JAVA安全AccessControlException:在浏览器上运行小程序时拒绝访问

Question

尝试在浏览器中运行小程序时出现以下错误。该小程序中包含文件访问代码：

java.security.AccessControlException: access denied (java.lang.RuntimePermission getenv.RGENGINEJAVA) at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) at java.lang.System.getenv(Unknown Source) at com.socp.components.SOCPMapViewer.bootstrapArcobjectsJar(SOCPMapViewer.java:668) at com.socp.components.SOCPMapViewer.init(SOCPMapViewer.java:130) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Exception: java.security.AccessControlException: access denied (java.lang.RuntimePermission getenv.RGSENGINEJAVA)

当从Elipse IDE调用小程序时，它可以正常工作，但当我在浏览器中使用HTML文件运行它时，它会给出上面显示的错误。请帮我解决这个问题。告诉我如何在HTML上下文中授予以下权限文件：

grant {
  permission java.security.AllPermission;
};
