Tyrex is the *default* connection factory, which you can use on top of any
JDBC driver (including the one from Oracle). It does not include a JDBC
driver of its own, but you declare the name of the driver you want to use
via a "factory" parameter nested inside your <ResourceParams> element to
name the factory class.
You can use a different connection factory by writing an object creation
factory (like the ones already present in Tomcat's
org.apache.naming.factory package) for the new one. The JNDI
documentation (http://java.sun.com/products/jndi) talks about this -- see
the specification for the Service Provider Interface.
There is a small example of adding your own custom resource factory at the
bottom of the "jndi-resources-howto.html" page in the Tomcat 4 docs.
