好吧，我尝试阅读几乎所有文章，但我没有找到任何提示。
从StartSSL收到我的官方证书后，如果没有UNKNOWN发布者警告，我仍然无法启动我的applet。
我用过
jarsigner Connect4Client.jar MyConnectCert
我检查了
jarsigner -verify -verbose -certs Connect4Client.jar
它看起来很好：

那么为什么出版商仍然显示为未知？我错过了什么？另一个证书或者这与Java 7（已安装）或Safari（10.8）有关吗？或者是因为浏览器无法将StartCom识别为有效的CA？
其他信息： 我检查了java控制台并获得了以下内容：

这是StartCom的目标代码签名证书。我之前明确地导入了StartCom证书，以确保找到了这些证书，但仍然没有。
答案 0 :(得分：1)
得到了答案，StartCom回复说他们的证书不能用于Applet签名，这对我来说是一个很大的失望，因为我发现他们在一些网站上提到他们的定价，特别声明他们并不昂贵并且他们启用了Applet签名。这实际上是正确的，但问题是他们的证书将无法解决您想要实现的目标。叹息。
