Jakarta Commons-Net: FTP-Client kann nur eine Datei empfangen
So. Nachdem ich da nun schon seit Wochen dran sitze, frage ich mal hier rum.
Ich verwende für meinen Editor die Jakarta Commons-Net API, um eine Verbindung zu einem FTP-Server herzustellen. Das funktioniert genau solange, bis ich eine Datei heruntergeladen habe. Anschliessend läuft nichts mehr. Code:
Received: 220 dd6918.kasserver.com FTP server ready Send: USER sedit Received: 331 Password required for sedit. Send: PASS ******** Received: 230 User sedit logged in.

Send: QUIT Received: 227 Entering Passive Mode (83,133,49,138,199,114). Der Code, der die Verbindung zum Server herstellt, sieht so aus: Code:
client.connect(host); client.login(user, password); client.enterLocalPassiveMode(); client.setReaderThread(false); Code:
public InputStream getInputStream() throws IOException {
InputStream in = null;
for(int i = 0; i < 5; i++) {
in = fileSystem.getClient().retrieveFileStream(getFullPath());
if(in != null) {
return in;
}
try {
Thread.currentThread().sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
throw new IOException("Could not establish connection");
}
public String getContent(String encoding) {
try {
Reader in = new InputStreamReader(getInputStream(), encoding);
String result = IOUtils.toString(in);
in.close();
return result;
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
Über Hilfe würde ich mich freuen.

Problem ist (endlich) gelöst.
 Es fehlte der Aufruf von client.completePendingCommand(); nach dem Ende der Arbeit mit den Streams.
