I think Paul and I mis-communicated on the point of the iBATIS DAO earlier.
It is something very different from iBATIS SQL Maps.
One of the key principles of Object-Oriented programming is
encapsulation – the separation of an implementation and its public
interface. The DAO pattern

So true, plus a good DAO interface can decouple your database access
implementation and the rest of your app, so that you can switch from
hibernate to ibatis or plain jdbc or whatever without having to make
Whats about a thread local variable to store the connection instead of
as instance variable ?

Hi Paul,
How about using a DBCP, that way the connections are always there, a getting a connection each time
you need to do a unit of work becomes less of an overhead. With dbcp you can create your connection
by using an xml file usually named 'something.jocl', drop this into you classpath an
You can (and should) use the DAO pattern with Hibernate, too.
The iBATIS DAO even has built-in support for hibernate (of course, it
has support for sql maps, too).

pattern I designed for myself!! One accepted a
connection for transactions, the other for
self-contained singleton executions. Yup, it's a great
pattern.
You raise an interesting point. I never thought about
using a middle-man between my bus

Have you looked at using something like the iBATIS DAO?
I think it could save you alot of pain.
One thing to watch out for is thread safety - putting a connection on
an instance (especially a shared instance) is pretty risky, especially
when you start thinking about transactions and the like...th
