I also posted already posted an example for Ian showing the jQuery/CF7 portion of the code:
http://blog.pengoworks.com/index.cfm/2011/3/3/Easy-AJAX-using-ColdFusion-jQuery-and-CFCs The example does deal w/a struct, but converting data to a struct is very straightforward. I know he's seen it--because we had an offlist brief discussion. The only piece of the puzzle he needs to work out is the web service part--which may end up being extremely easy, or extremely difficult--depending on the web service he's trying to consume. If CF7 can handle the format natively, then it's very straight forward. However, if CF7 throws errors accessing the web service, then he's going to have to find other method of consuming the web service. -Dan On 3/14/2011 9:20 AM, Dean Lawrence wrote: > > Ian, again you are mixing things up.CFJSON is not what calls the > webservice.
