Erik,
Oh, I have worked on a project where that was the
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 business tier and DAO.
I'll have to think about that.
And yes, I do use connection pooling -- good point! I
guess there is not a performance gain in keeping the
connection around at the instance level. Perhaps I am
being scrupulous and trying to save time with the pool
code, but that's ridiculous. It's better to put it
back in the pool because at the millisecond level,
many more threads could be using it in between my
thread.
And, I like the IBATIS idea described by Larry... but
sorry, I love Hibernate :-) I don't use it yet, but I
am on board whenever I get to use it.
Thanks!
Paul
