In Java EE 7, EJB container has this sole responsibility and it is worth remarking that the EJB container is not the same as the CDI container. Although in some internal implementations of the Java EE 7 standard there may be subtle differences between each bean type. Indeed, in the JSR-342 specification document, there is no mention at all of CDI. It is theoretically possible to rewrite all types of EJBs as CDI managed beans. In future Java EE platform editions, the relationship between the EJB and CDI container should be more clearly defined.
