Error when installing Cocoon 2.1.8 under Tomcat 5.5.9

[Joseph Hill <jo...@yale.edu>]

I built Cocoon 2.1.8 and then put the cocoon.war file in Tomcat 5.5.9's 
webapp directory and then when I started Tomcat and went to the Cocoon 
page I got the error messages below.  I'm running Mandrake 10 and am 
using Java 1.5.0-4.  Any ideas on what causes this and how to fix it?

exception
