签名的jar抛出java.lang.reflect.InvocationTargetException

Question

我写了一个JApplet，它位于一个签名的jar中（我购买了证书）。我正在努力让它在Web服务器上运行。当我使用标准的“applet”标签调用它时，我得到了一个nag对话框，它识别出jar被签名。然后它会显示另一个要求阻止applet内容的对话框。它提到我混合了我签名的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：

控制台输出还会警告“缺少权限清单属性”和“缺少代码库清单属性”，即使我在html代码中指定了它们。

我也试过通过jnlp文件运行它。当我尝试这一点时，它似乎没有认识到罐子已签名，如下所示：

导致相同的控制台转储。

我正在开拓新局面。有人可以对此有所了解吗？我知道它可能是基本的东西，但是，我可以用另一套眼睛。

提前感谢任何帮助，建议等。

我能够通过一次签名一个罐子来解决这个问题。我运行了应用程序并观看了控制台消息。每次，控制台输出都会抱怨具有过期安全性的不同jar。我一个接一个地签了问题的罐子，问题解决了。我不确定这是处理这个的合适方法，但是，它解决了这个问题。
