How to make @EJB Annotation work in Tapestry pages and components

This works on Tapestry 5.3 or higher. Has been tested with Glassfish 3.1.

Code excerpts are from Flow Logix Tapestry Library

In your AppModule.java file, add the following method

    @Contribute(ComponentClassTransformWorker2.class)
    @Primary
    public static void provideClassTransformWorkers(OrderedConfiguration<ComponentClassTransformWorker2> configuration)
    {
        configuration.addInstance("EJB", EJBAnnotationWorker.class, "before:Property");
    }

EJBAnnotationWorker.java

(add this to one of your non-tapestry packages)

EJBAnnotationWorker.java

Using Stateless @EJB in your client code

class SomeTapestryPage
{
  private @EJB MyStatelessBeanLocal localBean;
}

Using Stateful Session Beans in your client code

class SomeTapestryPage
{
  private @EJB @Stateful MyStatefulBeanLocal statefulBean;  // stored as SessionState object
  private @EJB @Stateful(isSessionAttribute = true) MyStatefulBeanLocal statefulBean2;  // stored as SessionAttribute object
}
