Understood.
The first thing I did was verify that the class file was there, and it is.

Actually, just noticed that the vm can't seem to load other classes either...here's
the exceptions when I try and execute the numguess example:

No. Similar exceptions.
I'm using JDK 1.3, BTW. Is there an issue wrt this?
Also, I'm letting the script figure out my CATALINA_HOME by simply running the script
from the bin dir. This should work right?
Finally, the TOMCAT_HOME env variable is unused in 4.0m4, right?
Thanks,
Dan
