Joe- Perhaps an approach that combines your idea and mine. The
getColumn() method returns an Object, then another program takes the
object and calls the "instanceOf()" method to find out the actual
class, then it fills in the data structure that you proposed. Then
passes a pointer to the populated datastructure back.
Using this combined approach, the "getColumn()" method doesn't have to
deal with populating the datastructure.

It would also simplify error handling. If the "instanceOf" method
returns something that is not usable from RPG, then the Java program
can throw/log an exception.
