Archiving File on Shared Folder in Linux using java code

Question

Hi All,
I have a requirement wherein I have to ftp a file (Feed.txt) from windows FTP server to Linux machine1 and archive the same file (with timestamp suffixed on file name like Feed.txt_22April) on Linux Machine2. I am
trying to achieve this through java code. I am able to ftp the file(Feed.txt) from windows ftp server to Linux machine1 /opt/ftproot directory and archiving the same file under /opt/ftproot/archive directory of Linux
Machine1 with timestamp suffixed on file name.
My archiving requirement is still not achieved. So, for that I created a shared folder “/temp/shared” on Linux Machine2 and mounted the /temp/shared folder of Linux Machine2 on /opt/ftproot/archive folder of
Linux Machine1 using following command:
# mount LinuxMachine2: /temp/shared /opt/ftproot/archive
Note: I have given full permission on both the folders.
Logically, archiving the Feed.txt with timestamp in it name under /opt/ftproot/archive folder should create the file in /temp/shared folder of Linux Machine2. But instead of archiving the file on
/opt/ftproot/archive folder, it archive the file on /opt/ftproot folder.
In my java code, I have specified copyDir as “/opt/ftproot” and archiveDir as /opt/ftproot/archive”.
The code is being run from Linux Machine1 as a schedule task.
Please help.
PFB the code snippet:

- You are connecting to a ftp server. I am guessing you didn't write that.
- Get a flexible ftp client, there are many but make sure it shows you the ftp result codes.
- Figure out how and if the ftp server will do what you want.
If it does do what you want then ftp client will let you do the same thing.
If that ftp server doesn't allow you to do it then you must do one of the following
- Find a different server
- Change the requirements
- Find a way to impose the requirements using a tool in addition to ftp like some command executed through telnet.
