People enamored of AJAX will use it where it is not appropriate.  This will
cost their clients money.  This is a bad thing.

I don't understand this.  AJAX is simply the ability to make an asynchronous
request.  It is server-agnostic; it will speak to JSP as well as CGI.  The
reasons for using JSP over CGI are just as valid in a browser client that
has AJAX as one that does not.

Yup.  As I've written previously, AJAX is just a cool new phrase for the
existing XmlHTTPRequest, which was created about 10 years ago for the
Outlook webmail client.

Bob, you're losing me.  I've been GUI-izing applications for fifteen years.
First it was screen scrapers, then it was client/server, then it was the
browser.  AJAX is but a blip on that particular historical chart.

No, the point was simple: the right tool for the right job.  Don't use the
shiny new hammer when the old screwdriver was the right tool.  And the crack
about code-stealing-clerks is simply mean spirited.  I know LOTS of really
good RPG programmers who will never learn OO, and lots of procedural
programmers will never get their heads around either HTML or event-driven
programming, which is essentially what AJAX is: event driven HTML.

Actually, I disagree with you because you don't differentiate between large
enterprise Java applications and the very thin JSP Model II code that I
advocate.  I equate the learning curve for the 1000 or so lines of Java code
required to implement JSP Model II roughly equivalent to learning how to
properly implement subprocedures in RPG.
