You could use something like this:

    URL url = null;
    URLConnection connection = null;
    InputStreamReader stream = null;

    // Parse the URL
    try {
        url = new URL(urlString);
    } catch (MalformedURLException e1) {
        System.out.println("Malformed URL");
        return null;
    }

    // Open a connection to the URL
    try {
        connection = url.openConnection();
    } catch (IOException e) {
        System.out.println("Could not create connection");
        return null;
    }

    // Get the remote file
    try {
        stream = new InputStreamReader(connection.getInputStream());
    } catch (IOException e) {
        System.out.printf("File \"%s\" does not exist!",urlString);
        return null;
    }

What server is it? If its HTTP server, you can request that file and check from response if it exist. If its custom server you have to implement that feature yourself.
