Multiple Web Applications on Tomcat

Here is the top level of the umdcs web application created in an earlier exercise:
- http://redrock.d.umn.edu:8081/umdcs/
Falkner and Jones have created a web application that contains all the examples from their book. Here it is on the same Tomcat server:
- http://redrock.d.umn.edu:8081/jspbook/
Web applications can be zipped into WAR (Web Application Resource) files that are functionally similar to JAR files.
If references to resources are relative rather than absolute, WAR files can be extremely portable.
