default context

[Chad.Davis]

As I read the context docs ( 
http://tomcat.apache.org/tomcat-7.0-doc/config/context.html ), the only way to 
define a default web application is via a context element in the server.xml 
file.  Is this true?  So, this means that it is IMPOSSIBLE to drop a default 
web app WAR into the webapps folder, correct?
