Charts with Jasper Plugin does not show in Html format - html

Question

I am using Jasper plugin to create charts in my app, I create a report with iReports and setup the chart, when I click on preview button the chart show well in iReports.
Then I copy the file to my reports app folder, I put a jasper tag in a list.gsp with PDF and HTML formats, run de application, and display the view, when I clic on PDF format the chart show well, but when I clic on HTML format the page show a broken image; the page tried to find the 'nullimg_0_0_9' image but it does not find it.
I put the report file in //web-app/reports/GraficaOperacionComercialProgramada.jrxml.
I am using Grails 1.3.6, Jasper Plugin 1.1.6.3 and iReports 4.0 on Ubuntu 10.10.
Any one know what I am do wrong?.
This is the code in my list.gsp:
<g:jasperReport
jasper="GraficaOperacionComercialProgramada"
format="${message(code: 'global.formatosReportes.label')}"
name="Gráfica sobre el total de carga por tipo de operación">
<br>
</g:jasperReport>
This is the report's code:
http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="GraficaOperacionComercialProgramada2" language="groovy" pageWidth="612" pageHeight="792" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20">

It sounds like you need to define your reports directory for jasper plugin. In grails-app/conf/Config.groovy make sure you have property named jasper.dir.reports and its value should be a full path to your jasper or jrxml files.
