如何解决java.security.AccessControlException? [英] How to solve java.security.AccessControlException?

问题描述

我正在尝试通过我的 web 项目上的小程序访问客户端的临时目录.
当我自己运行小程序时，它会毫无问题地获取 tempdir.

I am trying to access client's temp directory through my applet on my web project.
When I run the applet by itself, it gets the tempdir with no problem.

当我尝试使用 javascript 并调用小程序方法在我的项目中获取它时，我的 javascript 控制台上出现 accessControlException.当我尝试读取临时目录下的文件时，我也遇到了同样的异常.

When I try to get it on my project using javascript and calling the applet method, I am having accessControlException on my javascript console. Also I am getting the same exception when I try to read a file under the temp directory.

这正是我所看到的:

java.security.accesscontrolexception access denied (java.util.propertypermission java.io.tmpdir read)
java.security.accesscontrolexception access denied (java.io.filepermission read)
