Ajax using XMLHttpRequest and Struts

Little did I know that only a few years later the basic concepts behind what I had done would re-emerge in the world as something called Ajax. Ajax is a term coined by the folks at Adaptive Path and is shorthand for Asynchronous Javascript + XML.
This just goes to show, patenting every idea you ever have is indeed a good way to riches! If only I would have thought what I did was anything special! But I digress…
Google is doing it. So are many others. But what is it? In a nutshell, the Ajax concept, which is not a concrete technology implementation but rather a way of thinking and a set of techniques that go along with the mindset, is concerned with the idea that rebuilding a web page for every user interaction is inefficient and should be avoided.
The Ajax concept is based around something called the XMLHttpRequest component. All you Microsoft haters get ready to yell because this was a Microsoft creation! Yes, Microsoft got something right, and did so before anyone else! Microsoft first implemented the XMLHttpRequest object in Internet Explorer 5 for Windows as an ActiveX object (ok, so they didn’t get it QUITE right!). The Mozilla project later implemented a native version with the release of Mozilla 1.0, and by extension, Netscape 7. Apple has now done the same as of Safari 1.2. Opera is now following suite with their version 7.60. All released versions of Firefox contain it as well.
