我将基于applet的应用程序迁移到Web Start应用程序中。
在应用程序中，需要自定义ClassLoader才能从不同媒体中获取资源和类。它还在顶部使用了JavaFX层。
所有权限都授予WebStart应用程序，清单已完成，jar使用有效证书进行签名。事实上，如果我不从媒体中获取类，并使用默认的ClassLoader加载它们，那么一切正常。但是，如果我使用自定义ClassLoader，我们会面临以下问题：
引起：java.security.AccessControlException：访问被拒绝 （＆＃34; java.net.SocketPermission＆＃34;＆＃34; www.mydomain.com:443"＆＃34; connect，resolve＆＃34;）
对于测试提案，自定义SecureClassLoader授予所有权限。这没有用。
我也试图更换安全管理器，但我不能：
java.lang.SecurityException：JVM Shared，不允许设置安全性 管理器
即使我将参数添加到jnlp中的applet描述符：
PARAM name =＆＃34; separate_jvm＆＃34;值=＆＃34;真＆＃34;
我无法取代经理。
任何人都可以指出我可以做些什么来授予这些类的权限？无法在客户端更改策略文件。
在这里，我将堆栈跟踪添加到调用来自的位置：
java.security.AccessControlException: access denied ("java.net.SocketPermission" "www.mydomian.com" "resolve")
