It would appear that starting a listener twice produces this problem. If you
run the following, then the problem occurs:
* BasicConfigurator.configure();
DefaultFtpServer server = (DefaultFtpServer) new
FtpServerFactory().createServer();
server.getListeners().clear();
ListenerFactory listenFactory = new ListenerFactory();
listenFactory.setPort(21);
listenFactory.setServerAddress("127.0.0.1");
DataConnectionConfigurationFactory dataConnFactory = new
DataConnectionConfigurationFactory();
dataConnFactory.setIdleTime(0);
listenFactory.setDataConnectionConfiguration(dataConnFactory.createDataConnectionConfiguration());
Listener result = listenFactory.createListener();
server.getListeners().clear();
server.getListeners().put("127.0.0.1", result);
server.start();
for (Listener listener : server.getListeners().values())
{
listener.start(server.getServerContext());
}
for (Listener listener : server.getListeners().values())
{
listener.suspend();
}*
BUT..... If you remove the following:
* for (Listener listener : server.getListeners().values())
{
listener.start(server.getServerContext());
}
*The listener suspends and an FTP connection cannot be made.
