Aren't web services supposed to be easy?

my web service.

<cfcomponent>
    <cfproperty name="id" default="10" type="numeric">
  
  <cfset variables.id = 10>
  
    <cffunction name="setId" access="remote" returntype="void">
        <cfargument name="id" type="numeric" required="yes">
        <cfset variables.id = arguments.id>
    </cffunction>
  
  <cffunction name="getId" access="remote" returntype="numeric">
      <cfreturn variables.id>
  </cffunction>
</cfcomponent>

my test page.

  <p>Call component as web service</p>
  <cfset myWS = createObject("webservice","http://10.104.106.39:8080/ian.cfc?wsdl")>
  <cfoutput>#myWS.getId()#</cfoutput>
  <cfset myWS.setId(888)>
  <cfoutput>#myWS.getId()#</cfoutput>
  <cfdump var="#myWS#">

Both outputs are outputing the same value of 10.  The web service does not seem to be maintaining state from one method call to another.
