<Chuckle>Joe, you sound like the Video Professor!  Will you refund the

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.
