Problemas ao utilizar JFreeChart e Cewolf com OC4J

Front-end
#1

Bom dia, estou tendo problemas ao usar JFreeChart e Cewolf no OC4J, alguém já conseguiu montar esses gráficos com essa versão: Oracle9iAS Containers for J2EE 1.0.2.2?

Especificação OC4J:

Java Server Pages (JSP)  1.1 
Servlets  2.2 and 2.3 
Enterprise JavaBeans (EJB)  1.1 and parts of 1.2 
Java Transaction API (JTA)  1.0.1 
Java Messaging Service (JMS)  1.0.1 
Java Naming and Directory Interface (JNDI)  1.2 
Java Mail  1.1.2 
Java Database Connectivity (JDBC)  2.0

Ele não aceita classes compiladas acima do Java 1.3, eu recompilei as classes do meu projeto para essa versão, mas ele esta amarrado a diversos jars, que com certeza não foram compilados com 1.3, qual a alternativa nesse caso?, existe algum jeito antigo para gerar gráficos no JSP ou consigo recompilar esses jars para um 1.3?

Segundo o site do CEWOLF ele suporta JSP 1.1

That should be all you have to do to prepare your application for Cewolf usage. If you encounter any problems in using the Cewolf tags (e.g. “No Tags” is displayed in your containers console) you can additionally put the cewolf.tld (or cewolf-1.1.tld for JSP 1.1 containers) file from the distribution’s etc directory into a directory of your choice under your web application’s root and reference this file as the cewolf tag library from your JSPs.

E segundo o site do JFreeChart ele suporta 1.3.

JFreeChart requires the Java 2 platform (JDK version 1.3 or later). Note that JFreeChart is a class library for use by developers, not an end user application.

No Tomcat funciona sem problemas!

Estou fazendo conforme o texto dele:

<%@ page contentType="text/html; charset=iso-8859-1" errorPage="" %>
<%@ taglib uri="/WEB-INF/cewolf-1.1.tld" prefix="cewolf"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=Cp1252"/>
<title>Exemplo 1</title>
</head>
<body>
<jsp:useBean id="graficoDS" class="br.com.pedrosa.dao.CertificacaoEstadoDataSet"/>
		
<center><h3>GRÁFICOS DE EXEMPLO</h3></center>
		<cewolf:chart id="grafico" title="Certificações por Estado" type="pie3d">
		    <cewolf:gradientpaint>
		        <cewolf:point x="0" y="0" color="#FBFBFB" />
		        <cewolf:point x="350" y="0" color="#F3F3F3" />
		    </cewolf:gradientpaint>
		    <cewolf:data>
		        <cewolf:producer id="graficoDS" />
			</cewolf:data>
		</cewolf:chart>
		<cewolf:img chartid="grafico" renderer="/cewolf" width="710" height="380"/>
</body>
</html>

O estranho que ele da erro interno no servidor e não imprime nada no console, eu tenho essa taglib no meu web.xml, maldito ambiente.
