<Chuckle>Joe, you sound like the Video Professor! Will you refund the shipping and handling?</chuckle> Your statement explaining the benefits of WebSphere have nothing to do with WebSphere; I can accomplish the same thing with CGIDEV2. We'll agree browser-based applications have merit and we don't need to get into quantification. So, the only question is how we get the application to a browser. I'd think tools and utilities for managing JSP's should be high on Toronto's list. -reeve On Mon, 31 Jan 2005 20:03:56 -0600, Joe Pluta <joepluta@xxxxxxxxxxxxxxxxx> wrote: > > From: Reeve > > > > WebSphere may be IBM's Grand Design but the learning curve is steep, > > You haven't had the right teacher.
