I recently started using struts 2 by experimenting with webwork and then
moving to struts 2. I want to produce some charts using jfreechart. After
getting the example
(http://wiki.opensymphony.com/display/WW/JFreeChartResult) to work using the
webwork framework I tried it with struts
2(http://struts.apache.org/2.x/docs/jfreechart-plugin.html). I have not had
any success.
I'd really appreciate it if someone could help get me past this obstacle.
(the first action is working correctly)
Thanks in advance!

You have 2 packages with the same namespace, and 2 actions inside with
the same name. So given:
/ccbill/viewModerationChart
there are more than one entry, which is illegal.
Make sure that namespaces are different.

I have discovered the problem. I had not put jcommon.jar in lib directory.
It was there for me when using webwork quickstart and I had not realized its
necessity. Thanks for all your help - I don't know if and when I would have
discovered the problem without it.

It seems more times than not the war does not load if the viewModerationChart
action is in struts.xml. It doesn't matter what the namespace is. This is
the catalina.out log with namespace="mychart".
