Too many buzzwords for me. 

For portability, I just use the Java Toolkit, and it runs on any
platform with a JVM.  Portability is a pretty well defined term: runs on
different platforms.  How I connect to the host is an implementation
detail.

But I have no idea what YOU mean by loosely coupled.  Evidently, you
consider HTTP communications using XML to communicate with an RPG
program to be loosely coupled, but I don't agree.  Why it has to talk to
an RPG program is beyond me.  If I'm communicating via HTTP, I may be
talking to a servlet, not an RPG program.  The servlet can invoke the
RPG server.

And why is an HTTP call with XML any less loosely coupled than a toolbox
call to one of the OS/400 host servers?  Maybe I want to use a serial
connection.  Or APPC, for security reasons.  Unfortunately, you've tied
me into TCP/IP with your tightly coupled web services design.

Me, I'll just put a wrapper around the delivery class and reimplement it
as needed, without having to touch my application.  That's the point of
OO design.
