  错误:The content of element type “web-app” must match “(icon ,display-

name ,description ,distributable ,context-param*,filter*,filter-mapping*,listener*,servlet*,servlet-

mapping*,session-config ,mime-mapping*,welcome-file-list ,error-page*,taglib*,resource-env-

ref*,resource-ref*,security-constraint*,login-config ,security-role*,env-entry*,ejb-ref*,ejb-local-ref*)”.

- No grammar constraints (DTD or XML schema) detected for the document.

  web.xml头部配置:

  < xml version=”1.0” encoding=”UTF-8” >
<!DOCTYPE web-app PUBLIC “-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN” “”>
<web-app>

  原因:文档内容标签顺序不符合web-app_2_3.dtd规范

  解决方案

  1:严格按照提示上的顺序排列

  2:删除<!DOCTYPE 。。。。这段内容

ps:最好按照标准顺序排列,删除不是常规方法(适合强迫症看到红叉受不了的银)
