Deep down inside of Tomcat 4, the Resources implementation class is a
javax.naming.directory.DirContext implementation (from the JNDI API).
You will want to get the JNDI specs (http://java.sun.com/products/jndi) as
you look into this.
A good starting point would be to look at the following classes in the
org.apache.naming.resources package:
* BaseDirContext - Convenience base class for resources implementations
* FileDirContext - Implementation used when you run a webapp from an
unpacked directory
* WARDirContext - Implementation used when you run a webapp directly
from a WAR file
The mechanism by which the right resources implementation is selected is a
little obtuse, and I've never actually tried replacing it via the
<Resources> element, but it should be possible.
