Getting client address from server

It depends what kind of server this is and what sort API you have for communication with it.

Generally speaking what you want is the remote address of the Socket. However you may not have direct access to the socket.

So please what kind of server is this (something you wrote yourself, Tomcat, something else)?

From this I conclude that you do have access to the socket instance in question. So use the getInetAddress method of socket.

See this [url=http://java.sun.com/j2se/1.5.0/docs/api/java/net/Socket.html#getInetAddress()]http://java.sun.com/j2se/1.5.0/docs/api/java/net/Socket.html#getInetAddress()[/url]

Then that machine is not a server in the context of your Java app.

There has to be some sort of server or server-ish process running on all those nodes, or a client on those nodes that knows to go out to the "main" box and fetch the files. Some options:

* Create your own Java program that acts as a server on those boxes to take file push requests from the main box.

* Create your own Java program that acts as a client on those boxes to go out and pull files from the main box.

* Start up ftp servers on those boxes (should come with the OS or be downloadable) and use an ftp client (library can be obtaine from apache.org I think) in your Java program on the main box to push the files.

* Have those nodes share a disk or portion of a disk, mount those nodes' shared drives on the main box, and use regular file I/O to copy the files.

Bottom line: You cannot do this purley from the "server" side. There has to be some setup on the "clients" to enable them to accept the file.
