Invalid element name:- display-name One of the following is expected:- distributable, context-param , filter, servlet, etc

I am trying to solve this error... This error is showing by default when I create new project within dynamic web project option.. The scenario is project creates successfully but when I expand web.xml file inside webapp folder errors are showing....

Pls click the code of web.xml file:-

<?xml version="1.0" 
encodingg="UTF-8"?>
<web-appxmlns:xsi="http://
www.w3.org/2001/XMLSchema-
instance"
