JavaアプレットがHTMLで動作しない

Question

アプレットを作成しました。このアプレットは、アプレットビューアで完全に機能します。しかし、私はこのアプレットのクラスファイルを自分自身に署名したJarファイルとともにディレクトリに入れ、アプレットタグ付き.HTMLファイルを作成すると動作しません。私はjava.security.AccessControlException: access deniedを得続けます。 どうすればこの作品を作れますか？それは問題であり、その下にアプレットが埋め込まれている方法です下に、ここでソースコードは、ある：

証明書がブラウザで信頼されていないか、ユーザーが明示的な許可を与えていない。あなたは私たちにコード（確かに良いこと）を与えましたが、署名そのもの、ブラウザ、またはアプレットを埋め込んだ方法については何も与えませんでした。
