Java 使用新的权限属性退出“bcprov-ext-jdk16-140.jar”

我有一个applet，它依赖于许多jar。在我将java更新到7.45之后，小程序生成一条消息，说“这个应用程序将在将来的java安全更新中被阻止，因为JAR文件清单不包含Permissions属性” 我在所有清单文件中添加了权限属性“Permissions:all Permissions”，之后我通过6NRJ证书放弃了所有这些JAR

所有jar都经过良好签名，但不幸的是，小程序仅在bcprov-ext-jdk16-140.jar中生成异常

以下是例外情况的详细信息：

我认为bcprov-ext-jdk16-140.jar以前是由bouncy castle签署的

在添加permission属性后，是否有方法重新签名bcprov-ext-jdk16-140.jar

提前感谢您的帮助

我想bcprov-ext-jdk16-140.jar之前是由bouncy castle签署的

不，您可以通过打开jar来验证这一点。你在里面找不到签名

在添加permission属性后，是否有方法重新签名bcprov-ext-jdk16-140.jar

对。打开bcprov jar。使用文本编辑器添加权限属性。使用jarsigner进行签名
