问题 I'm using the Apache-Commons-Net library. I want to know if the FTP server is active-mode or passive-mode. Is there a method like that in the Apache-Commons-Net library?

问题 I m using Apache FTPClient . I was a do a copy of file in a folder just like cp -p , but from Java. How can I do that using 'sendCommand' method or will it be possible any other way?
