tomcat 4 datasources

[Matt Barre]

I know there is a way to configure DataSources using tomcat 4's server.xml file. I've
tried using the default examples to create my own, but so far I haven't had any luck. 
The
docs for this portion of the project appear to not have been written yet. Can anyone 
point
me toward a resource where I can learn more about them?
