我有一个 java 小程序，我将它添加到一个 html 文件中。我的 java 小程序包括 jess 库，我批处理了一个文件，其中包含我在 jess 中的规则。当我从 Netbeans IDE 运行我的项目时，一切都很完美并且可以正常工作。但是当我将我的文件夹复制到 wampserver 的 www 目录中以运行我的 html 时，Java 控制台给了我以下错误：

 Jess reported an error in routine import
    while executing (import java.lang.Boolean).
  Message: Error during execution.

AccessControlException建议此代码需要在受信任的环境中运行。为此，需要对其进行数字签名。

请注意，在客户端计算机上写入文件通常不是由小程序完成的。也许你正在错误地使用 API，虽然我不知道，所以不能肯定地说。
