Re: RPG/Java interaction

Doug,

I'm assuming (since I'm not familiar with your applications) that the 
reason you'd get "end code 0" is that the program isn't reporting an error.

Does that mean that the Java program isn't throwing an error message 
back to it's caller?

Or does that mean that is sending a message, but RUNJVA is ignoring it 
and proceeding as if nothing went wrong?

If the Java program isn't throwing an error, it doesn't matter what you 
do in the RPG program -- the problem is on the Java side.   But if it is 
throwing the error, and RUNJVA is ignoring it, then you could, indeed, 
write an RPG program to solve it.
