cvc-complex-type.2.3: Element 'web-app'

本文记录了一次解决工程中Servlet无法运行并出现404错误的经历,发现问题是由于web.xml文件中的注释标记写错导致。通过删除错误的注释标记,成功解决了Servlet无法启动的问题。
不知改动了什么,工程里的servlet一直无法运行,出现404错误。
但新建一个工程,servlet正常运行,纳闷不得解

同时web.xml提示错误cvc-complex-type.2.3: Element 'web-app' cannot have character [children], because the type's content type is
element-only

网上没有统一的答案。看了半天,原来web.xml注释标记写错了,删除注释一切正常
在此记录,引以为戒!
