Accessing CFCs from outside ColdFusion and basic HTML

Macromedia Flash applications that use Flash Remoting MX can easily take advantage of
ColdFusion components for business logic. Similarly, you can export CFCs so that any web
application can access CFC methods as web services.
Using Flash Remoting MX
Flash applications that use Flash Remoting MX can access CFC methods by using the CFC path
as the service name in a NetServices
the CFC methods by appending the method name to the service name as the following example
shows:
gatewayConnection = NetServices.createGatewayConnection();
myServiceObject = gatewayConnection.getService("myService", this);
myServiceOjbect.myFunction( { dept: Sales, name: BobZ });
Note: In ActionScript, you put multiple parameters in curly braces ( { } ) and separate parameter
names and values with colons (:).

Invoking components as web services

Any web application, whether it is a ColdFusion application, a Java application, JSP page, or a
.Net application, can access well-formed ColdFusion components as web services by referencing
the WSDL file that ColdFusion automatically generates.
To see a component's WSDL definition, specify the component web address in a URL, followed
by ?wsdl, for example:
http://localhost:8500/MyComponents/arithCFC.cfc?wsdl
For more information on using CFCs as web services, see
on page 707.
