I just tried it and my CFC is still returning the JSON content but it seems
like it still appears to be a string rather than an object. I'm using this:
//var wsURL =
'/ws/emp.cfc?method=getEmpInfo&returnFormat=json&searchParam=101';
var wsURL =
'http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any
&format=json&jsoncallback=?';
$.getJSON(wsURL,
function(jsondata) {
// fnPopEmpList(jsondata);
alert(jsondata);
alert(jsondata.items[1].tags);
// $.each(jsondata.items,
function(i,item){
// alert(item);
// });
}
);
When I use Flickr, alert(jsondata) displays [object Object] and I can access
elements like array notes; when I use my CFC alert(jsondata) displays a
string and trying to access elements results in "undefined".

jQuery doesn't read WSDL (afaik). Therefore - you don't want a WSDL
response. You want a JSON response.
You can call any CFC, under web root, with just the url. Try it. Put this
CFC under your web root:
<cfcomponent>
<cffunction name="sayHi" access="remote" returnType="string"> <cfreturn "Ray
roxors"> </cffunction>
</cfcomponent>
If you name this test.cfc, and put it in web root, open your browser to:
http://yourhost/test.cfc?method=sayHi
You wlll see a response. If you view source, you will see it is XML, in this
case, WDDX. To switch to JSON, do:
http://yourhost/test.cfc?method=sayHi&returnFormat=json
Any CFC under web root, and any method with access=remote, can be directly
called by your ajax code.
