【问题描述】：
我正在使用 windows 7 64位（也有程序文件（x86））， jre 7 & jdk1.7.0_25
在 IE8 (8.0.7600.16385) 中访问我的小程序文件时出现以下错误
java.security.accesscontrolexception 访问被拒绝（java.util.propertypermission user.dir 读取）
但是我可以进入下一页/结果，但我无法绕过/处理此异常
当我使用以下更改 jav.policy 文件时，相同的文件在 windows 7 32 位中工作。
// 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;
};
// default permissions granted to all domains
grant codeBase "file:C:/Inetpub/wwwroot/applets/*" {
permission java.util.PropertyPermission "user.dir", "read";
permission java.security.AllPermission;
};
grant codeBase "file:C:/Inetpub/wwwroot/applets/ordered.xslt" {
permission java.util.PropertyPermission "user.dir", "read";
permission java.security.AllPermission;
};
grant codeBase "file:C:/Inetpub/wwwroot/applets/nonOrdered.xslt" {
permission java.util.PropertyPermission "user.dir", "read";
permission java.security.AllPermission;
};
grant codeBase "file:C:/Inetpub/wwwroot/applets/common.xsl" {
permission java.util.PropertyPermission "user.dir", "read";
permission java.security.AllPermission;
};
grant {
permission java.util.PropertyPermission "user.dir", "read";
permission java.security.AllPermission;
};

对小程序进行数字签名。它会更快（设置它可能很慢，但在构建过程中只需几分之一秒）。
