Apache Commons Net FTPClient and listFiles()
Only using enterLocalPassiveMode()
did not work for me.
I used following code, which worked.
ftpsClient.execPBSZ(0);
ftpsClient.execPROT("P");
ftpsClient.type(FTP.BINARY_FILE_TYPE);
Complete example is as below,
FTPSClient ftpsClient = new FTPSClient();
ftpsClient.connect("Host", 21);
ftpsClient.login("user", "pass");
ftpsClient.enterLocalPassiveMode();
ftpsClient.execPBSZ(0);
ftpsClient.execPROT("P");
ftpsClient.type(FTP.BINARY_FILE_TYPE);
FTPFile[] files = ftpsClient.listFiles();
for (FTPFile file : files) {
System.out.println(file.getName());
}
Found it!
The thing is you want to enter passive mode after you connect, but before you log in. Your code returns nothing for me, but this works for me:
import org.apache.commons.net.ftp.FTPClient;
import java.io.IOException;
import org.apache.commons.net.ftp.FTPFile;
public class BasicFTP {
public static void main(String[] args) throws IOException {
FTPClient client = new FTPClient();
client.connect("c64.rulez.org");
client.enterLocalPassiveMode();
client.login("anonymous", "");
FTPFile[] files = client.listFiles("/pub");
for (FTPFile file : files) {
System.out.println(file.getName());
}
}
}
Gives me this output:
