在的AccessControlException的Applet [英] AccessControlException in Applet

问题描述

这个小程序运行在日食观察者的罚款。我无法从任何浏览器上运行。我怎样才能解决这个问题？我从我的Java小程序的控制台得到这个错误：

在异常线程AWT-EventQueue的-2java.security.AccessControlException：访问被拒绝（java.awt.AWTPermission watchMousePointer）

解决方案

小程序在浏览器中运行使用安全管理器。有迹象表明，在浏览器中的applet不允许做很多事情。如果你坚持，你的小程序做这些事情，部署你的applet为签署的applet

This applet runs fine in eclipse viewer. I cannot run it from any browser. How can I resolve this issue? I get this error from my java applet console:

解决方案

Applets running in a browser use a Security Manager. There are many things that applets in a browser are not allowed to do. If you insist that your applets do these things, deploy your applet as a signed applet
