私はずっと答えを探していましたが、私が見つけた最も近いものはサーバーのせいです。
これは私のコードです。私のアプリケーションでは、Zehonライブラリを使用しています。
import com.zehon.BatchTransferProgressDefault;
import com.zehon.FileTransferStatus;
import com.zehon.exception.FileTransferException;
import com.zehon.ftps.FTPsClient;
public class UploadFolderSample {
/**
* Please refer to http://www.zehon.com/FTPs_samples.htm for its full source code
* @param args
*/
public static void main(String[] args) {
String host = "****";
int port = 990;
String username = "******";
String password = "*******";
String sendingFolder = "*******/";
String destFolder = "ftpes:******/";
try {
com.zehon.ftps.FTPsClient ftps = new FTPsClient(host, port, username, password, false);
ftps.folderExists(destFolder);
int status = ftps.sendFolder(sendingFolder, destFolder, new BatchTransferProgressDefault());
if(FileTransferStatus.SUCCESS == status){
System.out.println(sendingFolder + " got ftps-ed successfully to folder "+destFolder);
}
else if(FileTransferStatus.FAILURE == status){
System.out.println("Fail to ftps to folder "+destFolder);
}
} catch (FileTransferException e) {
e.printStackTrace();
}
}
}
そして、これは私のエラーです:

私は本当にいくつかの助けを使うことができました、私は今一週間以上FTPSのことで立ち往生しています。
edit(ダイアログを追加):これは、間違ったポートを使用した場合に発生しますが、少なくともこのようにダイアログが表示されます。
