Trouble with demo servlet

[Erich Kilmer]

(Note: this is a copy of a topic I posted at SourceForge before I found this nice forum.)
I just downloaded JFreeChart 0.8.1 and I am trying to get the servlet demo working. I am using WebLogic and I am trying to get the servlet demo working in an existing web app (just to keep it simple). I have placed the JFreeChart jars in my web apps WEB-INF's lib and classes directory. In my WEB-INF web.xml file I have put:
<servlet>
<servlet-name>JFreeChartServletDemo</servlet-name>
<servlet-class>com.jrefinery.chart.demo.JFreeChartServletDemo</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>JFreeChartServletDemo</servlet-name>
<url-pattern>/JFreeChartServletDemo</url-pattern>
</servlet-mapping>
After adding the above I restarted WebLogic.

Does anyone have any advice they could please give me?

Hi again,
I found that if I took the extra periods out of the jar names Weblogic then redeployed them correctly and the demo works.
I renamed jfreechart-0.8.1.jar to jfreechart.jar and jcommon-0.6.1.jar to jcommon.jar.
Maybe its a bug in WebLogic or something?!
Thanks!
