Re: RPG/Java interaction

Hi Mark,

That's why I said the following in my first reply of the thread:

In your case, the program would definitely throw an error, so an RPG 
wrapper would work.

I can't tell you why RUNJVA works the way it does.

Indeed, I phrased things that way because I'm not overly familiar with 
RUNJVA -- I am familiar with running Java from RPG, so I pointed out 
that if that is the problem, you could write an RPG wrapper.  In your 
case, that would work.

If you don't like how RUNJVA works, or want to know it's rationale, I'm 
not the person to ask.  Maybe ask IBM.
