我在 CentoOS 上安装了 apache tomcat 7。当我进入 apache 起始页时，出现错误 500:

message Unable to compile class for JSP:

description The server encountered an internal error that prevented it from fulfilling this request.

exception

我尝试重新安装几次，但这无济于事。我红色关于错误 500，但用户添加了您的页面。我在 apache 起始页找不到任何关于错误 500 的信息。

这是我第一次使用apache tomcat。

已解决:我安装了 java-1.7.0-openjdk-devel 并开始工作。谢谢!

我的猜测是较旧的 JDK 是安装的一部分。
centos版本？
