I want to use Esper. How can I use it?

I tried to make a CEP to run an event every 30 minutes. But I don't know how to do that, so I ask.

I looked for the type of cep and tried using esper as I thought fit.

then I try it. But How can I use it???

public void EesperExample2(UserInfoDto udto) {

    Configuration config = new Configuration();

    config.addEventType("SearchYoutubeVo", SearchYoutubeVo.class.getName());

    EPServiceProvider epService = EPServiceProviderManager.getDefaultProvider(config);

    String epl = "select * , count(*) from SearchYoutubeVo.win:time(5 minutes)";

    List<SearchYoutubeVo> vo;

    EPStatement statement = epService.getEPAdministrator().createEPL(epl);

    ExampleListener example = new ExampleListener();

    statement.addListener(example);

    int EventCreateNum = 5;



    //for(int i = 0; i < EventCreateNum; i++ ){
        try {
            vo = youtubeSearchService.searchYoutube(udto);

        } catch (Exception e1) {
            // TODO Auto-generated catch block

            e1.printStackTrace();

        }

        try { Thread.sleep(500); } catch (InterruptedException e) { e.printStackTrace(); }
    //}
}

  public class ExampleListener implements UpdateListener {
public void update(EventBean[] newEvents, EventBean[] oldEvents) {
    EventBean event = newEvents[0];
    System.out.println("Avg Rating of NFM = " + event.get("viewCount") + " Total Count: " + event.get("videoId"));
    System.out.println(event.get("count(*)"));
}
}

'vo = youtubeSearchService.searchYoutube (udto);' Enter a youtube keyword.

'UserInfoDto udto' does not have user information.

YoutubeSearchService.searchYoutube (udto); Data allows you to get data in 5 minute intervals.
