Can you help?

[Todd Burkard <tb...@thepartnership.org>]

Hello,

I am attempting to get webMathmatica going for our school. I'm not sure if you can help me since the tomcat examples run fine. The error appears to be related to a missing class perhaps? Im not sure what to do.... Below is the error as well as the source of the example that causes the error (They all error out). Any help/guidence you can provide would be greatly appreciated.

Sincerely,
- Todd Burkard


This is the error when I attempt to use one of my webMathmatica examples:
