The content of element type "..." must match in web.xml

Question

I have a problem with my web.xml file. The error:

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*)".

However, my web.xml file is in the order what error say.

Here is my web.xml:

<!DOCTYPE web-app PUBLIC          "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"          "http://java.sun.com/dtd/web-app_2_3.dtd" >  <web-app>     <display-name>Archetype Created Web Application</display-name>      <context-param>         <param-name>javax.faces.STATE_SAVING_METHOD</param-name>         <param-value>client</param-value>         <description>State saving method: 'client' or 'server' (=default). See JSF Specification 2.5.2</description>     </context-param>            <context-param>         <param-name>javax.servlet.jsp.jstl.fmt.localizationContext</param-name>         <param-value>resources.application</param-value>         <description></description>     </context-param>      <servlet>         <servlet-name>Faces Servlet</servlet-name>         <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>         <load-on-startup>1</load-on-startup>     </servlet>            <servlet-mapping>         <servlet-name>Faces Servlet</servlet-name>         <url-pattern>/faces/*</url-pattern>     </servlet-mapping>      <welcome-file-list>         <welcome-file>index.html</welcome-file>         <welcome-file>index.htm</welcome-file>         <welcome-file>index.jsp</welcome-file>         <welcome-file>default.html</welcome-file>         <welcome-file>default.htm</welcome-file>         <welcome-file>default.jsp</welcome-file>     </welcome-file-list>  </web-app> 

I use WebLogic 10.3.4. Any idea about the problem?

Answer 1

One very simple solution which solves my problem.

Change the schema reference from

<!DOCTYPE web-app PUBLIC    "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"    "http://java.sun.com/dtd/web-app_2_3.dtd" >  <web-app></web-app> 

to this

<?xml version="1.0" encoding="UTF-8"?>  <web-app xmlns="http://java.sun.com/xml/ns/javaee"           version="2.5"           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"           xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">           // ...          // your all content goes here  </web-app>
