tomcat error

All,

I'm new to Sitemesh and I would like to use it in my next project. On
installing the sitemesh-example.war file in my tomcat/webapps directory,
Tomcat complains with the following error msg. The error is the same
whether I user Tomcat 5.0.19 or 4.1.30. I'll include just a portion of the
stacktrace...

Any help would be appreciated. Thanks.
