java - 下载 jre v8 后 Apache Tomcat 不工作

Question

我最近遇到了 Apache Tomcat 7 的问题。我安装了 Java JRE v7。然后，在我更新到 JRE v8 之后，我的服务器出现故障。我注意到在安装 v8 时删除了 jre7，所以我重新安装了 v7，Tomcat 仍然无法正常工作。

下面是我收到的控制台输出。任何帮助将非常感激。谢谢!

我相信 tomcat 7 不能在 JRE 版本 8 中运行。如果你想使用 Java 版本 8，你可以使用不同版本的 tomcat。对于版本 7，你可以从 eclipse 中删除服务器，然后再次添加 tomcat 7 作为你的服务器.
