Hi, I need a basic clarification. will Ajax can be implemented in ColdFusion 5 version(on IIS/oracle 9i). If yes, please help me by providing some information like How to setup engine files and how to get it worked in CF5.

Hi Rob,
Thank you for the introduction for ajax with coldfusion .It is very easy to get started.

did u recognize the Ajax interface as you posted your feedback, or you have no clue what Ajax means?

too bad you didnt use AJAX on this site...

It's become very popular lately, even though it's not exactly new. It's been possible to use the concept behind AJAX since browsers introduced the XMLHttpRequest function in 1999. Enjoy Rob Gonda's highly popular ColdFusion Developer's Journal article on AJAX, the hottest software development of 2005, with plenty more heat promised for 2006.

Neither FF or IE will allow cross-domain scripting.

This is a securiry risk, read more here:

There are ways around it like a Server Side proxy, or third party JavaScripts like Ajax Extend (http://ajaxextended.com/)

Ok had a little time to kill and decided I'd give Ajax a try and see what all the hype was about. Downloaded and installed cfAjax folowed install directions step by step. all seemed fine untill I tried to run one of the sample applications. Then I got the following error.

Permission denied to call method xmlhttpRequest.open

I decided to load a full version of ajax and still got same error In looking for an answer I keep seeing the following as the culprit with no real solution.

This error occurs when you try to make requests off-domain.

which in pouring over the code I cant find anywher that the examples are making calls to off-domain. So lets cover the basics..

yes error is same in both ie and moxilla

no I'm not using a local file (ie //file/ajax/example)

no I dont have a firewall running between my work station and my development server

yes both machines are windows running IIS

yes the url has http (ie http://myDevelopmentServer/ajax/examples/text.htm

yes I created a virtual host for ajax in both IIS and my CF Administrator

So I guess that covers it Any help would be great

Mohan, I am glad I could help; I definitely tried to make the article so easy and straight forward so everyone can get AJAX started. This will be one of the major topics for 2006.

i am new to AJAX this is a wonderful article. After seeing this article i am going to implement CFAJAX in our (production) search form.

Perhaps, nothing really prevented anyone from using it; Jesse James Garrett just had to come up with the idea/concept. By the way, don't miss Jesse at the Ajax Seminar (www.ajaxseminar.com/)

It is indeed; AJAX involves combining any server scripting language with client side, hence, JavaScript. I can see how you could probably automate a two related select boxes without writing JavaScript, but certainly not an RIA or Web 2.0 application.

SYS-CON will soon launch a dedicated online AJAX section but it will not be called "AJAX Developer's Journal" or "AJAX Magazine." Thanks and best regards.

P.S. Please stay tuned for SYS-CON's complete educational offerings to be announced soon.
