Re: Microsoft .NET frontending IBM i

We all have existing code bases in RPG, it isn't hard to convert those to
output to a CGI XML or JSON type format and push all of that to the web.
Then the web apps talk directly to the RPG programs. The only decision that
web program has to make is if the field should be bold or red. However that
data is sent to the browser really doesn't matter. If all you know is RPG,
then you use that. If you know ASP.NET, Java, PHP, Ruby, Python, etc. that
shouldn't matter. There may be a time when you are asked as to why that
expensive box is sitting there not being used. You simply say we have x
amount of dollars and years of solid code that drives the website. Getting
rid of it will cost us x dollars and x years to get to the same point we are
at today. We all know that rewrites tend to be disastrous in the end.

I know it really isn't that easy in business, but given the right data, a
business should be able to make the, hopefully, right decision.

Are you sure? In my office, we were just the issue of deleting courses
from our
course catalog. What if child records exist? Course Prerequisites?
Course
Objectives? What if a class has already been scheduled that taught that
"course"?

Do you want to move all that investigation and decision making down to the
servlet?

In our scalability discussion, Java experts were just suggesting that
developers
might need to serialize methods that implement business rules like that.
The
application server won't do it for you. Are you sure you want to move that
type
of processing to the servlet?
