For the prototype, define the parameter as an array of objects.  If you
will always pass the same size array, use that size for the prototype's
DIM keyword; otherwise use the maximum (32767) and options(*varsize).

For the array, just define the object type with the Dim keyword.  Then
instantiate each element the usual way.

D someMethod        pr         extproc(*java:'ThatClassB':'someMethod')
D   myClass                o   class(*java:'MyClassA')
D                              dim(32767)
D                              options(*varsize)

D   myArr           s      o   class(*java:'MyClassA')
D                              dim(whatever)

D newMyClassA       pr     o   extproc(*java:'MyClassA':*constructor)
D   parms...
:
:
   myArr(1) = newMyClassA (parms);
   ...
   someMethod (myArr);

If you haven't already read the Java section in chapter 10 of the ILE
RPG Programmer's Guide, I recommend you do.  There's a table of type
equivalents.
