I need help please, thanks in advance...

Well I am using netbeans for programming a data reporting site, I need a chart to represent these data. [I have JFreeChat and JCommon in my netbeans Library].

Well in my I have my main page called "index.jsp" with a button liking to an action[.JAVA] which contains this sample java code then I'll forward it to another page to view the graph... But I don't know yet and haven't found yet how how to apply the JFreeChart Graph to a page using the JAVA [.java] code.

HELP! JFreeChart Displayed on WEB using netbeans-javacode.jpg
The code I used for my button at index.jsp is:<%@page language="java" contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

<%@page import="java.text.*"%>
<%@page import="java.util.*"%>
<head>
<title>Report</title></head>
<body>
<form method="post" action="/Report/AppServlet?action=StackedBarChart&forward=/index_1.jsp">
<input type="submit" value="Test Button">
</form>
</body> </html>

Could someone please help me. I need it as soon as possible, I am too pressured, sorry.
