签名的jar引发java.lang.reflect.InvocationTargetException

Question

我写了一个JApplet，它生活在一个签名的jar中（我购买了证书）。 我正在努力使它在Web服务器上工作。 当我使用标准的“ applet”标签调用它时，我会看到一个nag对话框，该对话框识别出jar已签名。 然后，它显示另一个对话框，要求阻止小程序内容。 它提到我混合了我的签名jar和其他未签名的jar（即javax.mail.jar，mysql-connector-java-5.1.25-bin.jar和其他一些）。 它导致以下控制台转储：

即使我在html代码中指定了控制台输出，控制台输出也警告“ 缺少权限清单属性 ”和“ 缺少代码库清单属性 ”。

我也尝试过通过jnlp文件运行它。 当我尝试这样做时，似乎无法识别罐子是否已签名，如以下所示：

它导致相同的控制台转储。

我正在开拓新的领域。 有人可以阐明这一点吗？ 我知道这可能是基本的东西，但是，我可以在此基础上另辟eyes径。

在此先感谢您的帮助，建议等。

我可以一次签名一个罐子来解决这个问题。 我运行了该应用程序，并观看了控制台消息。 每次，控制台输出都会抱怨另一个jar的安全性已过期。 我一个个地签了罐子，问题解决了。 我不确定这是否是处理此问题的适当方法，但是，它解决了问题。
