    DI in service MBean

    Nick Semchenkov Newbie

      Hi all

       

      I have a service bean (i.e. bean, annotated with @org.jboss.ejb3.annotation.Service)

       

      Is it safe to inject @Stateless EJB into such singleton bean? Does this mean that @Service bean will be linked to the same instance of @Stateless bean throughout all its life?

          Which version of JBoss AS? If you are using AS 6.x then it's recommended not to use the now deprecated @Service and instead use the EJB3.1 spec based @Singleton.

          If you are injecting a @Stateless bean, that the instance selection for the @Stateless happens during invocation on the injected proxy. So it would not always end up on the same @Stateless instance.

            Thanks for reply. I'm currently using the latest stable release - 5.1. It doesn't include support of EJB 3.1 singletons, so I'm forced to use @Service beans.
