Facing issues in creating new Dynamic Web Project in Eclipse

I am trying to create a webapp in eclipse, but I am facing issues in web.xml. Web.xml is giving below error.

Description Resource    Path    Location    Type
Cannot resolve the name 'javaee:descriptionGroup' to a(n) 'group' component.    web.xml /ESApi/WebContent/WEB-INF   line 1117   Problem

Below is my web.xml, I have included servlet-api.3.0.jar in build path.

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://ift.tt/ra1lAU" 
xmlns="http://ift.tt/nSRXKP" 
xmlns:web="http://ift.tt/LU8AHS" 
xsi:schemaLocation="http://ift.tt/nSRXKP http://ift.tt/1eWqHMP" 
id="WebApp_ID" 
version="3.0">
  <display-name>ESApi</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>
  <servlet>
    <description></description>
    <display-name>RequestResponder</display-name>
    <servlet-name>RequestResponder</servlet-name>
    <servlet-class>com.abc.esap.server.RequestResponder</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>RequestResponder</servlet-name>
    <url-pattern>/RequestResponder</url-pattern>
  </servlet-mapping>
</web-app>

Please help in resolving this error. Thanks
