Issue

• Suppose that you have the following scenario for injecting a singleton EJB into another using annotations:

  • Singleton EJB bean2:

  @Singleton
  @LocalBean
  public class Bean2 {
  
  /**
   * Default constructor.
   */
  public Bean2() {
      // TODO Auto-generated constructor stub
              System.out.println("In Bean2");
      }
  
  }
  

  • Singleton EJB bean1 having Singleton EJB bean 2 injected in it using annotation:

  @Singleton
  @LocalBean
  public class Bean1 {
  
  @EJB
  private Bean2 bean2;
  
  }
