Coldfusion : How to check that Coldfusion scheduled task is already created or not?

Question :

 Is there any way to check that scheduled task is already created? If not already exists create new one.

Code :

<!--- 1. By using cfobject --->

<cfobject type="JAVA" action="Create" name="Service_factory" class="coldfusion.server.ServiceFactory">

<cfset Service_factory = CreateObject("java", "coldfusion.server.ServiceFactory") />

<cfset Scheduled_Tasks_Array = Service_factory.CronService.listAll() />

<cfdump var="#Scheduled_Tasks_Array#" />

<!--- 2. By Using create object function --->

<cfdump var="#createobject("java","coldfusion.server.ServiceFactory").CronService.listAll()#" />

<!--- 3.By reading the XML file neo-cron.xml--->

<cffile action="Read"

      file="#Server.ColdFusion.RootDir#\lib\neo-cron.xml"

      variable="TaskXML">

<!--- Convert the WDDX to CFML - and array of structs --->

<cfwddx action="WDDX2CFML" input="#TaskXML#" output="Scheduled_Tasks_Array">

<!--- Dump all the schedule tasks in CF Admin in Struct format. --->

<cfdump var="#Scheduled_Tasks_Array#" /> 

<cfif arraylen(Scheduled_Tasks_Array) EQ 0>

  <cfschedule   

    action = "update"  

    task = "test schedule 1"  

    startDate = "01/01/2013"

    startTime = "00:00:00"  

    url = "www.google.com"   

    interval = "900"

    operation = "HTTPRequest"     

  >

</cfif>

Output :

 All the scheduled task data get stored in the XML file at the following location -
#Server.ColdFusion.RootDir#\lib\neo-cron.xml

One more thing, for coldfusion schedule task we can't give interval less than 60 seconds. Otherwise it will throw error as -

The task interval must be greater then 60 seconds.

But I get to know that through the "neo-cron.xml" we can achieve this.Hope this help !!!
