    Model Facade Pattern with EJB: Business Delegate/Service Locator?

      I have a couple of questions regarding the "Using an EJB Session Bean as a Model Facade":
      1. Is this for Java EE5 and later only?

      2. Why is there no Business Delegate in the pattern - I thought Business Delegate was supposed to remove tight coupling between Presentation tier and Business Tier. Are you saying the advances in EJB 3.0 makes the Business Delegate obsolete?
