我有一个签名的Java小程序(使用自签名证书),具有访问用户的文件系统。 我必须这样做,所以请无回复ALA“你不应该做” :)
问题是,当我从Firefox 3.0执行的Applet / Mac上,一切正常需要,我得到的所有访问,就像它应该。
当我使用萨法尔4 / Mac上,我没有得到访问。 该行我特别有是System.getProperty()的问题(虽然我存根说出来,对FS的访问也不起作用)
String home = System.getProperty("user.home");
我得到的异常如下:
java.security.AccessControlException: access denied (java.util.PropertyPermission user.home read)

正如我所说的,这完美的作品在Firefox。 应该看看今天的Windows浏览器...
有任何想法吗?
