The last I used Java's integration to RPG, specifically PCML, I made some
good progress but then was stopped by a brick wall.  The brick wall was a
limitation on the number of parameters that could be passed (i.e. seven
parms max at the time), the lack of being able to pass date data types, and
the lack of being able to pass back anything other than an int in the
passback parm of an RPG sub procedure.

Forgive my ignorance... but what's the point of PCML? Why not simply call an RPG service program as a native method? Or use SQL and make it a UDF? Or a stored procedure?

What advantage does PCML provide?
