How do I get the number of active sessions in Xpage. I'm trying to use managed beans but it just returns a weird string. Here's the simple code:

import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;

public class SessionCounterListener implements HttpSessionListener {

  private static int totalActiveSessions;

  public static int getTotalActiveSessions(){
    return totalActiveSessions | 0;
  }

  public void sessionCreated(HttpSessionEvent arg0) {
    totalActiveSessions++;
    System.out.println("sessionCreated - add one session into counter");
  }

  public void sessionDestroyed(HttpSessionEvent arg0) {
    totalActiveSessions--;
    System.out.println("sessionDestroyed - deduct one session from counter");
  } 
}

I got this from here. But when I call SessionCounterListener.getTotalActiveSessions(), it only returns a weird string, example com.gs3.beans.SessionCounterListener@46c446c4. Please help me. Thanks a lot!
