cewolf and jsp

[quickcur]

Hi, I use cewolf to put chart in jsp in tomcat. Here is my code

<jsp:useBean id="zc" class="gov.lbl.biosig.struts.zc.ZCData"/>
<cewolf:chart
id="line"
title="ZC"
type="xy"
xaxislabel="Gradient"
yaxislabel="Count">
<cewolf:data>
<cewolfroducer id="zc">
<cewolfaram name="datasetid" value="90"/>
</cewolfroducer>
</cewolf:data>
</cewolf:chart>
<p>
<cewolf:img chartid="line" renderer="cewolf" width="400" height="300"/>

But I got the following error message: (basically, it complains the
line of <cewolfaram name="datasetid" value="90"/>

See http://www.catb.org/~esr/faqs/smart-questions.html#id266352

Some people recommend waiting a 168 hours (i.e. 1 week) before getting
impatient about nobody answering your question. You've only waited 15 hours.

Have you tried asking on the forum at
http://cewolf.sourceforge.net/new/index.html ?
