DAO and Batch in Single Transaction

[Gregg D Bolinger]

I am using iBatis SqlMap and iBatis DAO. I am trying to look into
doing batch inserts/updates/delete within a single transaction for
multiple DAO's.  So should I create a Service that just handles my
batches and has an instance of each DAO that it needs, or is there a
different way?  Anyone have any tips or hints on doing this?

Thanks.
