Why? JSPs actually get compiled into a servlet at load time, so they
exactly the same as a servlet. What is does is allow you to separate the
static HTML from the dynamic code. Much like Net.Data. In eRPG I store the
static HTML in files and then read it into the CGI program. Really the same
result except with JSP there are design tools emerging (WebSphere Studio
and Ultradev to name a couple) that allow you to design your JSP pages
with placeholders for the Java (JSP tags).

I think they are very similar in many regards. Getting environmental
is a method call rather than a subprocedure call (assuming you encapsulated
the C APIs in a service program). You can simulate most of the request and
response methods with subprocedures if you want. Doing things with session
is nicer. They do scale better because of spawning threads for each request.
Overall, I see many more similarities than differences. One advantage is
standardization. Everyone uses the same objects and methods where as in RPG
is varies depending on how the subprocedures and service programs are set
The large class libraries available from Sun and IBM provide for a lot of
functionality right out of the box.

I have. In fact I did that based on your MC articles before your book was
