Будет загружен тест загрузки постлетов, но не апплет

Question

Я использую Java-апплет для загрузки HTTP, который называется «Postlet».Я настроил PHP-скрипт для хранения файла и сохранения имени файла в базе данных.Когда я использую простую тестовую форму HTML для загрузки одного изображения, оно работает нормально, но не работает, когда я использую настоящий апплет, даже если я выбираю только один файл.

Java-апплет работает так, как будто все прошло успешно, сообщая, что загрузка изображения прошла успешно, но файл нигде не найден.Я даже использовал новый апплет с упрощенным файлом PHP, и апплет снова говорит, что все прошло успешно.Но он ничего не вводил в базу данных и не загружал файл.

Мой сценарий здесь минус некоторые вещи и каталоги файлов MySQL в целях безопасности: P

<?php
session_start();


$albumID = $_SESSION['albumID'];
$author = 1;
/*
The following file enables the uploading of each image from the java applet.

PLEASE NOTE, THIS FILES IN ITS PRESENT FORM IS A MASSIVE SECURITY RISK, AND
SHOULD NOT BE USED WITHOUT DOING EITHER OF THE FOLLOWING:

- PROTECTING THE ACCESS OF THE FILE BY THE USE OF SESSION VARIABLES (DO NOT
  PROTECT IT BY USING HTTP PASSWORDS)
- ENSURING THAT UPLOADED FILES ARE NOT ACCESSIBLE TO THE WEB (UPLOAD FILES
  TO A DIRECTORY ABOVE THE DOCUMENT ROOT)
*/

/*

Есть идеи, почему он не работает?
