I create a servlet in Tomcat that pass a file to the client, like this:

      // Open the file and output streams
       FileInputStream in = new FileInputStream(file);
       OutputStream out = response.getOutputStream();

       // Copy the contents of the file to the output stream
       byte[] buf = new byte[1024];
       int count = 0;
       while ((count = in.read(buf)) >= 0) {
           out.write(buf, 0, count);
       }
       in.close();
       out.close();
        }

When the client download the file and save it, the name of the file is
the name of the servlet.
The big question is: how can I show a name that I want instead of the
name of the servlet?

Thank you
