Windows 7 64ビット（プログラムファイル（x86）もあります）、jre 7およびjdk1.7.0_25を使用しています

IE8 (8.0.7600.16385) でアプレット ファイルにアクセスしているときに、次のエラーが発生しました。

java.security.accesscontrolexception アクセスが拒否されました (java.util.propertypepermission user.dir 読み取り)

ただし、次のページ/結果にアクセスできますが、この例外を通過/処理できません

java.policy ファイルを次のように変更すると、同じファイルが Windows 7 32 ビットで機能します。

// Standard extensions get all permissions by default

grant codeBase "file:${java.home}/lib/ext/*" {
     permission java.util.PropertyPermission "user.dir", "read";
     permission java.security.AllPermission;

私自身は、次のようにjava.policyファイルを置き換えることで解決しましたが、いくつかのマシンで動作しました。
