使用Trusted Library:true使jar文件加载到一个单独的类加载器中，该类加载器是加载applet/WebStart应用程序的类加载器的父类 见： 另见： 这意味着您的受信任代码只能通过Thread.currentThread（）.getContextClassLoader（）访问不受信任的代码
您还可以将Trusted Library:true添加到您所依赖的所有Jar中。“我在Netbeans中看到的清单是，”您在Jar中看到的清单是什么？需要其他JAR吗？为这两个条件添加了清单我添加了堆栈跟踪：除此之外，当我打开控制台时，我可以看到一些奇怪的东西，如：basic:LD-所有JAR文件签名：file:/C:/Users/myC/Documents/NetBeansProjects/jtwain/JTwain3/dist/jnlpcomponent1.jnlp basic：通过安全检查；secureArgs:true，allSigned:false安全性：Istrusted:file:/C:/Users/myC/Documents/NetBeansProjects/jtwain/JTwain3/dist/launch.jnlp false所有内容都已签名。
