             Summary: Return "this" on stateless EJB method looses container transaction management
                 Key: TOMEE-3816
                 URL: https://issues.apache.org/jira/browse/TOMEE-3816
             Project: TomEE
          Issue Type: Bug
          Components: TomEE Build
    Affects Versions: 8.0.8
         Environment: TomEE 8.0.8, MS Windows 10, OpenJDK 15
            Reporter: Makkus B.


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. )
