Error in jsp file

I am facing some issue with the jsp using struct 2.1.8.1

My Jsp code is

<%@ page language="java"  pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="html" uri="/struts-tags" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Onstar Forumz</title>
</head>
<body bgcolor="#FFFFFF" text="#000000">

<%@ include file="/header.jsp" %>

<html:form action="UserverifyAction" name="userForm" type="com.onstar.user.in.form.UserForm">
<html:text property="username" style="position:absolute;left:720px;top:271px;width:112px;font-family:Arial;font-size:16px;z-index:15" name="username" value="" ></html:text>
<html:password property="password" style="position:absolute;left:720px;top:302px;width:112px;font-family:Arial;font-size:16px;z-index:16" name="password" value="" ></html:password>

<font style="font-size:13px" color="#FFFFFF" face="Arial"><b>User name :</b></font></div>
<div id="wb_Password" style="position:absolute;left:631px;top:307px;width:82px;height:16px;z-index:18;" align="left">
<font style="font-size:13px" color="#FFFFFF" face="Arial"><b>Password   : </b></font></div>
<div id="wb_signin" style="position:absolute;left:843px;top:304px;width:101px;height:23px;z-index:19;" align="left">
<input type="image" src="images/gold_sign.gif" id="signin" alt="" align="top" border="0" style="width:101px;height:23px;"></div>
</html:form>

<%@ include file="/footer.jsp" %>
</body>
</html>

Error Message:

I have placed the struts2-core-2.1.8.1.jar in lib folder as well as well I have configured the buildpath with the jar file(struts2-core-2.1.8.1.jar)

Please help me...Thanks in Advance

*Please* don't use the old Struts 1 tag prefix for the Struts 2 tag libraries--besides that it's just misleading, it's also inaccurate, as the S2 tags include a lot more than just HTML-emitting tags. The canonical taglib prefix for the S2 tags is simply "s".

The error message is telling you *precisely* what's wrong. S2's text tag doesn't render a text input field.

I am baffled by your use of CSS.
