Exception while creating Continuous Query.

[Amit Hora]

I am trying to do a POC on Continuous query feature of Apache Gemfire but
getting below exception

Caused by: java.lang.IllegalStateException: CqService is not available.

I have created my region using

create region --name=Student --type=REPLICATE --enable-statistic=true
--enable-subscription-conflation=true

Kindly find below code i am using for creating QueryService and registering
for CQ

@Bean
    QueryService getQueryService() throws CqException,
QueryInvalidException, CqExistsException, CqClosedException,
RegionNotFoundException{
          ClientCache cache =appContext.getBean(ClientCache.class);

          QueryService qservice= cache.getQueryService();

          CqAttributesFactory cqf = new CqAttributesFactory();
          cqf.addCqListener(new CqListener() {

            @Override
            public void close() {
                // TODO Auto-generated method stub

            }

            @Override
            public void onEvent(CqEvent aCqEvent) {
                // TODO Auto-generated method stub
                System.out.println("Event Recieved !");
            }

            @Override
            public void onError(CqEvent aCqEvent) {
                // TODO Auto-generated method stub

            }
        });
          CqQuery studentTracker=qservice.newCq("StudentQuery","SELECT
name from /Student where rollNo==0",cqf.create());

//        qservice.executeCqs("/Student");
          studentTracker.execute();
//        System.out.println(qservice.getCqStatistics().numCqsActive()+"
*****************");
          studentTracker.close();
          return qservice;
    }

Even i tried starting CqService manually but no Luck! same error
  PoolFactory pf = PoolManager.createFactory();

pf.addLocator(PropertiesCache.getInstance().getProperty("hostname"), 10334);
//            pf.addServer("localhost", 40404);
            pf.setSubscriptionEnabled(true);
            Pool pool = pf.create("client");

          QueryService qservice= pool.getQueryService();
          CqService  cqService =
((DefaultQueryService)qservice).getCqService(); // cqService not available.

          cqService.start();

It will be a great help if someone can share working example for Gemfire
