I'm not an expert on WebSphere, but perhaps I can
offer some insight.

WebSphere is a layer that sits on top of the AS/400
HTTP server.  Basically, you can configure the HTTP
server to either serve requests itself, or to pass
on the requests to WebSphere.  WebSphere Application
Server (AKA WAS) comes in several versions.  I believe
"WAS Standard" comes standard with your AS/400.  WAS
Standard supports Servlets and Java Server Pages
(JSP's).  This already provides some fairly powerful
functionality that should help you write some fairly
sophisticated web apps quickly.  For AS/400 programmers,
I think it's worth learning Java for.

"WAS Advanced" also provides Enterprise JavaBeans, but
you pay extra for that and it requires learning
additional Java skills.

One more consideration:  Java servlets and JSP's are
fairly portable between different systems (unlike some
other languages commonly used on the AS/400).  A web
app implemented on some other system should be able to
run on an AS/400 with little difficulty.

Cheers!  Hans
