Report developed in 6i and open and run in 10g, Web Layout is not working

Initially reports were developed in Reports 6i now we need to convert into 10g. I just opened the .rdf in Reports10g. Report is successfully running in paper layout and showing the data. But when i try to run the report in Web Layout im getting a BLANK INTERNET EXPLORER SCREEN. Why is it so? What should i do to run my report successfully in Web Layout? When i see Web Source, i am seeing the below code,
<%@ taglib uri="/WEB-INF/lib/reports_tld.jar" prefix="rw" %>
<%@ page language="java" import="*" errorPage="/rwerror.jsp" session="false" %>
<%@ page contentType="text/html;charset=ISO-8859-1" %>
<rw:report id="report">
<rw:objects id="objects">
<meta name="GENERATOR" content="Oracle 9i Reports Developer"/>
<title> Your Title </title>
<rw:style id="yourStyle">
<!-- Report Wizard inserts style link clause here -->
<rw:dataArea id="yourDataArea">
<!-- Report Wizard inserts the default jsp here -->
Please, guide to achive the Web Layout Report.
Thanks & Rgds,

The answer is in the Migration FAQ :
When I open an Oracle6i Reports Developer report in the Oracle Reports Builder 10g and run my Web layout, I get an empty Web page in my browser.
