File Managment Functions

[cowboyrocks2009]

Hi,
I need to develop the functions below for a server in Java. Is there any package or class that I can use ?
I just had a look at one namely...
com.mindbright. net.ftp.
Can you guide me about developing these functions below:-

1) Retrieve file from server
2) Add, edit, delete a file from server.
3) upload / download file from server
4) Logon and version control

Regards
Cowboy

For editing files you can use File and FileWriter API.
For uploading to the server, use Apache's commons-fileupload API.
