John Ament commented on WELD-381:
---------------------------------
It might be. In my case, I cannot inject instances of the interface. It sounds just like
the problem 305 is addressing, where it adds more interfaces to the bean's types. I
think it would be worthwhile to add in consideration that some interfaces should not be
considered as injection points as well.
Proxied EJBs as Injection point, wrong interface chosen
-------------------------------------------------------
Key: WELD-381
URL: https://jira.jboss.org/jira/browse/WELD-381
Project: Weld
Issue Type: Bug
Components: Resolution (Typesafe and by Name)
Affects Versions: 1.0.0.GA
Environment: GF v3, JDK 1.6, Windows
Reporter: John Ament
Fix For: 1.0.1.CR1
Based on the forum post, The following EJB cannot be injected into clients:
@DAO
@Local(ResultDAOBean.class)
@Stateless
public ResultDAO extends AbstractDAO<Result> implements ResultDAOBean
Happens the same with/without @Local
The problem comes in when AbstractDAO implements something (e.g.
AbstractDAOBean<E>) or ResultDAOBean extends an interfacet
(e.g.AbstractDAOBean<E>). The interface AbstractDAOBean isn't marked as an EJB
itnerface, and only one of these two would implement/extend it (ideally, ResultDAOBean).
The injection point results in the following exception:
Caused by: java.lang.IllegalStateException: Unable to convert ejbRef for ejb ResultDAO to
a business object of type interface AbstractDAOBean
