This is exactly how I've always done the DAO in Struts. I'm looking
into Hibernate now, but don't yet see it's value over the POJ J2EE
way.

I suggest not involving Struts at all when it comes to configuration of and
access to data stores.
Write a ConnectionManager (sounds like you've already got that idea), who will
be in charge of Connections. In the ConnectionManager's init block or
constructor, look up your DataSource using a JN

Most everyone was likely routed through this when they found the list

So far as how to acquire a DataSource/Connection goes, JNDI is a
fantastic tool for allowing your persistence layer acquire a

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.

Yaakov.

Scott,
1) I hope the code you showed is sitting inside a DAO, not your Action.
2) It looks much messier because you are not using something like a
ServiceLocator Pattern. Look up and cache the reference to your DataSource
there. It's cleaner and way faster than doing it every time in your DAO.
3)
Rick has some GREAT struts stuff here:
http://reumann.net/struts/ibatisLesson1.do
He talks about using a DAO pattern, and getting that connection type
of stuff (as well as other JDBC specific stuff) out of your
application code.

I think you can still use your DAO classes in Struts. In my application,
which was not written in Struts I use DAOs written as Singleton, Factory
DP everywhere, I guess in Struts you can call your DAOs from Action
Class to access database.

Why not use something like iBATIS to eliminate the need for connection
