This is a snippet from a program I wrote a while back. It is a method
to create a workorder that returns an int (status). I ran it as an
application and another version as a servlet. It calls a CL to setup
the environment on the 400 which then passes the input parms to an rpg
program. On a 620 there were no speed problems. Also wrote and tested
on a pc with the jdk1.2 and ported to the 400 under 1.1.7 and it ran
with no problems.
A couple of quirks. I have a continue in the IOException catch because
for some reason the call didn't happen on the first try being run as a
servlet. Java programs cannot cross activation groups. So if your rpg
is in a named act group the program will not run. I had to bind all of
the modules by copy. CLLE, RPGLE into 1 program object that was called.
The date is REALLY a packed decimal on the 400 (LEGACY).
