I managed to get the <img src tag to render the chart correctly. Problem
was a sill "/" in the namespace definition of package defining
jfreechart actions in struts.xml. I still have a problem with the ajax
side.
The following
<img id="indicator1" src="/images/indicator.gif"
alt="Loading Info" style="display:none"/>
<s:url id="ajaxCallUrl" value="/chart/ViewSimpleXYChart.html"/>
<s:div theme="ajax"
href="%{ajaxCallUrl}" loadingText="Loading
Chart..." indicator="indicator1">
</s:div>
Gets to the action and returns the chart, but renders it as text in the
<s:div. I must somehow tell to render it as a png. This is on IE7. On
Firefox I get the following error:
FATAL exception raised: Could not load 'struts.widget.Bind'; last tried
'__package__.js'
I have <s:head in my <head> section to enable ajax.
With firefox, if I comment out the sitemesh filter in web.xml, I get the
same results as in IE7.?

I don't know enough about Charts to determine if they're using an HTML
template loaded from a JAR file or anything like that. My guess is not.
If you can render an image from going to a specific URL in your browser,
you should be able to use a regular <img src=> tag to point to that URL
and render the image in your page. Maybe you don't need to use Struts'
<img:> tag?

Thanks Matt for the reply,
I am really quite confused. If I try src="/chart/ViewSimpleXYChart
.html"
I still get a There is no Action mapped for namespace /chart and action
name
Exception.
I don't understand how the menu finds the action though. In menu-config
I have
<Menu name="XYChartMenu" title=" menu.xyChart"
description="XY Chart Menu"
page="/ViewSimpleXYChart.html" />
which renders the chart, but not to my jsp
Also if I add a namespace="chart" to the chart package definition in
struts.xml then the menu does not work anymore even if the page
parameter points to page="/ViewSimpleXYChart.html" />
Do I maybe need to change anything on the struts filter in web.xml ?

Looking at your action definition, I believe the URL should be
src="/chart/ViewSimpleXYChart.html".

fundamentally simple here. The action will generate the chart as png,
and the getChart method place it on the value stack and the references
in the jsp get it from there and display it in the <s:div section ? I
intend using this type of ajax method for a dashboard using Jfreecharts.
