我正在將基於小程序的應用程序遷移到Web Start應用程序中。JavaFX Web Start應用程序中的自定義SecureClassLoader和權限
在應用程序中，爲了從不同媒體獲取資源和類，需要自定義ClassLoader。它還使用頂部的JavaFX圖層。
將所有權限授予WebStart應用程序，清單已完成並且使用有效證書對jar進行簽名。事實上，如果我不從媒體中獲取這些類，並使用默認的ClassLoader加載它們，那麼一切正常。但是，如果使用了定製的ClassLoader，我們面臨的問題一樣：java.security.AccessControlException：致
訪問被拒絕 （ 「java.net.SocketPermission」 「www.mydomain.com:443」「連接，resolve「）
對於測試提議，自定義SecureClassLoader授予所有權限。這沒有幫助。
我也想更換安全管理器，但我不能：
java.lang.SecurityException異常：JVM共享，不允許設置安全 經理
即使我參數添加到該applet描述符的JNLP內：
PARAM NAME = 「separate_jvm」 值= 「真」
我無法替換經理。
任何人都可以指出我能做些什麼才能授予這些類的權限？無法在客戶端更改策略文件。
這裏我堆棧跟蹤添加到地步電話都來自：
