Sometime I have to use a service locator like because I am in a class that is not a EJB3. A small example: Some of my entities have a @EntityListener. Implementation of the entity listener needs to use a service provided by an EJB3 session. In the source code of the entity listener, I can not use @EJB annotations (not supported). Consequently I use a ServiceLocator to get my session bean. I'm not very happy with that but I have not found a better solution. In there something simpler in EJB3 ?
