title: Glassfish schedule(timer) exception
body: <p>i am trying repeat <a href="http://www.hascode.com/2012/06/task-scheduling-in-java-ee-6-on-glassfish-using-the-timer-service/" rel="noreferrer">this tutorial</a> on Glassfish 4 and java EE7.
  So i created simple WebApp with maven in Netbeans.</p>
  
  <p>I created simple class:</p>
  
  <pre><code>import java.util.Date;
  import javax.ejb.Schedule;
  import javax.ejb.Stateless;
  
  @Stateless
  public class NewClass {
  
      @Schedule(minute = "*/1", hour = "*",persistent = false) 
      public void anyMethod() {
          System.out.println("hello "+new Date());
      }
  }
  </code></pre>
  
  <p>But when i am deploing app to the server, i get this exception:</p>
