Can you see what that does? I hope so!! .... Come on someone out there must get it!

You're describing a templating system called JSP or Java Server Pages

You should study how JSP came about, the problems it tried to fix, the problems it generated, and how Sun tried to fix them , JSTL... sorry, I have no link

You should also study templating systems in general -- there isn't very much new under the sun
