org.apache.jasper.JasperException：在第[38]行处理[index.jsp]时发生异常

标签： tomcat9

我的apache主页抛出以下异常。我可以通过URL访问经理和其他页面。这甚至都不是我的代码，也找不到针对此的任何特定解决方案。我没有对默认设置进行任何更改，并且在我上次检查时效果很好。 我主要通过eclipse IDE来使用它进行开发，并且从那里可以正常工作（因为我不必从那里访问主页）。

似乎tomcat9与jdk8不相处（我发现）。尝试与jdk12（以及openjdk12）一起工作！没有尝试使用jdk9，jdk10和jdk11。现在我回想起我第一次使用jdk8时第一次安装tomcat9时遇到的相同问题，但它不起作用（仅在主页上）。Apache9的受支持Java版本声明为8 and later，因此我怀疑是我的一个特定问题（如果您也遇到这个问题，请在评论中打我）。
