推荐答案

首先阅读本文件 - 并决定c。将小程序允许什么样的$ C $的。由于@AndrewThompson指出的（见的意见）的签署小程序没有安全限制，因为它们是数字签名（签字）这证明，他们来到未被篡改从特定的受信任的作者。

First of all read this document - What Applets Can and Cannot Do? ** and decide what kind of code an applet allows. As @AndrewThompson pointed out (see comment) that signed applets do not have the security restrictions because they are digitally signed (signature) which proves that they came untampered from a particular trusted author.
