NoClassDefFoundError typically means that you have a class file or a JAR 
file that is not the version your application is expecting.

Do you have a previous install of Tomcat or something else hanging 
around on your system?

I would verify that you only have one copy of things like servlet.jar, 
etc., that the copies are the copies and versions you expect, and that 
your paths are set correctly.
