    get bean class: getBeanClass()

      Hello Weld-Experts,

      I wonder if the BeanManager is the only way to access the Bean<?> Interface of Weld/CDI ManagedBean objects.

      In my DAO scenario the only way I managed to guess the Entity type of a parameterized EntityHome was the following:


      MyEntityHome extends EntityHome<MyEntity> {

      ...

      }


      EntityHome<E> {

      ...

      private Class<E> entityClass;

      ...

      private Class<E> getEntityClass() {

      if (entityClass == null) {

      Set<Bean<?>> beans BeanManager.getBeans(getClass().getGenericSuperclass()); 


      for (Bean<?> bean : beans) {

      Type type = bean.getBeanClass().getGenericSuperclass();

        if (type instanceof ParameterizedType) {
       
        ParameterizedType paramType = (ParameterizedType) type;
       
        entityClass = (Class<E>) paramType.getActualTypeArguments()[0];
       
       
        } else {
       
        log.error("NO PARAMETERIZED CLASS: Could not guess entity");
       
        }


      break;



      }  

      return entityClass;

      }

      ...

      }


      Anybody with a smarter way to do this?
