> I experienced the following confusing behaviour in Tomee/OpenEjb when trying to construct a builder pattern with a @stateless session bean. When I return "this" from a builder pattern method, container managed transaction seemst to get lost. E.g a call to an EntityManagers persist() method, will throw a TransactionRequiredException.
> For reproduction figure this ejb (pseudocode):
> {{{}@Stateless{}}}{{{}class MyEjb {{}}}{{{{}}{}}}{{{}@PersistenceContext{}}}
> {{EntityManager em;}}
> {{public MyEjb getMe(){}}
> {{doSomeInternals();}}
> {{return this;}}
> {{}}}
> {{public void createSomething(){}}
> {{em.persist(new SomeEntity());}}
> {{}}}
>  
> in some client, if I call:
> {{myEjb.createSomething()}}
> the entity is created and stored. However, when I call
> {{myEjb.getMe().createSomething();}}
> the TransactionRequiredException is thrown.
>  
> Question:
> Is this an intended behavior? (I couln'd find any documentation in EJB why this would not be allowed to do. )
>
