我写了一个 JApplet，它存在于一个签名的 jar 中（我购买了一个证书）。我正在努力让它在网络服务器上工作。当我使用标准的“applet”标签调用它时，我会看到识别 jar 已签名的 nag 对话框。然后它会显示另一个对话框，要求阻止小程序内容。它提到我混合了签名的 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）。它会导致以下控制台转储：

控制台输出还警告“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。
我也尝试过通过 jnlp 文件运行它。当我尝试这样做时，它似乎无法识别 jar 已签名，如下所示：
它导致相同的控制台转储。
我正在踏上新的天地。有人可以对此有所了解吗？我知道这可能是一些基本的东西，但是，我可以用另一双眼睛来看待这个问题。
提前感谢您的任何帮助、建议等。
