Are you referring to the /tmp directory on the server  from which the applet was generated, or the machiene on which the applet is running?

The Request is from an Applet and you want to access files on Server...
I think You need a Server Application (ie. CGI) to do this.
You applet need to open a Socket to Server that contains your Applet, and applet sends request, then Server Application receive request and access files on Server.
There are many ways to communicate with server:

(1) HTTP: You need a CGI on the Web Server to receive the Request from the Applet
      in Applet:
          URL url1=new URL("xxx.asp?myname="+name);
          DataInputStream dis=new DataInputStream(url1.openStream());
      in CGI (if you have IIS + ASP, it will be very simple):
          1. use 'Request.QueryString("myname") to receive the data
          2. use the Scripting.FileSystem to create file

(2) Create an application on Server. it opens a Server Socket to receive any request from Client and do anything.
      And, Applet opens socket to communicate with Server.

(3) RMI , You can write the Server Application with simple programing in Java.
