Can anyone explain me what's wrong with the following code? I tried different hosts, FTPClientConfigs, it's properly accessible via firefox/filezilla... The problem is I always get empty filelist without any exceptions (files.length == 0). I use commons-net-2.1.jar installed with Maven.
FTPClientConfig config = new FTPClientConfig(FTPClientConfig.SYST_L8);
FTPClient client = new FTPClient();
client.configure(config);
client.connect("c64.rulez.org");
client.login("anonymous", "anonymous");
client.enterRemotePassiveMode();
FTPFile[] files = client.listFiles();
Assert.assertTrue(files.length > 0);
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:
