Everyone else gets to webify their "legacy" apps, so why not IBM? We have internal app development shops that are looking for ways to cut support & development costs, too. And those new hires out of college are certainly not very good at 3270 programming, you know.... ;-)
Come on Sir. You're just repeating hearsay nonsense arguments. Yours is almost as good as the one to replace the VM Toolsrun-based employee directory by LDAP because the VM solution "required updates to be applied to all copies of the data spread over multiple VM system" I believe IBM set back the clock 10 years by migrating off their VM applications internally. When you have a decent interface between business logic and presentation layer than served the purpose already for 20 years, really how many people do you think need to be involved with 3270 data stream programming? In fact, that interface was lean enough to allow for small projects to access the applications through web browser or even WAP phone. What really increased development cost was to replace development teams and rewrite the business logic on another platform. Many web applications today still follow that classic "form based" transaction model like we have with DMS, ISPF, IOS3270, or Xedit-based applications. That only model changes with WEB 2.0, and I already demonstrated we can drive an AJAX web application with our CMS-based ESAWEB server. Guess what, the CMS code was just 10-15 lines of REXX and Pipes to make it work. The rest is AJAX just like it would be on another platform. And an application takes a *lot* of AJAX code to make it work, but that's another issue. Rob
