Maybe if you provided us with more context around your thread creation
and how it dovetails in with ibatis. To be honest we can't offer you
advice on something we know nothing about.

directly I'm creating an encapsulated unit of work and running with a new
thread. What I've discovered is that whenever an exception is thrown, the
create Object exists in the database, although commitTransaction has never
been called. After browsing through the mailing list, and eventually the
code, I discovered that the dao manager (DaoContext) is using ThreadLocal to
keep track of transaction and state. Given this fact, is it even possible
to solve my problem without having to change the underlying code or right
some sort of wrapper class.
