ColdSpring will make your life much, much easier in the long run...
Here's how I handle JSON requests from jQuery, for instance. Your
mileage may differ:
ColdSpring creates a dataobject which is injected into a service. (I
do everything with stored procedures, so I just create a "dataobject",
and not "DAO" and/or "Gateway"). I then created a simple proxy object
that accesses the service layer from anywhere within my application:
<cfcomponent output="false" hint="Used by jQuery Ajax getJSON function
calls" displayname="proxy Service">
<cfsetting showdebugoutput="no" enablecfoutputonly="yes"/>
<cfcontent reset="yes" />
<!---ColdSpring--->
<cfset variables.sf = application.serviceFactory />
<!--- general-purpose proxy function...will pass through any method
and arguments thrown at it to the underlying service --->
<cffunction name="proxy" access="remote" returntype="any"
output="false">
<cfargument name="service" type="string" required="yes"/>
<cfargument name="remotemethod" type="string" required="yes"/>
<cfset var svc = variables.sf.getBean(arguments.service) />
<cfset var outvar = 0 />
<cfinvoke component="#svc#" method="#arguments.remoteMethod#"
argumentcollection="#arguments#" returnvariable="outVar" />
<cfif isDefined('outVar')>
<cfreturn outVar />
</cfif>
</cffunction>
</cfcomponent>
I can then call any method from jQuery:
$.getJSON('model/services/proxyService.cfc', {
method: "proxy",
service: "someService",
remotemethod: "someMethod",
var1: $("#fieldA").val(),
var2: $("#fieldB").val(),
returnformat: "json"
}, function(data){
....do something with the data....
}
});
