启动tomcat时的jsp索引异常

Question

我有一个奇怪的问题。让我们从错误开始：

这是在我启动tomcat时给出的（在一个类中由于异常而中断调试之后）。我已经尝试注释了所有JSP中的所有代码，并检查了每个文件是否都在部署目录中。一切看起来都很好，奇怪的是应用程序运行良好。我找不到问题，也不知道从哪里开始找！

有人可以帮助我，或者已经有了类似的问题？

非常感谢。

Answer 1

我发现了包含的问题，部署目录中的一个旧webapp给出了该错误。删除该webapp后，错误消失了，但tomcat启动时调试中的执行中断仍然会发生：

Answer 2

File "/WEB-INF/jsp/includes.jsp" not found] with root cause
org.apache.jasper.JasperException: /index.jsp (line: 3, column: 1) 

如果要包括此内容，则包括。jsp内部索引。jsp，然后在从一开始删除后重试。

<%@ include file="WEB-INF/jsp/includes.jsp" %>

如果文件包括。jsp仍然存在于您的项目中，请尝试清理tomcat工作目录。而不是清理并重建项目，然后再试一次。
