First ColdFusion Web Service By Ben Nadel on December 12, 2006 Tags: ColdFusion I know, I know, I'm like a decade behind everyone else, but I JUST coldfusion error handling application cfm started playing around with web services. I have just never had to

invoke or provide one before and so never experimented with it. I had kind of a rocky start with

this example, but after some Googling and some Adobe documentation, I got it off the ground.Application.cfc And OnRequest() Event MethodMy first hurdle was getting my application to allow ColdFusion Components (CFCs) to

be called directly. My application uses the OnRequest() event method in the Application.cfc ColdFusion component and as you may or may not know, doing so blocks the use of web services and flash remoting. To get around this, first I created a directory for my web services at "/resources/webservices/". Then, I applied a dirty little trick I picked this up from Ray Camden coldfusion web service security as explained in the first issue of the Fusion Authority Quarterly; I destroyed the OnRequest() event method for web service calls:// Check to see if the target page is in the web services// directory. If it is, then we want to delete the OnRequest// event handler so the web service has access.if (ExpandPath( GetDirectoryFromPath( ARGUMENTS.TargetPage ) ) EQ APPLICATION.ServiceFactory.GetConfig().GetFullPaths().WebServices){// Delete the on request event handler.StructDelete( THIS, "OnRequest" );// Delete the on request end handler.StructDelete( THIS, "OnRequestEnd" );}While I think Ray only recommended the OnRequest() event method removal, my OnRequestEnd() event method was causing issues (via the CFFlush tag) so I had to remove it as well. I placed this at the very end of the OnRequestStart() event method. Since that event method fires before the OnRequest() event method, it is able to successfully alter the pre-page processing event chain. Now, all calls to ColdFusion components (or any other files for that matter) located inside the "resources/webservices/" directory can be accessed directly.
