Struts tag library 1.2 showing Jasper exception

I want to build a form using the Struts tag library.

web.xml file 

<?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5">
        <session-config>
           <session-timeout>
           30
           </session-timeout>
        </session-config>
        <welcome-file-list>
             <welcome-file>index.jsp</welcome-file>
        </welcome-file-list>
    </web-app>

index.jsp file 

<%@taglib prefix="html" uri="http://struts.apache.org/tags-html"%>
<!DOCTYPE html>
<html:html>
    <html:head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <html:title>JSP Page using Struts html tags</html:title>
    </html:head>   
    <html:body>
        <h1>Hello </h1>
    </html:body>
</html:html>

Output page shows 

HTTP Status 500 -    
type Exception report    

message

description The server encountered an internal error () that prevented it from fulfilling this request.

There's no <html:head> tag.

More or less like the error states.

Next you'll find there's no <html:body> tag either.
