RE: starting JVM is slow

["Bartell, Aaron L. (TC)" <ALBartell@xxxxxxxxxxxxxx>]

Just curious, what are your reasons for not calling RPG from Java?  I have a
Servlet in production calling an RPG program with PCML as the intermediary,
and it is very very fast.

I agree that calling Java from RPG is pretty much useless unless it is a
batch process or if you have a huge machine.  People will tell you to use a
data queue or something similar, but that means you most likely need to
write your Java interface so it can run off of a completely validated data
queue record (meaning you don't collaborate with all the different methods
in a Java class).

Hi,

IMHO best practice is: not to call java from RPG and vice versa.
