Working with jcharts and tomcat 4.1.31

I am trying to use the latest jcharts under tomct 4.1.31. After following the instructions, it is possible to see the jcharts context. The first Example (Pie Chart) shows up fine. When I tried to access the other exmaples, I am getting an error from tomcat server.
 
Is it a know problem? Can I get some help on this issue?
 
Thank you.
Rahul.
