Я сделал апплет. Этот апплет прекрасно работает в appletviewer. Но когда я помещаю файл класса этого апплета в каталог вместе с файлом Jar, в который я сам подписал, и создаю файл .HTML с тегами апплета, он не работает. Я продолжаю получать java.security.AccessControlException: access denied.
Как я могу сделать эту работу? Вот исходный код, ниже это проблема, а ниже это то, как встроен апплет.

Встраивается так:
<html>
<body>
<applet code=RSLoad.class archive="RSLoad.jar" width=100% height=100%>
</applet>
</body>
