I have to write a servlet that copies a text file from a remote server to the local server. The remote server can be anything - Unix, NT.
How that can be done without using URLs or NFS? I think my problem is the naming convention.

i don't think your problem is the naming convention, but the protocol for transfer of remote data ...
the remote machine manages its own File System and if you want to get some files from there, you will need some kind of server program (working there) that can handle your file request and return the appropriate file(s)

there are many standard protocols for data exchange (FTP, HTTP, even POP3 ...) and the URL object in Java is just a wrapper of the appropriate protocol so if you create HTTP URL object and call getInputStream, the URL object will send the appropriate HTTP request message and will handle the HTTP response message, giving you the pure data. so does FTP URL object ...
(there is no magic at all)

if you are working on LAN with NFS you can probably use File object with appropriate name ...

hope this helps

(if you really don't want to use URL objects, you have to write your own server app. clients should connect to the server (using Sockets) ask for particular file; the server will send them the file and they can save it ...)
