiles.length + " files");
for(int i = 0; i < directoryFiles.length; i++)
{
System.out.println(i + ": " + directoryFiles[i].getName());
}
*/
if(success)
System.out.println("Success.");
else
System.out.println("Fail.");
ftpClient.logout();
ftpClient.disconnect();
}
catch(IOException e)
{
e.printStackTrace();
}
finally
{
try
{
if(file != null)
file.close();
}
catch(IOException e)
{
e.printStackTrace();
}
}
}
public static void main(String[] args)
{
Client client = new Client();
client.transferFile("Enter your IP address here");
}
}
Here is the server.
import org.apache.ftpserver.FtpServer;
import org.apache.ftpserver.FtpServerFactory;
import org.apache.ftpserver.ConnectionConfigFactory;
import org.apache.ftpserver.usermanager.impl.BaseUser;
import org.apache.ftpserver.listener.ListenerFactory;
import org.apache.ftpserver.ftplet.FtpException;
import org.apache.ftpserver.ftplet.UserManager;
public class Server
{
public Server()
{
// Do nothing
}
public void startServer()
{
FtpServer server = null;
try
{
FtpServerFactory ftpServerFactory = new FtpServerFactory();
ListenerFactory listenerFactory = new ListenerFactory();
listenerFactory.setPort(5000);
ftpServerFactory.addListener("default", listenerFactory.createListener());
ConnectionConfigFactory configFactory = new ConnectionConfigFactory();
configFactory.setAnonymousLoginEnabled(true);
ftpServerFactory.setConnectionConfig(configFactory.createConnectionConfig());
BaseUser user = new BaseUser();
user.setName("anonymous");
user.setPassword("");
user.setHomeDirectory("C:/SoundFiles");
UserManager userManager = ftpServerFactory.getUserManager();
userManager.save(user);
server = ftpServerFactory.createServer();
server.start();
}
catch (FtpException e)
{
e.printStackTrace();
}
// Stop the server after 10 seconds
try
{
Thread.sleep(10000);
}
catch(InterruptedException e)
{
e.printStackTrace();
}
if(server != null)
server.stop();
}
public static void main(String[] args)
{
Server server = new Server();
server.startServer();
}
}
This is the output I keep getting from the server.

Any suggestions on how I can get this to work are much appreciated.
