      Hi All,

      Please help me and tell me what I am doing wrong

      I have this class with the method deleteSubscriber()


      import java.io.Serializable;

          @Begin(join=true)
          public String createSubscriber(){
               subscriber = new Subscriber();

          public void deleteSubscriber(Integer id){
                subscriber = new Subscriber();
                System.out.println("I got here FIRST");
                subscriber=entityManager.find(Subscriber.class, id);
                        System.out.println("I got here");
               entityManager.remove(subscriber);
               //subscriber = null;
          }
         
          @Destroy
          @Remove
          public void destroy() {}
         
          @End
          public String saveSubscriber() {
               entityManager.persist(subscriber);
               @SuppressWarnings("unchecked")
                List<Subscriber> subscribers = entityManager.createQuery("Select s from Subscriber s").getResultList();
               Contexts.getSessionContext().set("subscribers", new ListDataModel(subscribers));
               return "success";
          }
         
         

      }


      I have this interface

      import javax.ejb.Local;

      @Local
      public interface SubscriberManager {
           
           public String createSubscriber();     
           public String saveSubscriber();
           public void deleteSubscriber(Integer id);
          public void destroy();


      }


      But I still get this error even though the method is present. Someone please help me
