--------------------------------

Ok, I will write a test using your code from the forums to verify.

>                 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
