Trying to use PubNub java object - the "hereNow" method.

I have included the Pubnub-4.0.0.jar file into my webroot.

(Pubnub-4.0.0.jar can be downloaded here: https://www.pubnub.com/docs/java/pubnub-java-sdk-v4)

I am trying to get the “HERE NOW” java code into my coldfusion project and am having some trouble in doing so.

The java code is as follows:

PNConfiguration pnConfiguration = new PNConfiguration();

pnConfiguration.setSubscribeKey("SubscribeKey")  

PubNub pubnub = new PubNub(pnConfiguration);

pubNub.hereNow()

    .channels(Arrays.asList("ch1", "ch2", "ch3")) // who is present on those channels?

    .includeState(true) // include state with request (false by default)

    .includeUUIDs(true) // if false, only shows occupancy count

    .async(new PNCallback<PNHereNowResult>() {

        @Override

        public void onResponse(PNHereNowResult result, PNStatus status) {

        }

    });

My corresponding Coldfusion code is as follows:

<cfobject type="java" class="com.pubnub.api.PNConfiguration" name="objPNConfiguration" >

<cfset PNConfiguration = objPNConfiguration.init() >

<cfset PNConfiguration.setSubscribeKey("SubscribeKey") >

<cfobject type="java" class="com.pubnub.api.PubNub" name="objPubNub" >

<cfset pubnub = objPubNub.init(PNConfiguration) >

<cfset tmp = pubnub.hereNow({channels: "ch1"}) >

<cfdump var="#tmp#" >

I do not get any errors returned.

I feel the way in which I am calling the “hereNow” method is incorrect or the way in which I am trying to display the results is incorrect.

Can anyone provide any assistance with regards to this?

Thanks
