RE: Remote Java calls to RPG AS400 programs ?

Tim,

I am a novice at this, but I don't see a lot of people jumping in, so here's
my 2 cents. Because you are talking about Java and Weblogic, I suspect that
the Java programs you refer to are in fact EJBs (Enterprise Java Beans)
running inside of Weblogic. EJBs are a special kind of java program, and
they need an App Server such as Weblogic or Websphere to run them. The java
guys will talk in terms of Session Beans and Entity Beans, and you may want
to revise your paragraph 3 to include the appropriate terminology from their
side. For example, "the Weblogic App Server will instantiate a number of
stateless session beans to service client requests, and these beans result
in and are represented by active prestart jobs in QUSRWRK subsystem on the
AS/400." Note that I said stateless session beans, but that was just my
guess as to what might be on the EJB side - you want to find out from the
java guys what is really on the other end of one of your "openings or
portals."

The only other thing I would warn you about is volume. You don't say
anything about your application, but you do say you are a large company
within a larger company. From what I know about these app servers and EJBs,
they will create more and more beans based on demand and certain tuning
parameters set on the app server. This could potentially result in MANY
concurrent "openings or portals," and you should consider what would happen
on the AS/400 if some large number of these were to open.

Weblogic App Server comes from BEA Systems at www.beasys.com.
