Chris,

I found this snippet on the web, which shows how you could ask a remote web
server if a URL was available.  It's from
http://www.rgagnon.com/javadetails/java-0059.html

This would only help if the remote file was accessible as a URL.
import java.net.*;
import java.io.*;
import java.net.*;

public class Check {

public static void main(String s[]) {
    System.out.println(exists("http://www.rgagnon.com/howto.html"));
    System.out.println(exists("http://www.rgagnon.com/pagenotfound.html"));
   }

static boolean exists(String URLName){
  try {
    HttpURLConnection.setFollowRedirects(false);
    // note : you may also need
    //        HttpURLConnection.setInstanceFollowRedirects(false)
    HttpURLConnection con =
       (HttpURLConnection) new URL(URLName).openConnection();
    con.setRequestMethod("HEAD");
    return (con.getResponseCode() == HttpURLConnection.HTTP_OK);
    }
  catch (Exception e) {
       e.printStackTrace();
       return false;
       }
  }
