Single table for a 1:1 association

[Lynn Monson <ly...@nextpage.com>]

My apologies in advance if this is a newbie question.

I have two objects, ObjectA and ObjectB that are in a 1:1 association.
I'd like to map them both to a single DB table using one row to hold a
pair of ObjectA/ObjectB instances.  For example, if the objects look
like this:

class ObjectA {
     int id;
     String name;
     ObjectB b;
     ...
}

class ObjectB {
	int foo;
 	int bar;
	...
}

I'd like single table that contains "id", "name", "foo", and "bar" as
separate columns.

I can see how to use a RowReader to read ObjectA/ObjectB instances in
from a single table, but I can't see how to write an instance of
ObjectA/ObjectB out to the same table.

Any help is greatly appreciated.
