    Problem with @Asynchronous

    Hannes Schulz Newbie

      Hi,

      after trying to set up a TimerService without success i was trying to set up a scheduled task with @Asynchronous.

      I ' am running into a similiar or same (i am still not so familiar with seam) error message.

      i wrote an observer which triggers the asynchronous annotated method:

      @Name("initializer")
      public class Initializer {
      
       @Logger Log log;
      
       @In(create=true)
       CacheObserver cacheobserver;
      
       @Observer("hello")
       public void log(String msg)
       {
       log.info("cacheobserver called");
       Calendar calendar = Calendar.getInstance();
       calendar.add(Calendar.MINUTE,1);
       cacheobserver.checkCache(calendar.getTime(),new Long(2000000));
      
       }
      }


      the @Asynchronous annotated method is provided by an stateless bean:

      @Local
      public interface CacheObserver{
      
       @Asynchronous
       public void checkCache(@Expiration java.util.Date date, @IntervalDuration Long duration);
      }
      
      
      @Stateless
      @Name("cacheobserver")
      public class CacheObserverBean implements CacheObserver, Serializable
      {
       @Logger Log log;
      
       public void checkCache(Date date, Long d)
       {
       log.info("check cache!");
       }
      
      }
      



      here is the stacktrace i get:
