No.

I guess you want to represent certain fields in class B and have them as an
attribute in Class A (but all fields belong to the same schema), then it can
be a worthwhile addition to Solrj. Can you open an issue? A patch would be
even better :)

I guess this is not a very good idea.

The document itself is a flat data structure. It is hard to see that
is nested datastructure. If allowed , how deep would we wish to make
it.

The simple solution would be to write setters for "b_id" and "b_name" in class A
and the setters can inject values into B.
