AFAIK, there is no pattern.
You can configure a datasource through Spring, or you could get it
from JNDI once when your app starts (by writing a
ServletContextListener)

Yes,
This is what I want to do.
I am just getting underway with this new project, and am looking for a
solution to handle this. I have read the full O'Reilly struts book,
I wouldn't even store the DataSource. You may wish to have multiple
DataSource instances you wish to use in a given project.
I have Business Objects that extends a "BaseBO" object, which are
generated by a factory (the factory reads an XML file using digester).
My DAOs are generated similarly.
