Accessing File on UNIX

[Tanuja rj]

I have one application which uploads file On UNIX server.Same application later wanted to access file from unix server
by giving credentials(Application connect to server by giving domain name,username,password).
Unix server do not have any FTP/HTTP listener its just one terminal on network.

Can anyone please suggest a way to access file on unix server either by using Java API or some other means?

Thanks.

How does the file get uploaded if there's no services running?

[Tanuja rj]

It is in-house framework which does file uploading task.
Even if we set aside uploading part question is how can one authenticate access for file stored on Unix using java/other API.

How does the framework do the uploading? You need to know how that server can be accessed before you can think about how to access the uploaded files.
