RE: Casting java objects in RPG - problem solved

Yup, that's the other way to do it.  When invoking a procedure that
expects an object of a specific class, you can pass an object of that
class OR ANY SUBCLASS.  The Java runtime performs the type checking.  If
you attempt to pass an object that is not a subclass of the required
class, you will get an error.

I wasn't sure what you were trying to do because I didn't see the code
that was actually trying to use the prototype.  In the future, it's
probably a good idea to include that part of your code for these types
of questions.
