Createobject - cfinvoke

Hello experts.
I need help to replace the following createobject with cfinvoke.
cfm
<cfset objsheduletask = createobject("component","com.scheduletasks").init(request.dsn)/>
<cfset objsheduletask.fsendundelivered(request.homeurl)/>

cfc
   <cffunction name="init" access="public" output="false" returntype="any">
        <cfargument name="dsn" type="string" required="true">
        <cfset variables.dsn = arguments.dsn>
        <cfreturn this>
   </cffunction>
   <cffunction name="fsendundelivered" returntype="boolean" access="public">
     <cfargument name="homeurl" type="string" required="yes">
 <cfquery name="....." datasource="#variables.dsn#">
.....
     
     <cfreturn true>
   </cffunction>

I could use:
cfm.
<cfinvoke component="com.scheduletasks" method="fsendundelivered">
 <cfinvokeargument name="homeurl" value="#request.homeurl#" >
</cfinvoke>
cfc
<cffunction name="fsendundelivered" returntype="boolean" access="public">
     <cfargument name="homeurl" type="string" required="yes">
      <cfquery name="....." datasource="#request.dsn#">
      .......
     <cfreturn true>
   </cffunction>
Is this correct?
Is there any better way?

Hi myselfrandhawa
I did correct this the same time you posted your comment.


Using the createobject i use the init function to set the dsn.
Using cfinvoke i have to delete the init function and use the request.dsn value.

I'm asking if i do this right

Nothing technically wrong with the way you have it. But using a #request# variable makes the cfc slightly less modular.

Is there any better way?

If you're sure the component is stateless, and not tied to a specific session, yeah. Whichever you're using it's better to create stateless components once (in OnApplicationStart). Then store them in your application scope.  Using your original init() method:

       <cfinvoke component="com.scheduletasks" method="init"
                   dsn="#request.dsn" returnVariable="theObject" />
        <cfset application.scheduleTasks = theObject >

Then when you need to call one of the functions use:

    <cfinvoke component="#application.scheduleTasks#" method="fsendundelivered">
          <cfinvokeargument name="homeurl" value="#request.homeurl#" >
     </cfinvoke>

Just make sure ALL of your function variables are properly var scoped. Otherwise you'll have threading problems.

I'm curious why the change from createObject to cfinvoke.  To me createobject is a cleaner, more intuitive style and easier to assign to an application scope


<cfset application.sheduleTasks = createobject("component","com.scheduletasks").init(request.dsn)/>

Why would you want to change away from it?  (Other than a person preference to cfinvoke?)

Possible hosting restriction? Though my preference is createObject too..
