java linux server remote connection and read the file size

java remote connection linux, and read the given path, given the size of the file extension
looks like an application to read files on the host can get to the File object , and then get the size ;
but the landing to a non- host , you get less than a File object , and only use java call linux command "ls-l *. xx" approach , the results of its command and then io operations read the file size .

I ask is that right ?
There is no efficient solution? Log in remote linux I use ganymed-ssh2-build210.jar

org.apache.commons.net.ftp.FTPClient really good
But this is the bank's monitoring function , their servers will not just install ftp ftp or log in
so it can only operate with the io

conn = new Connection (ip, port);

boolean isAuthenticated = conn.authenticateWithPassword (user, password);
if (isAuthenticated == false) {
