I don't think OJB is the way to go for you.
Why don't you use the RDBMS bulk load utility?

Subject: AW: Is OJB the right solution?
I'll explain our situation in more detail:
We have an existing infrastructure of Components (EJBs) and an underlying
Database. Persistance of these Components is achieved 'traditionally'
(without
O/R - Mapping tools).
We want to import Data from other Datasources (Access / CSV / Oracle,...)
into
our System. This means we don't need an persistance layer. But we need an
comfortable
(configurable/generic) way of importing this Data into our existing
Objectmodel.
Basically we want to say 'import TableA.fieldA to ObjectB.fieldA'
All we need is a generic 'loading facility'.
I'm not sure if OJB is the right tool for this purpose.
Thanks for helping!

Just from the description you gave it is likely that OJB would help
solve a lot of your problems, but I am not sure without details.
By "import" do you mean use multiple datasources for the application to
materialize the same type of object, or do you mean import data from
one schema (in database one) into database two, using database two's
schema. I think you mean the first situation -- and can say with a
definite yes that OJB can work well for you. You will need to be
careful about object relationships across datasource boundaries... hmm,
fun problem.
