Hallo!
Beim Versuch in Java eine FTP Verbindung mit dem Code
1 |
|
2 |
|
3 | import org.apache.commons.net.ftp.FTPClient;
|
4 | import org.apache.commons.net.ftp.FTPFile;
|
5 | import org.apache.commons.io.FileUtils;
|
6 | import java.io.IOException;
|
7 |
|
8 | public class UpdateNeues {
|
9 |
|
10 |
|
11 | public static void main(String[] args) {
|
12 | FTPClient client = new FTPClient();
|
13 | try{
|
14 | client.connect("server");
|
15 | if ( client.login("user", "pass")){
|
16 | System.out.append("Userdaten akzeptiert");
|
17 | client.listFiles();
|
18 | };
|
19 |
|
20 |
|
21 |
|
22 |
|
23 |
|
24 | client.disconnect();
|
25 |
|
26 | } catch (Exception ex){
|
27 | ex.printStackTrace();
|
28 | }
|
29 |
|
30 |
|
31 | }
|
32 | }
|
aufzubauen, erscheint folgende Fehlermeldung
